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.
