The most important distinguishing feature of Hiron resides in its sophisticated cryptographic system of unparalleled strength. It is designed to provide the highest-level, long-term security to personal information sent over e-mail. 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 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.

When we send an email, we have to be aware of the fact that our message can easily be read:

By most anyone who works for our Internet Service Provider.
By most anyone who works for the recipient's Internet Service Provider.
By anyone who operates any of the perhaps dozens of Internet routers that your data packets will pass through.
By anyone with physical access to the telephone switching equipment in the phone company's office

In addition, the Hiron application involves:

Unique encoding scheme
Protection against disassembling, decompiling, debugging, reverse engineering, or tracing the application's normal functioning
Ability to handle documents without leaving any trace of their unencrypted forms on data storage media
Simplicity in sending a document, either encrypted or not, by email: a single click on a toolbar button does the job.

The application was designed and implemented by a professional theoretical physicist, who also is an experienced cryptography programmer
