Are there any other open source JCE libraries besides BouncyCastle?

Question

I am looking for open source JCE libraries that implement some of the more esoteric encryption algorithms so that I can study their implementation. I would be especially interested in ones that implement Identity Based Encryption (IBE) as published by Stanford.

Answer 1

Cryptix (not sure what state its in at the moment but it was high quality when I used it last):

Answer 2

GNU Classpath also has their own JCE implementation, however, whether they support IBE is another story.
