Operation

create(cipher).encode(text, options): the text through one cipher, options by name.

Input

letters

A chip loads the cipher with a sample sentence and options that work, so the fastest way to see an error is to load one and break a key.

CLI 

$ ciphers encode vigenere 'ATTACK AT DAWN' --key LEMON
