AES Algorithm. The AES algorithm is an iterative, symmetric-key block cipher that supports cryptographic keys (secret keys) of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. We are using KeyGenerator Class to generate symmetric encryption keys, we get the KeyGenerator instance by calling the getInstance () method passing the name of the algorithm as a parameter, in our case it is AES. KeyGenerator keyGenerator = KeyGenerator.getInstance ("AES"); Cipher cipher = Cipher.getInstance ("AES/CBC/PKCS5Padding"); Cipher name is composed of 3 parts.
