We all have secrets to keep. Those secrets could be personal dirt we want to keep from others, or they could be something as mundane as our credit card numbers or medical histories. But all of us have ...

This project demonstrates the implementation of the Columnar Transposition Cipher, a classical encryption technique that rearranges characters of the plaintext using a numerical key. It also includes ...

However, Agent Madeleine numbered the duplicate A's and L's from right to left instead of from left to right, so it would be the equivalent of replacing the keys with MCHBTUNDILA and CUMLBTJNDIKA, ...

This Streamlit app demonstrates an encryption technique based on the Irregular Rectangle Transposition Cipher, a modified form of columnar transposition where each row begins filling from a different ...

The keys are correct as stated, but instead of numbering duplicate letters from left to right, Agent Madeleine numbered them from right to left. You may want to complete the decryption yourself before ...

It’s been a couple of Math Mondays since we last looked at columnar transposition ciphers, so let’s jump back in. In the It’s been a couple of Math Mondays since we last looked at columnar ...
