Encrypting or decrypting a message or a string is supported by Java Cryptographic Extension (JCE) framework in Java.Using the AES encryption algorithm, a plain text message is converted into a cipher text with the help of a secret key that is only known to the sender and receiver of the message.AES can be difficult to implement with the software.Each block is encrypted using a similar kind of encryption.

AES algorithm uses very simple algebraic formulae.

The companies who want to transfer their data safely and without breaking it can always use the AES algorithm.

AES is the most common security algorithm used worldwide for various purposes like wireless communication, financial transactions, encrypted data storage, etc.

The encrypted data cannot be decrypted without a valid secret key.The original data value is encrypted using different bits of padding such as 128, 192, or 256 bits. It means that the data to be encrypted is converted into blocks for encryption. It uses a valid and similar secret key for both encryption and decryption. It works with key size 128, 192, and 256 bits. It is a type of symmetric, block cipher encryption and decryption algorithm. What is AES?ĪES is an Advanced Encryption Standard algorithm.

In this section, we will discuss the AES 256 encryption algorithm and implement the logic in a Java program. Java programming provides security for data transfer as well as communication between several nodes by supporting different encryption and hashing algorithms. Security has become an important aspect nowadays.
