engineGetEncodedback to summary
protected byte[] engineGetEncoded() throws IOException

Implements abstract java.security.AlgorithmParametersSpi.engineGetEncoded.

Doc from java.security.AlgorithmParametersSpi.engineGetEncoded.

Returns the parameters in their primary encoding format. The primary encoding format for parameters is ASN.1, if an ASN.1 specification for this type of parameters exists.

Returns:byte[]

the parameters encoded using their primary encoding format.

Exceptions
IOException:
on encoding errors.
