## Detailed Description

Interface for Restricted Identification.

Restricted Identification is a protocol to generate pseudonym identifier based on key agreement protocol. The protocol use a secret key of an asymetric key pair and the public key of a second asymetric key pair. For every two diffrent secret keys with same public key the identifier is diffrent. For any two diffrent public keys it is computational infeasible to link two identifiers with the same secret key.
