Collection of Classical Ciphers

Cryptographic algorithms and attacks in Java 8

This project implements the Playfair Cipher in Java, a classical encryption algorithm that secures text using a 5x5 matrix generated from a keyword. It provides functionality to encrypt a message, save it to a file, and later decrypt it back to its original form.

Cipher's Algorithms are basically techniques for encrypting data in a different ways

this is just a hands on learning and flexing of basic cryptography codes using java

Codes for my Computer Systems Security study on various encryption algorithms.

"🔐 My crypto algorithm implementations from class assignments - classic encryption methods coded from scratch. Academic projects turned learning playground! Hope these help fellow CS students survive their cryptography courses 💻✏️"
