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.
