java.lang.Objectorg.bouncycastle.jce.provider.BrokenKDF2BytesGenerator
public class BrokenKDF2BytesGenerator
Generator for PBE derived keys and ivs as defined by IEEE P1363a
This implementation is based on draft 9 of IEEE P1363a. Note:
as this is still a draft the output of this generator may change, don't
use it for anything that might be subject to long term storage.
