* The keyserver is a public key storage/encryption/decryption service
* The encryption method used is based on the Diffie-Hellman exponential
* key exchange technology.
*
* The key server is local to each machine, akin to the portmapper.
* Under TI-RPC, communication with the keyserver is through the
* loopback transport.
*
* NOTE: This .x file generates the USER level headers for the keyserver.
* the KERNEL level headers are created by hand as they kernel has special
* requirements.
