Cypher-Decypher

Ever since I was a little kid, I’ve always been enthralled by puzzles; be it the Sudokus featured daily in newspapers, or the multitude of brain teaser apps that came and went on my phone.

My favourite puzzle, however, will always be decoding little cyphers. I love the idea of sending encrypted messages, and decoding them.

Aim:

The project aims to both encrypt and decrypt messages, by using a variety of methods.

Progress:

The cyphers implemented include:

• Additive Cypher
• Multiplicative Cypher
• Hill Digraph Cypher

Features To Work On:

• Add more mathematically complex cyphers
• Implement fuzzy matching to find keywords
• Use concepts of relative frequency to match more efficiently to answers
• Improve design (css) of page
• Add feature for user management - Similar to a password keeper

Technology Used:

• Python for the functions which encode/decode the text
• Flask Framework

Deployment:

The app has been successfully deployed here.
