Re: Had to happen someday, right ?

It has long been said that if your encryption scheme is correct, it doesn't matter if everyone knows how it works because that knowledge gives you no leverage in discovering what was encrypted without having the keys that were used.

Yes, it's called Kerckhoffs' principle (Wikipedia insists on adding a further "s" to this - it appears I learned grammar for a different version of English), although I also like Claude Shannon's related maxim "the enemy knows the system".

As a slight aside, I think it was necessary for Kerkhoffs to write in French despite being Dutch. For many, an article in Dutch would already look like it was encrypted :)
