Method Detail

decode

protected void decode(byte[] privateKey)
               throws java.security.InvalidKeyException

Simply hold onto the Raw Private Key Data. This wrapped key is used to determine the algorithm that should be used for this Private Key.

Specified by:

decode in class PrivateKeyInfo

Parameters:

privateKey - the private key as DER encoded byte array

Throws:

java.security.InvalidKeyException - if the does not match to the implemented public-key algorithm

encode

protected byte[] encode()

Description copied from class: PrivateKeyInfo

Abstract method to be implemented for encoding this private key according to DER.

Specified by:

encode in class PrivateKeyInfo

Returns:

the private key as a DER encoded ASN.1 data structure

getAlgorithm

public java.lang.String getAlgorithm()

Return a String representation of the AlgorithmID which will tell us the algorithm to use

Specified by:

getAlgorithm in interface java.security.Key

Specified by:

getAlgorithm in class PrivateKeyInfo

Returns:

the name of the algorithm

getAlgorithmID

public AlgorithmID getAlgorithmID()

Returns:

the AlgorithmID for this WrappedPublicKey. This is useful to know what ObjectID has been used to encode the AlgorithmID.
