public class RC2ParameterSpec

extends java.lang.Object

implements AlgorithmParameterSpec

RC2 parameter specification.

Attention: This is not a SUN implementation!

This class has been developed by IAIK according to the documentation publically available.
For SUNīs documentation of this class see http://java.sun.com/security/JCE1.2/spec/apidoc/index.html

This class represents an initialization vector (IV), used as parameter by the RC2 algorithm.

Constructor Summary

RC2ParameterSpec(int effectiveKeyBits)

RC2ParameterSpec(int effectiveKeyBits, byte[] initVector)
Creates a RC2 Parameter specification by using the first 8 bytes of the supplied byte array as initialization vector (IV).

RC2ParameterSpec(int effectiveKeyBits, byte[] initVector, int offset)
Creates a RC2 Parameter specification by using 8 bytes of the supplied byte array as IV, beginning at the given offset.

Method Summary

int	getEffectiveKeyBits() Return the number of effective key bits.
byte[]	getIV() Returns a copy of the initialization vector (IV) as byte array representation.
