AES uses the same secret key is used for the both encryption and decryption. Unlike AES 128 bit encryption and decryption, if we need a stronger AES 256 bit key, we need to have Java cryptography extension (JCE) unlimited strength jurisdiction policy files. 1. AES – Advanced Encryption Standard. AES is a symmetric encryption algorithm. It was intended to be easy to implement in hardware and software, as well as in restricted environments and offer good defenses against various attack techniques. AES is block cipher capable of handling 128 bit blocks, using keys sized at 128, 192, and 256 bits.
