Class TcBasicCrypto

java.lang.Object
  iaik.tc.tss.impl.csp.TcBasicCrypto

Direct Known Subclasses:

TcCrypto

public class TcBasicCrypto
extends java.lang.Object

This class is the CSP (crypto service provider) of the TSS. That means that all cryptographic functionality required by the TSS is centralized in this class. The intention is to make porting to different crypto libraries as simple as possible. To allow compilation of the API definition (without implementation) (i.e. for Wrapper translation with GCJ), the TcCrypto class has been split in a basic part, and a full implementation that extends it. TcBasicCrypto is compatible with GCJ.
