DES 64-bit encryption

Date: 2011
Purpose: Extension from class project
Technologies involved: PHP, CSS, HTML.
URL: http://mavroudisv.eu/des

Info: Implementation of DES algorithm using php. None of the php crypt libraries was used. It encrypts up to 64 bits bit streams and pads with zeros (0) if needed. I followed this tutorial and each separate step is commented in the source code. Also, some examples (plaintext/key/cipher) and useful links for further research are provided. [Source code]

TODO: 1) Add decryption functionality. 2) Step by step execution.
