Also RSASSA-PSS works better now with these changes.  I've also taken this opportunity to do some cleanup on CertificateBuilder and added a method which uses a default signing algorithm based on the key, so the `build()` method no longer needs to provide that algorithm (though one can if they wish for things like RSA signatures if they want a different message digest in the signature).
