##Intro Crypto ###Basic Cryptography Examples and Work

This repo contains the working code for fairly elementary cryptographic cipher work.

It started as a learning game experiment which was intended as a basic substitution
cipher. It has since been expanded to include character frequency analysis and polyalphabetic
cipher encryption & decryption.

Some of the methods are expository, such as encrypt_single, as well as the reverse
(decrypt_single). They were created to act as stand alone code snippets to augment
a series of blog entries I am making on the subject.

Topics covered to date :

• Caesar Cipher / Basic Substitution Cipehr
• Polyalphabetic Cipher
• Character Frequency Analysis
  • Generates frequency report on string
  • Determines substitution padding based on letter frequency
  • "Decode" method to automate iterating through offsets until detected language matches English
