Vigenère

Vigenère is a program for encrypting and decrypting text using the Vigenère cipher. Built-in cryptanalysis tools make it possible to crack the cipher without needing the key — or even knowing its length.

Features

• Encrypting text with a key
• Decrypting the cipher with a key
• Decrypting the cipher without a key (cipher cracking)
• The program works with any alphabet, allowing you to manually input a custom one. English and Russian alphabets are built-in by default.
• Advanced cryptanalysis tools
• Supports loading frequency tables from a file. It is possible to modify frequency tables and save them. The program comes with built-in frequency tables for English and Russian letters.
