Until now, no such integrated system exists ! The market offers mainly two cryptographic algorithms that are included in several non-integrated applications :
(secret encryption algorithms that the international scientific community cannot evaluate and compare, are excluded ; these secret algorithms will never be accepted as an international solution...)
The DES algorithm is old and, with current technology, an exhaustive key search is quiet easy and feasible. This algorithm will certainly be abandoned in the near future after more than 20 years of good service, no company should base its new applications on it...
One of the major advantages of the RSA algorithm is also one of it's major disadvantages : a message can only be decrypted by someone owning the associated key. So, when defending our Democracies against terrorism and serious crime, the different National Security Services are not able to decipher suspect messages. This is contravenes OECD and most other countries policy. Unless you deposit a key....
