JCE provider implementation

I need to write a java JCE provider. I have been looking in the net for seve开发者_JAVA技巧ral days and I could not find solution. Could you please give me some useful informaion. Regards,

Documentation is here and here, but why would you want to do this? Most of the mainstream cryptographic algorithms are implemented already either by Sun or BouncyCastle.

Just to add to ig's answer, note that the Sun/Oracle JDK requires the JCE provider to be signed by Sun, Oracle or IBM CA. This isn't something you can achieve easily (if at all).

So if it's just for educational purposes, you can follow the documentation for development and use OpenJDK for testing, because it does not require the JCE provider to be signed. There's also a Windows OpenJDK version available.
