Here's something you might find useful they've just started a series
on cryptography on this site, you can read them or listen to a
podcast.

Hi Matthew,
Counterpoint: think of "one-time pads".

Yes - at the moment this is just a way

That's really useful, thanks, as I was planning to iterate over each

The xor bitwise operator works wi
Hello,
I'm trying to work on some programs to help me understand ciphers and
ultimately cryptography. I've understood so far, that a simple form
of bit-level cryptography is to split the original message into chunks
the same length as a 'key' and then do an xor. I'm trying to keep
