CRYPTOGRAPHY

This directory contains simple implementations of some of the main cryptography algorithms.

I will add the algorithms as I code them.

NOTE: These cryptographic implementations are just 'educational' implementations to show and understand how the algorithms work, but should not be used in 'serious' cryptographic environments, as these implementations could be subject to simple attacks (which I may code as well.. - e.g. timing attack on DES, attack on RC4..).

Data Encryption Standard - DES

Well-known symetric-key block cipher.

Diffie-Hellman Key Exchange

Key exchange which can be used in IPsec, the TLS handshake and more.

Feistel Cipher

Block cipher used in other algorithms such as DES.

RC4

Stream cipher used in WPA, WEP, TLS/SSL, Remote Desktop, ...

Vigenere and Ceasar Ciphers

Elementary and easy-to-use ciphers.
