EnigmaLike is an Enigma-like encoding tool for text files that encodes word-by-word using a dictionary/code book/encryption reel set-up. EnigmaLike is written using PerlTk and has instructions in PDF format. For Linux.

Released under 'Creative Commons v3' license Alien Cipher is an endeavour to build my own symmetric cipher. The primary aim is to simply learn the fundamentals and finer details of cryptography in general and build working examples of my ideas in code. The code is shared here for posterity (future folk) in the guise that it may help others also on the path to cryptography. This code demo uses a 256bit rolling hash table (8x8bytes) at its heart to mix together pre-defined parameters in a way that allows the cipher to produce encoded output that is locked to a key of arbitrary length without padding. ...

...MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only 5 lines of code: Ten arithmetic and bitwise operations in all. It's called MOTE because a PRNG can't be made much smaller (or faster) without introducing bias or severely reducing avalanche. MOTE alternates its shift and rotation constants unpredictably, and has passed the most stringent industry-standard tests for randomness and security, including NIST & DIEHARD.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code.
