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 effective 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.
