Introduction to Cryptography: Slides (PPTX)

jeffersonwheel/substitution.py - simple monoalphabetic substitution cipher
jeffersonwheel/jeffersonwheel.py - code for Jefferson's Wheel Cypher

The wheelcypher.pptx is a PowerPoint file with a generated wheel key that can be printed on a double-sided printer and cut into rings that fit around a water bottle to make a model wheel cipher machine.

Visual Cryptography and Perfect Ciphers

visualcrypto/explanation.pptx - shows the two different ways to encode each bit.

visualcrypto/visualcrypto.py - Python code for generating keys and transparencies. See the comments in the code for how to use.
