Is the encryption algorithm published ?
The Public Key Cryptography RSA algorithm we use is an international specification.The PTP Symmetric algorithm uses techniques standard in the industry: Substitution, Permutation, Multiple Rounds, Cypher Block Chaining, Initialisation Vector.The Copyright for this algorithm was time-lined in 1985. It is not published because there is no intention of inter-operating with any party outside PTP. Another strong reason is that it presents another barrier in the security defense, not least involving reverse-engineering of the software, a significant additional barrier.
