KEY_SETSECRET(3)		    Linux Programmer's Manual			 KEY_SETSECRET(3)

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_decryptsession().  It encrypts the
       DES keys with the public key of the server and the secret key associated with  the  effec-
       tive UID of the calling process.

       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.

RETURN VALUE
       These functions return 1 on success and 0 on failure.

NOTES
       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.

       These routines were part of the Linux/Doors-project, abandoned by now.
