Class SkeinParameterSpec

java.lang.Object
  |
  +--org.bouncycastle.jcajce.spec.SkeinParameterSpec

All Implemented Interfaces:

java.security.spec.AlgorithmParameterSpec

public class SkeinParameterSpec

extends java.lang.Object

implements java.security.spec.AlgorithmParameterSpec

Parameters for the Skein hash function - a series of byte[] strings identified by integer tags.

Parameterised Skein can be used for: MAC generation, by providing a key. Randomised hashing, by providing a nonce. A hash function for digital signatures, associating a public key with the message digest. A key derivation function, by providing a key identifier. Personalised hashing, by providing a recommended format or arbitrary personalisation string.
