Collection of '30' cryptography ciphers coded in JavaScript and an interface coded in HTML styled with CSS.

Python-based CustomTkinter GUI toolkit for learning classical cryptography. Implements Caesar, Playfair, Rail Fence, and Row-Column ciphers with brute-force attack modules. Educational, modular, and fully offline.

Python-based command-line toolkit for classical encryption and cryptanalysis, featuring modular cipher implementations and attack utilities.

Kryptos K4 — DECODED. 36 years unsolved. 97 characters. 47 phases. The CIA's courtyard cipher — cracked. Forward encryption proof: 97/97 match, zero conflicts.

Explore classic and modern encryption methods with the Cryptography Toolbox. This open-source project offers a simple command-line interface for six encryption techniques, including Caesar Cipher and Vigenere Cipher. Ideal for learning and experimenting with cryptography.
