feat: DES encryption #101

Closed lonerapier closed 3 months ago

lonerapier commented 3 months ago

This PR fixes/closes issue #100

It changes the following:

adds DES symmetric encryption algorithm
demonstrates various attacks possible:
- known plaintext attack
- weak key attack
- bit complements

lonerapier commented 3 months ago

@Autoparallel added a SymmetricEncryption trait that I think is general enough for now (will work with DES, AES), and we can iterate later if we decide to add new encryption functions in future

wdyt? can it be improved further?
