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(char *remotename, des_block *deskey);
     int key_encryptsession(char *remotename, des_block *deskey);
     int key_gendes(des_block *deskey);
     int key_setsecret(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
     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 asymmet-
     ric 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.
