AES performs its calculations in the form of byte data instead of bit data. It consists of multiple texts to produce a ciphertext. This algorithm uses substitution and permutations known as the SP networks.
Java development environment, that is, IntelliJ IDEA.ĪES is a 128-bit symmetric block ciphertext. Table of contentsįor a better understanding of this article, you will need: We will also discuss how this algorithm can be implemented using the Java programming language. AES, Advanced Encryption Standard is a block ciphertext encryption and decryption algorithm that processes a block of 128 bits of data using secret keys of 128, 192, or 256 bits. In this article, we will look at AES as a method of data encryption and decryption. 
There are various methods used to encrypt and decrypt data to enhance the safety of data transmitted.
Data encryption is an important feature in data protection.
