🥗 Caesar Decipherer

No need to know the key!

A Caesar cipher decipherer where the key and the deciphered message are automatically calculated (see below for how it works)

How It Works

This command-line Python decipherer uses natural language processing to automatically decrypt encrypted messages without requiring a key input.

By analyzing the ciphertext and leveraging linguistic and letter patterns (frequently used words and average letter distributions), the program determines the most probable decryption key and produces the corresponding plaintext.

ToDo

Add support for spaceless encrypted messages
Add support for more languages (suggestions are welcome!)
~~Optimize using letter distribution~~

Limitations

The program currently only supports uppercase and lowercase letters of the English alphabet. Other characters will be left unchanged.
