Crypto Composer is a crypto-system based on well published asymmetric public key and symmetric key crypto-algorithms. It is the first embodiment of our next generation soft token based declarative cryptographic key, access right and digital source distribution and management technology.

It can be used as a file/message encryptor/decryptor on local computer and in passing through the internet. It allows the public key authentication of the sender of secuured data and intended list of receivers so that a user can build his/her own dynamic virtual private network (VPN) over the public internet easily and automate it using our more advanced products and services.

It contains a personal crypto-gateway server and a (audio) media streaming server that provide modern cryptographic strength protection of a user's identity, privacy, (social) relationship, and rights on the internet.

The declarative, modern cryptographic security system of CryptoGateway allows fine grain person to person identity, privacy, access control, secured message exchange, and digital right management that is uncoupled to the hardware and software environments that they uses.
