Crate cipher_crypt

A cryptographic tomb of ciphers forgotten by time.

There's a reason these archaic methods are no longer used - its because they are extremely easy to crack! Intended for learning purposes only, these ciphers should not be used to encrypt data of any real value.

Modules

caesar	The Caesar cipher is named after Julius Caesar, who used it (allegedy) with a shift of three to protect messages of military significance.
railfence	The Railfence Cipher is a transposition cipher. It has a very low keyspace and is therefore incredibly insecure.
rot13	ROT13 ("rotate by 13 places"), is a simple implementation of the Caesar cipher. It substitutes a letter with the one 13 places after it in the alphabet.
vigenere	The Vigenère Cipher is a polyalphabetic substitution cipher. It was considered 'le chiffre indéchiffrable' for 300 years until Friedrich Kasiski broke it in 1863.
