Actually if you do it properly this kind of encryption is unbreakable, but you'd have to: 1. generate a random key long enough to cover your data 2. keep the key secure and in a separate place 3. DON'T use the key twice there must be a Security Now episode that explains the thing pretty well (could be this one http://www.grc.com/sn/sn-011.htm). Some arguments may rise against the randomness of the key, but I don't think its the case to go into that. You could also use TrueCrypt which is an extremely powerful cryptographic software (open source), I found this article that can help you linking it with python: http://blog.bjrn.se/2008/01/truecrypt-explained.html _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
