A Python-based implementation of Row and Column Transposition Ciphers for text encryption and decryption. Features an interactive CLI interface, support for custom keys, and automated padding handling ...

The hybrid cipher presented in this report integrates AES encryption with a columnar transposition technique, creating a secure and efficient encryption system. This combination leverages both ...

Abstract: The idea behind this paper describes a modality about secret interface over the globalization of the communication over the world. To accomplish this phenomenon, two varieties of security ...

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 ...

Abstract: This paper aims to secure visual information present in an image using cryptographic techniques. Transposition cipher and Bit reversal image encryption are the two techniques demonstrated in ...

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 ...

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, ...
