Signed JCE and providers jars

The OpenJDK JCA does not do provider signature checking. So you can install your own providers and don’t need to sign them.

Betreff: Signed JCE and providers jars

I’ve downloaded OpenJDK builds from AdoptOpenJDK and Azul Zulu, and I’ve noticed that the jce.jar, sunjce_provider.jar and sunpkcs11.jar jar files do not appear to be signed. I’m surprised they work without being signed, but I also haven’t been able to find anyone asking how to get signed versions of the Sun JCE.

How can I get signed versions of the Sun JCE jars, or should I not worry about it, and if so, why not?

Thanks,
David
