This article and this article provide a basis of critique for people using 14 letter passwords in rc5 and assuming some sense of security. Hint is… it is not secure. It is not as bad as Microsoft using rot13, but it is close. Computing power and memory win against encryption. Given extensible memory and speed, password and/or public/private key hacks can be managed the same way. granted it would take a ton of resources to build the massively parallel computer that could do such a key shuffle, but it is theoretically conceivable and likely from my sources already existing. Now granted, what one can do in a small black-hat setup is fairly limited in terms of 1024 encryption, and most people scoff at the resources required to do a large shuffle.
