Ha ha, that's funny! I've never heard that one before! *wink* I may add a quadruple-rot13 to the next release. Would you like credit? obfuscate does include ciphers which, prior to the invention of the computer, were good enough for real world use. E.g. the Playfair cipher was still in use for field communications in World War 2, e.g: http://practicalcryptography.com/ciphers/playfair-cipher/ and of course Vigenere is uncrackable if you provide it with a cryptographically random key as long as the message which you use only once. (In that case, it is a one-time-pad.) -- Steven -- http://mail.python.org/mailman/listinfo/python-list
