HcryptoJ Description

Library for implementing and analyzing historical ciphers HcryptoJ (Historical cryptology in Java) is a free and open source Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science.HcryptoJ is suitable for use by novice and intermediate level Java programmers as well as by nonprogrammers and has been used in a variety of undergraduate research and teaching projects. HcryptoJ is general enough to implement any symmetric key cipher system that translates plaintext strings into ciphertext strings and vice versa. Here are some key features of "HcryptoJ": · 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. Requirements: · Java
