enervige
A statistical tool to break the Vigenere cipher
Enervige is a Python-based project for encryption, decryption, and cryptanalysis of text using the Caesar and Vigenère ciphers in French and English. The project includes advanced statistical techniques to break the Vigenère cipher using methods like frequency analysis, mutual index of coincidence (ICM), and Pearson's coefficient of correlation. -
