HI .. nice work .. do you plan to support Argon2 ??

Hey!
That would be nice, but it's not supported out of the box in JDK provider, but probably will be: https://bugs.openjdk.org/browse/JDK-8253914

Still, it's supported in BouncyCastle, so may be it's possible to somehow support it there. But because there are no parameters classes in JDK, probably the only way will be to create a separate provider for BC, so that it will be possible to access their API's directly.

So, the answer is yes, but probably not in near future
