Detailed Description

Public Domain AES encryption/decryption rewritten.

The Rijndael encryption algorithm has been designed to replace the aging DES algorithm. Like DES, it is a block cipher. It uses 128-bit, 192-bit or 256-bit keys. This implementation encrypts 128-bit blocks. (DES used 56-bit keys and 64-bit blocks.)

The code in this package is a modified version of an implementation placed in the public domain by the following persons:

• Vincent Rijmen vince.nosp@m.nt.r.nosp@m.ijmen.nosp@m.@esa.nosp@m.t.kul.nosp@m.euve.nosp@m.n.ac..nosp@m.be
