DrbgParameters
public static final class DrbgParameters.Instantiation
extends Object
implements SecureRandomParameters
DRBG parameters for instantiation.
When used in
SecureRandom.getInstance(String, SecureRandomParameters)
or one of the other similar getInstance
calls that take a
SecureRandomParameters
parameter, it means the
requested instantiate parameters the newly created SecureRandom
object must minimally support. When used as the return value of the

- If used in
getInstance
, returns the requested personalization string as a newly allocated array, ornull
if no personalization string is requested. The same string should be returned ingetParameters
as a new copy, ornull
