Method Detail

getKANonce

byte[] getKANonce()

Returns a nonce that assures different key materials are generated. Each invocation of this method returns a new clone.

Returns:

a nonce, or null if not specified

getParameterSpec

java.security.spec.AlgorithmParameterSpec getParameterSpec()

Returns the algorithm-specific input parameters of this AgreementMethod. The returned parameters can be typecast to a AgreementMethodParameterSpec object.

Specified by:

getParameterSpec in interface AlgorithmMethod

Returns:

the algorithm-specific input parameters of this AgreementMethod (may be null if not specified)

getOriginatorKeyInfo

KeyInfo getOriginatorKeyInfo()

Returns key information from the originator used to determine the secret key. The marshalling method should ensure that the OriginatorKeyInfo belongs to the xenc namespace.

Returns:

an originator's KeyInfo or null if not specified

getRecipientKeyInfo

KeyInfo getRecipientKeyInfo()

Returns key information from the recipient used to determine the secret key. The marshalling method should ensure that the RecipientKeyInfo belongs to the xenc namespace.

Returns:

a recipient's KeyInfo or null if not specified
