A C++ cryptography toolkit implementing Caesar and Vigenère ciphers with brute-force and frequency analysis for learning classical encryption techniques.
CipherTool is a modular C++ application that demonstrates the implementation of classical cryptographic algorithms and introductory cryptanalysis techniques. Designed as an educational project, it provides an interactive command-line interface for encrypting, decrypting, and analyzing text using well-known historical ciphers.
The project currently supports Caesar Cipher and Vigenère Cipher, along with brute-force decryption and frequency analysis to illustrate how classical encryption methods can be attacked. The codebase emphasizes clean function decomposition, readability, and maintainability, making it suitable for students exploring data manipulation, string processing, and software design principles in C++.
