Can Refinancing Your Student Loans Lower Your Interest Rate?

Can Refinancing Your Student Loans Lower Your Interest Rate?

Yes. The main point of a refinance is to get a lower rate, and graduates who qualify can save serious money.

Interest Rate, Explained

An interest rate is the rate charged to borrow money. Interest is calculated as a percentage of the unpaid principal amount. Federal student loans have a fixed rate, while many private student loans have a fixed or variable rate.

Student loans generate interest daily. Lenders typically add the accrued interest to the balance each month when the bill is generated.

The interest rate paid on any loan may make a big difference. If you have $75,000 in student loan debt and 20-year repayment term, the difference in interest paid with a 6.5% rate and a 4% rate is over $25,000.

To refinance student loans, people with excellent credit and a healthy income — or a solid cosigner — will generally qualify for the lowest rates.

Lowering Your Interest Rate With Consolidation vs Refinancing: How They Differ

For Federal Student Loans

Consolidation is a term reserved for federal student loans and is different from refinancing. Student loans are combined into one loan with a longer term (up to 30 years), reducing the monthly payments. The rate is the average of the existing loans’ rates, rounded up to the nearest one-eighth of one percentage point.

Opting for a Direct Consolidation Loan allows borrowers to retain access to federal programs like deferment, forbearance, and income-driven repayment plans.

But because the new interest rate is the average of the existing rates, rounded up a hair, consolidating loans and drawing out the term usually results in more total interest paid.

Normally, if you had started paying toward Public Service Loan Forgiveness and then consolidated your loans, you’d have to start your qualifying payments over. But a waiver through October 31, 2022, will count repayment on loans before consolidation.

For Private Student Loans

Refinancing means paying off your private or federal student loans with one new loan with a new rate and, sometimes, term.

Refinancing with a private lender may lead to substantial savings.

Then again, it might not be the right move for every borrower. For those with federal student loans, refinancing means losing access to federal student loan forgiveness and income-driven repayment plans.

But borrowers with higher-interest student loans may find the allure of a lower rate — fixed or variable — tempting. If you qualify, you could reduce your payments or save a lot on total interest paid.

Understanding Your Options to Lower Interest Rate

Federal student loan consolidation is meant to make your monthly payment more manageable by lengthening your repayment term, but it will not lower your rate.

Only by refinancing with a private lender can you try to lower your current private or federal student loan rates. This student loan refinancing calculator can give you an idea of how much you could save by refinancing.

Before you start browsing interest rates, take a look at your current loans. How much do you owe? What are the rates? Are you enrolled in any federal benefits, eligible for any, or hoping to be?

Having this information at the ready can provide valuable insights as you start comparing the rates and terms you might qualify for from different lenders. A rate quote is usually quick and entails only a soft credit pull.

After you’ve determined how much you could potentially save by refinancing, consider looking at other benefits offered by the lender.

Refinancing With SoFi

Refinancing student loans to a lower interest rate makes sense for borrowers who are able to do so and who don’t qualify for or need income-driven plans or other federal programs.

SoFi offers student loan refinancing with low fixed or variable rates, as well as access to member benefits at no cost.

There are no fees when you refinance with SoFi, and the application process can be completed online. If you’re ready to take the next step in paying off student debt, get a rate quote in two minutes.

FAQ

What is federal student loan refinancing?

If you refinance federal student loans, a private lender pays them off with one new private student loan that ideally has a lower rate. Federal student loan consolidation is different.

Do low interest rates apply to student loans?

Federal Direct Subsidized and Unsubsidized Loans for undergraduates have a fairly low fixed rate for all borrowers. The rate for Direct Unsubsidized Loans for graduate and professional students is higher. The rate for Direct PLUS loans, for graduate students and parents of dependent undergrads, is yet higher. Most federal student loans also have loan fees that are a percentage of the total loan amount. The fee for PLUS loans has run over 4% in recent years.

Private student loan rates generally are higher than federal student loan rates, but refinancing rates may be quite low for those who qualify. There’s never any cost to refinance, and you can do so as many times as you want.

Can you refinance a student loan for a lower interest rate?

Yes, if you qualify to do so.

Tips for When to Consider Refinancing Your Student Loans

Tips for When to Consider Refinancing Your Student Loans

Editor's Note: For the latest developments regarding federal student loan debt repayment, check out our student debt guide.

If you’re like most borrowers, particularly those with six figures’ worth of student loans from graduate or professional school, you might find that looking at your student debt square in the face is a downer, but repayment can be managed.

Is refinancing a good idea? It can be. When? When you can snag a lower interest rate and in a few other situations.

Student Loan Repayment Plans

Chances are you set up a student loan repayment plan after graduation and figured you’d revisit it later — when you’re making more money, when your career is more secure, when you have more time. The standard repayment plan for federal student loans is 10 years. Direct Consolidation Loans have a repayment period of 10 to 30 years.

Putting off the repayment thought is understandable. After receiving your undergraduate or graduate degree, your focus is on other things (like building a career).

But if you let that nebulous “later” turn into “never,” the repercussions can be costly. At some point, refinancing your student loans could potentially save you a significant amount of money. You just need to figure out if it is the right move for you.

When to Finance Your Student Loans

1. Your Current Student Loans Have High Interest Rates

Look at the interest rates you’re paying on your student loans, particularly federal Direct Unsubsidized Loans (graduate or professional), federal grad PLUS loans, and/or private student loans.

Depending on how high your loan balance is and how much you could reduce the interest rates by refinancing one or more loans, your cost savings may be significant.

2. Your Financial Situation Has Improved Since You Took Out the Loans

Maybe you were a starving student when you took out federal or private student loans, but ideally your financial situation has improved with time. This is great news for your bottom line, because a higher credit score and income help a borrower qualify for lower interest rates.

If you expect to stay on an upward financial trajectory, you might even consider refinancing to a variable-rate student loan, which will have a lower starting interest rate than a fixed-rate loan. Variable rates are tied to market fluctuations, though, which means rates that are very low today are likely to go up at some point.

The upshot is that a variable-rate loan could be a good option for a qualified borrower who intends to pay off the loan at a relatively fast pace.

3. You Don’t Plan to Use Certain Federal Student Loan Benefits

Borrowers who go to work in the public sector may qualify for the Public Service Loan Forgiveness program. Some federal programs also offer relief for borrowers who experience financial hardships (such as student loan deferment and forbearance, income-driven repayment plans, and the graduated repayment plan).

If you expect your income to be unpredictable or you’re looking into qualifying public service employment, it probably wouldn’t behoove you to refinance federal student loans. But refinancing could make sense if you don’t plan to tap into any of the federal programs listed above and you can gain a lower rate.

4. You’re Going to Take Out a Large Loan

For loans like mortgage loans, lenders will look at your debt-to-income ratio, among other things. DTI is your monthly debt payments per month, including your future mortgage payments, divided by your gross monthly income. A low DTI generally signals better odds of loan approval and better interest rates.

Decreasing your monthly student loan payment by refinancing, with, say, a long loan term, could lower your DTI.

It might make sense to refinance your student loans at least six months before buying a home or making any other large purchase. That will give you time to recoup the points lost after a hard credit inquiry.

Once the mortgage or other big loan has been secured, you could refinance again, this time picking the lender offering the lowest rate, not just the lowest payment. You can refinance student loans as many times as you wish.

If you think student loan refinancing may be a good option for you, the next step is to check out several refinancing providers to compare interest rates and other features.

Refinance Student Loans With SoFi

You can refinance both federal and private student loans into one new loan with SoFi in an easy, all-online process. You can get your rate in two minutes.

SoFi also offers access to an extensive member network through complementary member experiences like happy hours and dinners.

FAQ

When should I refinance my student loans?

It might make sense to refinance as soon as you have a stable income and good credit that can usher in a lower rate.

Can I refinance student loans after buying a house?

Buying a home creates new debt, and that can make refinancing student loans more difficult. But by waiting several months or even a year to refinance, the dust can settle on the mortgage decision.

Is refinancing my student loans a good idea?

If you’re struggling to repay federal student loans, you might consider an income-driven repayment plan or federal student loan consolidation.

But if you can qualify, your income is stable, and you would save money by refinancing federal or private student loans, that might be a smart move.

Opening a Business Bank Account

Opening a Business Bank Account: How Business Bank Accounts Work

Business bank accounts can help owners keep professional transactions separate from personal banking and aid in their business cash management. These accounts often come with special conditions and requirements, and they may have various fees.

Here, we’ll take a closer look at these accounts, their pros and cons, and what it takes to open one. Let’s dive into the details about business bank accounts.

What Is a Business Bank Account?

There are three main types of business banking accounts: checking accounts for everyday use, savings accounts for intermediate and long-term savings, and merchant accounts for accepting debit and credit card payments. In this article, we’ll focus on business checking and savings accounts, available from both online and brick-and-mortar banks.

What Is a Business Checking Account?

A business checking account works much the same way a personal checking account does. You use it to deposit payments and make withdrawals, usually an unlimited amount. Like personal checking accounts, business checking accounts typically pay low to no interest on your balance.

What Is a Business Savings Account?

A business savings account will pay more interest than a checking account, so it can be a good place to park cash on an interim basis. You will likely be limited on how many transactions you can make per month without a penalty (typically six), and there may be a monthly minimum balance to maintain. Many business owners find using both a business checking and savings account can meet their banking needs.

How Long Does Opening a Business Bank Account Take?

If you open up a business bank account — whether it’s checking, savings, or both — the time commitment needed is usually similar to that of a personal checking and savings account. It will likely take just a matter of minutes if you have the necessary information on hand. You will need to provide some details about yourself, your business, and any additional business owners involved in your enterprise. Then, you’ll deposit funds. Keep in mind it can take up to seven business days for final approval before you can actually access funds.

What Is Needed to Open a Business Bank Account?

Whether you open your bank account online or in person, you’ll need documentation of several personal and business details. Different banks may have their own verification requirements, depending on the type of business you own and the type of account you’re looking to open.

Here is a general list of what you might need to have on hand to make the opening process most efficient:

•   Your name, birthdate, and Social Security number

•   Mailing address and all contact information

•   What percentage you own of the business (anyone who owns 25% of the business or more will likely have to disclose personal details and identification)

•   A government-issued photo ID, such as driver’s license or passport

•   Business name and DBA (“doing business as” name) or trade name, if applicable

•   Business address and employer identification number (EIN) (Note: sometimes Social Security numbers suffice)

•   Industry/type of business

Depending on the type of business you own, you may be asked for the following documents:

•   Sole proprietorships may need the business name registration certificate and the business license.

•   Partnerships may need the partnership agreement, business name registration certificate, business license, and the state certificate of partnership.

•   Limited Liability Companies (LLCs) may need the articles of organization, LLC operating agreement, and business license.

•   Corporations may need articles of incorporation, corporate bylaws, and business licenses.

What to Look for in a Business Banking Account

Traditional banks, online banks, and credit unions all offer business bank accounts. All have different fee structures and provide different services. There are many fees and restrictions to consider when choosing a business banking account. But consider this overarching factor: online accounts are usually best for businesses that don’t need to make bank deposits.

Here’s what to compare when you’re looking for an account:

•   Monthly fees, such as account maintenance

•   Any minimum balance requirements

•   No-fee transactions

•   ATM access (for deposits and withdrawals)

•   Transfer, wiring, and payment capabilities

•   Incidental fees (such as, stop payment, overdraft, and nonsufficient funds)

•   Online and mobile banking tools

•   Additional features, such as invoicing, bill pay, or integrations with other business tools (especially tax reporting software)

Benefits of Opening a Business Banking Account

A business account can be a smart tool for a variety of reasons. Business owners may need to keep their personal and business accounts separate for tax and liability reasons. A business bank account also helps you establish a banking relationship that you can draw on in the future for lending or other services that may help your business grow. You will also establish a financial record that can come in handy when it comes time to file taxes and help your concern establish a good credit rating.

Cons of Opening a Business Banking Account

There are very few cases when a business banking account is a bad idea. Some very small sole proprietors may find they don’t need the extra fees and bookkeeping involved. But for most business owners, a separate account can be an efficient tool.

That said, one of the potential drawbacks of a business banking account is fees. High fees that you may not have anticipated can eat into your business profits. Some fees to look out for include monthly fees, transaction fees, monthly balance transfer fees, cash deposit fees, ATM fees, and wire transfer fees. These fees add up fast. Be sure to check thoroughly what fees are involved and compare from one financial institution to another.

Pros of a Business Bank Account

Cons of a Business Bank Account

Keeps professional finances separate from personal May involve additional fees
Establishes a business relationship with a financial institution May involve more bookkeeping
Creates a financial record that can be useful for tax or credit-rating purposes

Choosing a Business Bank Account

Now that you’ve looked at fees, here are some other considerations as you choose your business bank account:

•   Banking online: Business bank accounts with online-only banks can be great for virtual businesses or any business that is not handling daily cash transactions. Many online banks do not require a monthly minimum balance.

•   Network: If you’re banking in person, be sure there is a conveniently located branch near your business. Also, find out how many no-fee ATMs are available in your area.

•   Electronic services: Check if online bill pay, electronic fund transfers, and other electronic services that can support your business are available for low or no fees.

•   Electronic payments: Does your bank accept Zelle and Venmo? If so, are there additional fees involved? How long will it take for transactions to post? Electronic payments are increasingly becoming the lifeblood of many businesses.

•   Software compatibility: Is the bank account you’re considering compatible with the bookkeeping software you use? That can make life easier when you need to track or get access to cash flow, outstanding receivables, and other items each month.

Other support: Does the bank offer small business loans, lines of credit, business credit cards, and other financial support for entrepreneurs that you may need in the future?

SoFi members with direct deposit activity can earn 4.60% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a deposit to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate.

SoFi members with Qualifying Deposits can earn 4.60% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.60% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.

Interest rates are variable and subject to change at any time. These rates are current as of 10/24/2023. There is no minimum balance requirement. Additional information can be found at https://www.sofi.com/legal/banking-rate-sheet.


The following describes the terms that apply to participation in the SoFi Checking and Savings direct deposit promotion (the “Direct Deposit Promotion”) offered by SoFi Bank, N.A, Member FDIC (“SoFi”).

Eligible Participants: All new and existing members without any history of direct deposit transactions into their SoFi Checking and Savings account are eligible for the Direct Deposit Promotion. Members who previously enrolled in direct deposit into either SoFi Money or SoFi Checking and Savings, whether currently still enrolled or not, do not qualify for this Direct Deposit Promotion. Bonuses are limited to one per SoFi Checking and Savings account. In the case of a joint account, only the primary account holder (the member who signed up first) is eligible for a bonus.

Promotion Period: The Direct Deposit Promotion will begin on 01/01/2023 at 00:01AM ET and end on 12/31/23 at 11:59PM ET.

Bonus Terms: In order to qualify for eligibility for a bonus, SoFi must receive at least one Direct Deposit (as defined below) from an Eligible Participant before the end of the Promotion Period. Direct Deposits are defined as deposits of $1,000.00 or greater from an enrolled member’s employer, payroll, benefits provider, or government agency via ACH deposit. Deposits that are not from an employer, payroll, benefits provider, or government agency (such as check deposits; P2P transfers such as from PayPal or Venmo, etc.; merchant transactions such as from PayPal, Stripe, Square, etc.; and external bank ACH transfers not from employers) do not qualify for this Direct Deposit Promotion. The amount of the bonus, if any, will be calculated during the Direct Deposit Bonus Period as described and defined below.

Direct Deposit Bonus Period: The Direct Deposit Bonus Period begins when SoFi receives a Direct Deposit within the Promotion Period and ends 25 calendar days later (the “Direct Deposit Bonus Period”). For the avoidance of doubt, the Direct Deposit Bonus Period shall not extend beyond the Promotion Period. The bonus amount will vary based on the total amount of Direct Deposits received during the Direct Deposit Bonus Period. Once the Direct Deposit Bonus Period has elapsed, SoFi will determine if you have met the offer requirements and will deposit any earned bonus into your checking account within seven (7) business days. For example, if SoFi receives between $1,000.00 and $4,999.99 in Direct Deposits during the Direct Deposit Bonus Period, you will receive a one-time cash bonus of $50. A member may only qualify for one bonus tier and will not be eligible for future bonus payments if Direct Deposits subsequently increase after the Direct Deposit Bonus Period.

Total Direct Deposit Amount in Direct Deposit Bonus Period Cash Bonus Tier
$1,000.00 - $4,999.99 $50
$5,000.00 or more $250


Bonus Payment Timeline: SoFi will credit members who meet qualification criteria within seven (7) business days of the end of the Direct Deposit Bonus Period.

Bonuses are considered miscellaneous income and may be reportable to the IRS on Form 1099-MISC (or Form 1042-S, if applicable).

What Is Cryptography and How Does It Work?

What Is Cryptography and How Does It Work?

Cryptography is a science that has evolved over time since the ancient Egyptians used it to communicate. Today, it takes many forms, with quantum computer scientists just one group who uses this coded system. Throughout history and into the digital age, the purpose of cryptography has remained the same: It is a means to transmit data in a secure form so that only the recipient can access the information.

Modern cryptography is front and center in advancements in computer science and cryptocurrency ecosystems. Sophisticated encryption algorithms protect data, but the threat levels continue to rise as quantum computers offer a new arsenal to adversaries.

In this article, we’ll explore how cryptography originated, how it has transformed over time, and how it is applied in the world of cryptocurrencies. We’ll delve deep into:

•   Cryptography Definition

•   The History of Cryptography

•   How Cryptography Works

•   Cryptography and Cryptocurrencies

•   Cryptographic Algorithms

•   Cryptography and Quantum Computing

Cryptography Definition

Cryptography is a way to transmit information and data so that only the intended recipient can access it. The message, content, or data is encrypted by the sender and then decrypted by the receiver using codes or other methods.

In computer science, the process of encryption typically takes plaintext, or unencrypted text, and scrambles it into ciphertext. In the context of cryptocurrency, the cryptography definition is the process by which digital assets are transacted and verified without a trusted third party.

Cryptography is the technology that underpins cryptocurrency protocols. One large appeal of cryptocurrencies, such as Bitcoin (BTC) and Ethereum (ETH), is that transactions are anonymous.They occur on a secure, decentralized, peer-to-peer network without the need for a central authority, like a bank or financial institution.

Bank transactions rely on certain protocols and policies to protect transactions and reduce fraud: the signature on a check issued by a bank must be verifiable and counterfeit-proof (not forged), and the signer cannot later go back on the commitment the check represents. Cryptocurrency transactions rely on different protective measures: Cryptography and encryption keys allow cryptocurrencies to be traded without real-world signatures.

The History of Cryptography

Cryptography, derived from the Greek words “kryptos” (meaning hidden) and “graphein” (meaning to write), existed long before the digital age. The history of cryptography dates back to the year 1900 BC, with cryptographic symbols appearing in hieroglyphics found in tombs in ancient Egypt.

Later, around 40 BC, Julius Caesar encrypted messages using a system that became known as “Caesar’s cipher”. He used letter substitution to scramble a message so that only the person who knew the secret could unscramble the letters and read the text.

Giovan Battista Bellaso created the first encryption in the 16th century. It was called the Vigenere cipher (falsely attributed to diplomat Blaise de Vigenere), and featured a grid with the alphabet written across 26 rows. The written encryption matched the length of the message, and Bellaso used the grid to create the code to encrypt the message, letter by letter. The sender shared the secret key word and the encrypted message with the recipient, who possessed the same grid and could decode the message.

Modern computers have made encryption commonplace and much more sophisticated, but the intention is the same: to ensure that only intended parties can access the information.

How Cryptography Works

While cryptography methods have evolved from ancient times, the art has always served the same purposes: confidentiality, integrity, non-repudiation, and authentication.

•   Confidentiality ensures that only the intended recipient can access the information.

•   Integrity ensures that the data cannot be altered in transit or storage without the change being detected.

•   Non-repudiation ensures that the intentions of the sender of the information cannot be denied later.

•   Authentication ensures that the sender and receiver can confirm each other’s identity and the origin and destination of the information.

There are three forms of cryptography, each with different levels of sophistication for data protection: hash functions, asymmetric encryption, and symmetric encryption.

Hash Functions

Hash functions secure information using algorithms. Instead of using traditional keys, this approach relies on algorithms to turn data into a fixed-length string of characters. Hash functions are one-way encryption because it’s impossible to decode a hash into its original data.

Blockchain technology uses hash to encrypt large quantities of information without compromising the original data. Hashes create organized, structured, encrypted data that act like digital fingerprints. Any unauthorized modifications that may occur during transport through networks can be verified, and changes to the original data result in a new hash. That new hash would not match the original source and would not be verifiable on the blockchain.

SHA-1 (Secure Hash Algorithm 1), SHA-2, and SHA-3 are cryptography examples of hash functions.

Asymmetric Encryption

Asymmetric encryption, also known as public-key encryption, uses a pair of keys. One key is a public key that can be exchanged with anybody over any network. This key shows how to encrypt the data and anyone can access it. The second key is a private key. The private key explains how to decrypt the message, but only the private key holder has access.

Both keys are generated by an algorithm composed of large prime numbers to create two unique keys that are linked mathematically. Anyone with access to the public key can encrypt a message, but only the private key holder can decode the message.

Rivest-Shamir-Adleman (RSA) is an example of public-key cryptography and is typically used for VPNs, email, web browsers, and chat.

Symmetric Encryption

Symmetric encryption — also called secret-key encryption — relies on a single key. For symmetric encryption, the sender and receiver of the data share the same key used both to encrypt and decrypt the information.

To encrypt data, the secret key is agreed upon in advance. Because there is only one key, and one less layer of security, this level of encryption is riskier than symmetric encryption.

Advanced Encryption Standard (AES) is a cryptography example of symmetric and single-key encryption. AES was established in November 2001 by the National Institute of Standards and Technology (NIST). It is a Federal Information Processing Standard (FIPS 197) for encryption in the private sector mandated by the U.S. government.

Cryptography and Cryptocurrencies

Cryptography is what makes cryptocurrency appealing. Crypto transactions are encrypted as they travel across a blockchain and are both secure and transparent.

Bitcoin creator Satoshi Nakamoto devised blockchain technology to solve the “double-spend” problem, where the same currency unit could potentially be spent twice, and a currency’s value as an online payment solution would therefore be extinguished. Bitcoin’s time-stamped, peer-to-peer distributed ledger is secured cryptographically to prevent double-spending.

This was the beginning of blockchain technology and the evolution of the different types of cryptocurrencies we see today.

Cryptographic algorithms, also called ciphers, are used to code messages (like those from Julius Caesar and Giovan Battista Bellaso). Algorithms are derived from mathematical and rule-based calculations. The algorithms are used for keys, digital signing and verification, internet web browsing, confidential email, and secure credit transactions.

An algorithm or cipher suite (also known as a cryptosystem) uses one algorithm for encryption, a second for message authentication, and a third for key exchange.

Cryptography and Quantum Computing

Sophisticated algorithms are not impervious to hackers, and there is growing concern of the threat that quantum computing represents with powers to break current cryptography encryption standards.

The length of encryption keys is gradually increasing — as much as 256 bits (32 bytes) — and the algorithms are becoming more sophisticated in order to stop hackers from decoding them. But even the most complicated algorithms may be no match for quantum computers.

Quantum computing uses quantum bits (qubits) that can process an enormous number of potential results in parallel. These supercomputers can carry out integer factorization (breaking down large composite numbers into smaller numbers) at lightning speed, which is what makes current cryptographic algorithms so vulnerable.

The Future of Quantum Computers

Currently, the simple, small-scale quantum computers that have been created have had limited capabilities. But it may only be a matter of time before more powerful quantum computers are successfully developed.

Jason Soroko, CTO of PKI, Sectigo, explained it like this in an interview with EE Times : “A traditional binary computer solves that mathematical problem slowly, whereas a quantum computer with an efficient algorithm can solve that problem much more quickly. That efficient algorithm known as ‘Shor’s Algorithm’, when coupled with a quantum computer with enough stable qubits, will theoretically be able to break current cryptographic algorithms such as RSA and Elliptic Curve (ECC).”

Large-scale quantum computers are still a few years from existence, but the threat that these machines pose to symmetric algorithms like AES and asymmetric algorithms like RSA are real and causing NIST to seek more robust solutions.

The Takeaway

Cryptographic techniques are the cornerstone of the cryptocurrency market and the very reason market participation remains active. Encryption techniques ensure confidentiality, integrity, non-repudiation, and authentication — so that crypto transactions remain secure and anonymous.

Encryption techniques are growing ever-more sophisticated to combat cyber threats, and these threats are expected to intensify in the future with the development of quantum computers. However, focused scientific work is developing advanced algorithms to maintain protection even from the threat of quantum supercomputers.

FAQ

What is cryptography used for?

Cryptography is used for secure communications and as protection from adversarial third parties. In computer science, cryptography is a process of encryption using an algorithm and a key to transform an input (plaintext) into an encrypted output (ciphertext).

Cryptographic techniques allow cryptocurrencies to be traded anonymously. These techniques ensure confidentiality and that only the intended recipient can access information.They ensure integrity so that the data cannot be altered in transit and the intentions of the sender of the information cannot be denied later. Cryptography also allows the sender and receiver to confirm both each other’s identity and the origin and destination of the information.

How does cryptography relate to computer security?

Cryptography ensures secure computer networks and systems. The science of cryptography ensures the confidentiality of data, protects data from unauthorized modification during storage and transit, and allows data authentication.

How is cryptography used in the cryptocurrency space?

Three cryptography methods are used for cryptocurrencies: symmetric cryptography, asymmetric cryptography, and hashing. Symmetric cryptography uses a single key to encrypt the message at the source, transmit the encrypted message, and decrypt the message at the recipient’s destination. This method is simple to implement, but the shared key implies greater security risks.

Asymmetric cryptography uses two different keys — public and private — to encrypt and decrypt data. The public key — for example, the address of the receiver — is known openly, but the private key is known only to the receiver. The message can only be decrypted by the receiver’s private key. This method facilitates authentication and encryption for cryptocurrency transactions.

Hashing verifies the integrity of the data for network transactions by maintaining the structure of blockchain data. Hashes create organized, structured, encrypted data that resemble digital fingerprints. Any unauthorized modifications during transactions can be identified because they would create a new hash that would not match the original source and would not be verifiable on the blockchain.

Guide to World of Women NFTs

Non-fungible tokens (NFTs) are increasingly catching the attention of investors who are looking to step beyond simply buying cryptocurrency. Many different NFTs have gained the spotlight in the decentralized finance (DeFi) space, whether they represent art, music, or other types of collectibles.

The World of Women NFT collection, designed by a female artist with a female-centric focus, is built on the Ethereum blockchain. The goal of the project is to inject more diversity and inclusion into the cryptocurrency space.

Before investing in a World of Women NFT, there’s much to know about this ambitious project and the digital art it has inspired.

•   What is World of Women?

•   How Does World of Women Work?

•   World of Women Value

•   How to Buy World of Women NFTs

•   World of Women vs. CryptoPunks

What Is World of Women?

The World of Women NFT collection is made up of 10,000 NFTs developed by French artist Yam Karkai. In founding World of Women, along with co-founder BBA (an acronym for Being Bored Ape), Karkai sought to empower women and increase their representation in the NFT and cryptocurrency spaces. The NFTs launched on July 27, 2021, quickly selling out after catching the attention of several high-profile celebrities and influencers.

What Is an NFT?

But what does NFT mean, exactly? An NFT is a type of digital asset. NFTs use blockchain technology, the same technology that powers different types of cryptocurrency, to operate. NFT assets can be sold through peer-to-peer platforms and are typically associated with artwork or digital imagery, though a video or audio file could also be an NFT.

To date, the Securities and Exchange Commission (SEC) doesn’t have any standard guidelines in place for determining if and when an NFT is considered a security. As of January 2022, World of Women NFTs and other NFTs do not fall under any regulatory guidelines established by the SEC or the Financial Industry Regulatory Authority (FINRA).

How Does World of Women Work?

The 10,000 illustrations that make up the World of Women NFT collection were designed by Karkai using Procreate and Adobe Photoshop. Each NFT is a unique piece of art designed to represent an individual woman. When someone purchases a World of Women NFT, they’re purchasing a piece of digital artwork.

These NFTs are officially sold out, but can be bought and sold on the secondary market through the OpenSea platform. You’ll need a compatible cryptocurrency wallet and the required amount of Ethereum to complete the purchase of a World of Women NFT.

In addition to owning the digital artwork itself, World of Women NFTs allow owners to collect royalties for the commercial use of those images. Specifically, owners can receive 50% royalties for any profits associated with commercial use of the NFTs. World of Women does require NFT owners to agree to its licensing terms as a condition of earning royalties.

World of Women also sets itself apart in terms of how it reinvest profits. The company uses part of its earnings to fund women-centered projects around the world, such as Too Young to Wed , She’s the First , and Rockflower . This is all part of the company’s efforts to empower women while supporting art that’s designed to appeal to people of all backgrounds.

World of Women Value

When World of Women NFTs made their debut, they had a minting price of 0.07 ETH, which was equivalent to roughly $130 U.S. dollars. As of January 2022, the floor price (or starting price) for a single World of Women was 7.37 ETH. The average all-time price is 2.17 ETH, with trading volume hovering between 46,000 and 47,000 ETH.

At the lowest point, World of Women NFTs trade at 0.01 ETH. The highest sale price recorded to date is 260 ETH. That NFT, Woman #9248, sold for the equivalent of $587,269.80 USD. One of cheapest options is Woman #3556, which has a most recent sales price of 0.01 ETH or $22.47 in USD. Total trading volume is around $10.73 million.

So what determines how much a World of Women NFT is worth? Several factors related to the design of the image can influence pricing, including:

•   Background color

•   Clothing

•   Skin tone

•   Facial features

•   Accessories

The rarer or more unique an image is, the more it’s likely to sell for. That’s also the case with other image-based NFTs, such as CryptoPunks. These NFTs, which launched in 2017, have reached astronomical valuations as collectors seek out the rarest or most unusual images. CryptoPunk #7523, for example, sold for $11.75 million at a Sotheby’s auction.

How to Buy World of Women NFTs

If you’re interested in collecting NFTs from World of Women, you can purchase them through OpenSea, which is a secondary market for trading NFTs. To purchase World of Women NFTs, you’ll first need to connect or create a compatible cryptocurrency wallet. From there, you can use different filtering options to find NFTs to buy.

Filtering options include:

•   Price

•   Status (i.e., buy now, auction, etc.): An NFT that’s listed as “Buy Now” or “Make Offer,” would allow you to purchase it at that moment for the listed price or offer a different price to the seller. Ones that are listed as “Auction” will only allow you to place a bid.

•   Design (including backgrounds, facial features, etc.): The design filter feature can help you gauge an NFT’s rarity, as it breaks down what percentage of the NFTs share similar features.

The timing for completing the transaction can depend on which option you choose. It’s also important to keep in mind that demand on the Ethereum blockchain can slow down processing. OpenSea charges fees to use the platform. The fee is equal to 2.5% of every transaction processed.

World of Women vs CryptoPunks

World of Women is a newer NFT option, while CryptoPunks NFTs have been around for several years. In terms of valuation, the recent sale of CryptoPunk #7523 illustrates just how valuable a single CryptoPunk can be. Here’s a closer look at how World of Women and CryptoPunks compare.
