Hiron - Version 2.9.2.1 «Hiron» is designed to provide the highest-level, long-term security to personal information sent over email. The Project's goal is to assure a protection that could stand all kinds of feasible attacks by use of available computing facilities during decades to come,bearing in mind estimated technological progress. To achieve this goal, «Hiron» employs a sophisticated cryptographic system that involves a series of strongest known cryptographic algorithms (such as Rijndael, Twofish, ...) which 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.
