Hiron is designed to provide the highest-level, long-term security to personal information sent over e-mail. The project's goal is to assure the level of protection that could stand all kinds of feasible attacks by use of available computing facilities during decades to come, bearing in mind the estimated progress in technology and cryptanalysis. To achieve this goal, Hiron employs a sophisticated cryptographic system that involves a series of strongest known cryptographic algorithms (such as Rijndael, Twofish, ...) which, on being properly tuned, are incorporated as building-blocks within an innovative encryption technology. A higher-order elliptic curve is used for asymmetric (public key) encryption. The program was designed and implemented by a professional theoretical physicist who also is an experienced cryptography programmer.
