You can do this by hand. But don't: write code to do it for you. How? Devise some method for "scoring" a piece of English plaintext. Character frequency is a good metric. Evaluate each output and choose the one with the best score.
WebGreat answer. I personally would go with Python: it just makes things easier and you can focus on the cryptanalysis concepts. As for how things are implemented, that's a huge separate exercise in itself. Ruby should be fine too, but honestly, investing a little bit of effort in learning python is well worth the effort! WebNov 14, 2015 · Python has native support for both HEX and base64 encoding: import base64 def main (): b16 = bytearray ('10000000000002ae'.decode ('hex')) b64 = base64.b64encode (b16) print b64 Share Improve this answer Follow answered Apr 16, 2024 at 8:56 Helton Wernik 165 1 3 Add a comment
WebAlso this is the perfect opportunity to use the yield keyword in Python that allows to easily create "generators", i.e. objects that can be called several times and keep a state between two calls.
