decode a vigenere ciphertext without having the keytext
807607Nov 24 2006 — edited Nov 24 2006hello,
I have to write a code that kann break a vigenere cypher:
I have a cyphertext :NIFJEHF
and i have to find the keytext to decrypt the cyphertext.
Can Anybody help me please or tell me how to proceed?
I already google but didn't find nothing helping me to program that.
Thank for your help
