Specified by:

engineGetEncoded in class java.security.AlgorithmParametersSpi

Returns:

Encoded representation of the GCM parameters

Throws:

java.io.IOException

engineGetEncoded

protected byte[] engineGetEncoded(java.lang.String format)
                           throws java.io.IOException

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

Specified by:

engineGetEncoded in class java.security.AlgorithmParametersSpi

Parameters:

format - Only "Luna" is supported

Returns:

Encoded representation of the GCM parameters

Throws:

java.io.IOException
