RPK's core technology, the patented RPK Encryptonite Engine, is an exceptionally fast public key algorithm for encryption, authentication and digital signatures. It offers a unique combination of the benefits of public key systems and the high performance characteristics of symmetric or "secret key" systems. RPK Encryptonite is available as a software toolkit or a high speed ASIC capable of large key encryption speeds of up to 100 megabits per second. Applications include streaming video and audio narrowcasting, secure cellular and satellite telephones, and VPN implementation. Developed outside of the U.S., the RPK Encryptonite Engine is available globally with strong encryption, unlike competing products that are restricted by U.S. export regulations.
