Package org.bouncycastle.jcajce.spec

Class 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.
