Class SkeinParameterSpec

java.lang.Object
org.bouncycastle.jcajce.spec.SkeinParameterSpec
All Implemented Interfaces:
AlgorithmParameterSpec
public class SkeinParameterSpec extends Object implements 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.
