This is the wrong enum to use.

The determination of what a key can be used for with respect to signature
algorithms is, in part, determined by the client certificate and the keys
authorized usages.

You should just be talking about algorithms here (RSA, DSA, ECDSA).

Ok, I'll not touch SSLClientCertType then, and try to define another enum for
this.

+// Register JNI methods
+NET_EXPORT bool RegisterKeyStore(JNIEnv* env);
