Class AesKeyWrapParameters

java.lang.Object

java.security.AlgorithmParametersSpi

com.entrust.toolkit.security.crypto.params.AesKeyWrapParameters

public final class AesKeyWrapParameters
extends java.security.AlgorithmParametersSpi

An opaque algorithm parameters representation for Entrust's AesKeyWrap or AesKeyWrapPad algorithm implementation.

For a detailed description of how the initial value is used by the AES key wrap algorithm, refer to the documentation on the corresponding transparent algorithm parameters representation AesKeyWrapParameterSpec. To convert this opaque representation into a transparent representation call getParameterSpec(AesKeyWrapParameterSpec.class). Finally, for parsing and encoding of this parameter, only the 'RAW' encoding is supported; by default the 'RAW' encoding is used.

Constructor Detail

AesKeyWrapParameters

public AesKeyWrapParameters()

The constructor; creates a new instance of AES key wrap algorithm parameters.

This should never be invoked manually. It only exists so that the Java Cryptography Architecture can create new instances of AES key wrap algorithm parameters.
