Constructor Detail

PWRIKekWrapParameterSpec

public PWRIKekWrapParameterSpec(AlgorithmID encryptionAlgorithm)

Creates a PWRIKekParametersSpec from the given encryptionAlgorithm value.

Parameters:

encryptionAlgorithm - the encryption algorithm

PWRIKekWrapParameterSpec

public PWRIKekWrapParameterSpec(ASN1Object obj)
                         throws CodingException

Creates a new PWRIKekWrapParameter from an ASN1Object. The ASN1Object must be a PWRIKekWrapParameter structure.

Parameters:

obj - the ASN.1 representation of a PWRIKekWrapParameter structure

Throws:

CodingException - thrown if an errors occurs while decoding the ANS1Object

Method Detail

getEncryptionAlgorithm

public AlgorithmID getEncryptionAlgorithm()

Return the encryption algorithm.

Returns:

the encryption algorithm

decode

public void decode(ASN1Object obj)
            throws CodingException

Decodes a PWRIKekWrapParameterSpec from an ASN1Object. The ASN1Object must be a PWRIKekWrapParameter structure.

Parameters:

obj - an ASN.1 representation of a PWRIKekWrapParameter structure

Throws:

CodingException - thrown if an errors occurs while decoding the ANS1Object
