Method Detail

engineGetEncoded

protected byte[] engineGetEncoded()
                           throws IOException

Returns the GCM parameters encoded in a proprietary format. We don't support ASN.1 at this time.

Specified by:

engineGetEncoded in class AlgorithmParametersSpi

Returns:

Encoded representation of the GCM parameters

Throws:

IOException

engineGetEncoded

protected byte[] engineGetEncoded(String format)
                           throws IOException

Returns the GCM parameters encoded in a proprietary format. We don't support ASN.1 at this time.

Specified by:

engineGetEncoded in class AlgorithmParametersSpi

Parameters:

format - Only "Luna" is supported

Returns:

Encoded representation of the GCM parameters

Throws:

IOException
