An educational tool for studying classical cryptography schemes. Do not encrypt anything of worth with this library.

Included Ciphers:

Caesar
Affine (Linear)
Substitution
Stream
Vigenere
Enigma (Wehrmacht Enigma I)

Thanks to polymorphism, we can generate keys and encrypt ByteStrings without worrying much about types:

> import Crypto.Classical
> import Lens.Micro
> :set -XOverloadedStrings
> (\k -> encrypt k "What a great day for an attack!" ^. enigma) . key <$> prng
"PXQS D KXSGB CFC AYK XJ DEGMON!"
> (\k -> encrypt k "What a great day for an attack!" ^. caesar) . key <$> prng
"RCVO V BMZVO YVT AJM VI VOOVXF!"
