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 ...

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 ...

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 ...

Abstract: For increasing attackers and their risks in life, the two parties (sender and receiver) can be using a safe environment to send and receive the secret message by encrypting the message ...
