HcryptoJ

HcryptoJ (Historical cryptology in Java) is a Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science. Licensed under GPL.

Features

Extensible object-oriented design modeled after the Java Cryptography Extension (JCE).
General enough to implement any symmetrical key cipher that maps plaintext to ciphertext.
Supports encryption, decryption, and analysis of strings and ASCII files.
Default Provider classes are supplied which contain implementations of Caesar, Simple Substitution (passphrase), Vigenere, Playfair, Affine, RailFence, and Transposition ciphers.
All Cipher objects are defined with a Key class which can accomodate a wide range of key types.
Supports a wide range of alphabets including: az, AZ, azAZ, azAZ09, printable ASCII and the full ASCII character set.

The most invaluable part, the CryptoGram Analyzer, is just skeleton code (function/interface definitions) with no actual working code behind them.
