Class RC2Parameters

java.lang.Object
  extended by java.security.AlgorithmParametersSpi
      extended by com.ibm.crypto.provider.RC2Parameters

public final class RC2Parameters
extends AlgorithmParametersSpi

This class implements the parameters used with the RC2 algorithm in various mode (CBC, ECB, OFB, CFB, PCBC). Parameters are defined in the standards (RFC 2268) as follows:

 RC2-CBCParameter ::= CHOICE {
  iv IV,
  params SEQUENCE {
      version RC2Version,
      iv IV
  }
 }
 

RC2 is a 64-bit block cipher with a variable-length key.
