Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.
JCrypTool moved to GitHub! See https://groups.google.com/d/topic/jcryptool-developers/nauEXL6vsbk/discussion for more information and visit our new project home at https://github.com/jcryptool
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
NAC is a collection of tools for cryptography. The goal is to provide simple-to-use crypto tools (like an OTP, String and number generator, public key algorithm...) you can use under Linux, Windows...
