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.

...Either sox or audacity can easily transform to this format. The wav file is expected to be international morse code, preferrably clean and properly spaced. Tonal frequency or wpm-speed does not seem to matter. Now includes an inverse commandline app, txt2wav that creates a morse code WAV file from English text. The proper command to extract the archive and maintain the directory structure is "7z x filename".

ENIGMA 2000 is a symmetric cryptographic algorithm developed in C++ for Windows, to encrypt any file. It is not optimized for speed processing but it is extremly reliable. Tests state that a huge input file just with zeros, will return an output file whose frequency analysis is white noise. It uses six phases to encrypt any file and the phases sequence depends on the password. On phase 5, it uses the Rubik's cube paradigm to encrypt the data. It's extremly reliable and the password varies between 8 and 16 characters. The execution syntax is: coder.exe [file to encode] [password (min 8 char, max 16)] [mode ('c'oder 'd'ecoder)] Enjoy it

Alkindus is an automated solver for short monoalphabetic substitution ciphers without word divisions.

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm
