With all the talk of data breaches, cyberattacks, and ransomware, it’s no wonder people are looking for ways to secure their information. One popular way to do this is by using encryption algorithms – software that can scramble your data in such a way that only you and whoever you choose can decrypt it. In this article, we’ll take a look at the nine most popular encryption algorithms and see which is the best for you.

## What is an Encryption Algorithm?

An encryption algorithm is a mathematical formula used to transform readable information into an unreadable format. The most common types of encryption algorithms are symmetric-key and asymmetric-key algorithms. Symmetric-key algorithms use the same key to encrypt and decrypt data, while asymmetric-key algorithms use two different keys.

## Types of Encryption Algorithms

There are many different encryption algorithms, each with its own set of benefits and drawbacks. The two most common types of encryption algorithms are symmetric-key and asymmetric-key.

Symmetric-key algorithms use the same key to encrypt and decrypt data. This makes the algorithm vulnerable to attack if the key is stolen. As a result, symmetric-key algorithms are usually used only for small amounts of data.

Asymmetric-key algorithms use two different keys: a public key and a private key. The public key can be shared freely, while the private key is kept secret. Data is encrypted using the private key, then encrypted again using the public key. This method provides greater security because it is difficult to decrypt data without knowing the private key.

There are many different types of asymmetric-key algorithms, but two of the most common are RSA and ECC.

## How Do Encryption Algorithms Work?

Encryption algorithms are used to protect data from unauthorized access. They work by transforming readable data into an unreadable format. This process is called encryption. The most common type of encryption is the use of a code. When data is encrypted, it is transformed into a series of unintelligible symbols or numbers. This code can then be used to protect the data from those who do not have the correct key.

There are a variety of encryption algorithms available, but the two most popular are symmetric-key and asymmetric-key algorithms. Symmetric-key algorithms use the same key to encrypt and decrypt data. As a result, if someone knows the key, they can decrypt the data. Asymmetric-key algorithms use two different keys – one for encryption and one for decryption – which makes it more difficult for someone to decrypt the data.

## The Five Latest Encryption Algorithms

The five latest encryption algorithms are: AES-256, SHA-384, SHA-512, DRBG and Curve25519. AES-256 is the most recent algorithm and is considered to be the strongest encryption algorithm.

## Conclusion

In this article, we will be looking at the latest encryption algorithm – AES-256. AES is a symmetric-key block cipher first proposed in 1987 by David Chaum and Serge Vaudenay. It uses 256 bits of internal state (i.e. key), and operates on blocks of 64 bits. The cipher has been adopted as the standard for most industrial applications that require high levels of data security, such as banking and e-commerce.
