* 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.
