Practical One Time Pad  
   This system is designed for the requirements of the undercover agents working in foreign countries, but may be extended to be used for the personnel of embassies and consulates. Instead of exchanging messy OTP's, some neatly prepared simple and sho

Warlock Cipher  
   Warlock is a stream cipher that uses a key as long or longer then the plain text, where the key is derived from the Password and SHA-512 recursion) to cipher the data, followed by a Clear-Text transform to disguise the encrypted data from triggering any s

MAG Random Number Algorithm  
   MAG is an algorithm (cellular automata) that creates an apparently random stream of numbers. It is very simple and very fast.There are arguments that the MAG algorithm can be easily transformed in the NP class of problems which enables a complexity-theore

SC128 block cipher  
   SC128 is a new block cipher whose design is quite original. It is very efficient in all environments, and is fast in software (6.5 cycles per byte with MMX instructions). The site contains a PDF document, a source code, and a sample of statistical tests (
