NAME
       key_decryptsession,   key_encryptsession,   key_setsecret,  key_gendes,
       key_secretkey_is_set - interfaces to rpc keyserver daemon

SYNOPSIS
       #include <rpc/rpc.h>

       int key_decryptsession(const char *remotename, des_block *deskey);

       int key_encryptsession(const char *remotename, des_block *deskey);

       int key_gendes(des_block *deskey);

       int key_setsecret(const char *key);

       int key_secretkey_is_set(void);


DESCRIPTION
       The functions here are used  within  the  RPC's  secure  authentication
       mechanism  (AUTH_DES). There should be no need for user programs to use
       this functions.

       The function key_decryptsession() uses the (remote) server netname  and
       takes  the DES key for decrypting. It uses the public key of the server
       and the secret key associated with the effective  UID  of  the  calling
       process.

       The  function  key_encryptsession()  is  the inverse of key_decryptses-
       sion().  It encrypts the DES keys with the public key of the server and
       the  secret  key associated  with the effective UID of the calling pro-
       cess.

       The function key_gendes() is used to ask the  keyserver  for  a  secure
       conversation key.

       The  function  key_setsecret() is used to set the key for the effective
       UID of the calling process.

       The function key_secretkey_is_set() can be used to determine whether  a
       key has been set for the effective UID of the calling process.


NOTE
       Please  note  that  we  talk about two types of encryption here. One is
       asymmetric using a public and secret key. The other is  symmetric,  the
       64-bit DES.
       The routines were part of the linux/doors-project, abandoned by now.


RETURN VALUES
       The functions return 1 on success and 0 on failure.
