KEY_SETSECRET(3)	   Linux Programmers Manual	     KEY_SETSECRET(3)



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

SYNOPSIS
       #include 

       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  RPCs  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.

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.
