| The RSA algorithm was patented until September 2000 when RSA® Security Inc. released the algorithm into the public domain. "BEDFORD, Mass., September 6, 2000 -- RSA® Security Inc. (NASDAQ: RSAS) today announced it has released the RSA public key encryption algorithm into the public domain, allowing anyone to create products that incorporate their own implementation of the algorithm."

| The Twofish block cipher by Counterpane Labs was developed and analyzed by Bruce Schneier, John Kelsey, Doug Whiting, David Wagner, Chris Hall and Niels Ferguson. Twofish was one of the five Advanced Encryption Standard finalists. At the time of writing the Twofish homepage can be found at http://www.counterpane.com/twofish.html. The cipher has been made available to the general public by the following statement on http://www.counterpane.com/about-twofish.html :
|
| " Twofish is unpatented, and the source code is uncopyrighted and license-free; it is free for all uses. Everyone is welcome to download Twofish and use it in their application. There are no rules about use, although I would appreciate being notified of any commercial applications using the algorithm so that I can list them on this website. "
