WebbAES uses 128-, 192- or 256-bit keys to encrypt and decrypt data. The AES encryption algorithm defines numerous transformations that are to be performed on data stored in an array. The first step of the cipher is to put the data into an array, after which the cipher transformations are repeated over multiple encryption rounds. http://www.trytoprogram.com/c-examples/c-program-to-encrypt-and-decrypt-string/
