Transposition Cipher

ccrypt is a utility for encrypting and decrypting files and streams. It was designed as a replacement for the standard unix crypt utility, which is notorious for using a very weak encryption algorithm. ccrypt is based on the Rijndael cipher, which is the U.S. government's chosen candidate for the...

DP-Multicrypt is a filecrypther with drag and drop support: Multicrypt might the following cipher: Blowfish, Cast256, IDEA, Mars, RC4, Twofish, RC6, Rijndael with the full keysize from this cipher and the CBC-MODE. DP-Multicrypt crypt with the full keysize from this crypter: Blowfish cipher use...

Cryptographic Text Converter is a small, easy to use application specially designed to offer you a graphical text editor that allows users to encrypt / decrypt the textual contents displayed on the screen using a 128-bit AES (Advanced Encryption Standard) cipher. for WindowsAll


Platforms: Windows

Hide your valuable information from unauthorized access. Use this easy software for encoding images and hiding valuable textual info into the image (steganographie). Several encrypted images together with hidden text could be saved into one file.

ARaC (Almost Random Cipher) is (or will become) a 512bit cipher. The ARaC suite is a C program which can encrypt/decrypt files and streams. The cipher itself cannot be download on SF due to US export laws, check http://arac-suite.sourceforge.net !


Platforms: Windows, Mac, BSD, Solaris, Linux

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.


Platforms: Windows, Mac, Linux

Ganza is a cryptanalysis tool for classical ciphers (mono and polyalphabetic) that lets the user define almost completely arbitrary cipher and plain alphabets, allowing for the proper cryptanalysis of cryptograms obtained from non-English texts.


Platforms: Windows, Mac, Linux

JEnigma is a java API to implement the Enigma cipher, as used by the Enigma encryption machine.

OpenSEED is open source implementation for SEED, the 128-bit Symmetric Block Cipher which is used widely among Korean Financial & Banking Companies. OpenSEED will implement TLS over SEED, also.


Platforms: Mac

A command-line to help encipher and decipher your password based on a simple algorithm. Java version provides GUI.


Platforms: Windows, Mac, Linux

This collection of tools helps cracking texts encrypted with monoalphabetic substitution: 1) Gathering statistics of a certain language, 2) creating keys, 3) encrypting and decrypting texts, 4) cracking texts automatically, 5) fine-tuning of decryption
