This program is an implementation of the Mini-AES published in Cryptologia by Raphael Chung-Wei Phan in 2002.

Mini-AES has parameters significantly reduced while preserving its original structure. It is meant to be a purely educational cipher and is not secure for actual applications. Mini-AES encrypts files in blocks of 16 bits (2 bytes) and the secret key has the same size.
