A program to generate random reciprocal bigram tables
A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file.
Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed.
Executing the program with command-line arguments causes bigram to generate a random bigram table to...
ENIGMA 2000 is a reliable file encrypter for DOS shell
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...

A powerful Java-based command line shell and text console API. The text console uses Swing in order to be fully cross-platform and also provides for the use of native console APIs such as Curses and the Windows console.
cryptshell is a shell used for analysable code (eg anything before wwII). It automates letter substitution, transposition, and has modules useful for breaking various weak ciphers (enigma, substitution, vinigre). It has no real practical value.
