SYNOPSIS

17
18       int key_gendes(des_block *deskey);

DESCRIPTION

24       The functions here are used  within  the  RPC's  secure  authentication
25       mechanism (AUTH_DES).  There should be no need for user programs to use
26       this functions.
27
28       The function key_decryptsession() uses the (remote) server netname  and
29       takes the DES key for decrypting.  It uses the public key of the server
30       and the secret key associated with the effective  UID  of  the  calling
31       process.
32
33       The  function  key_encryptsession()  is  the inverse of key_decryptses‐
34       sion().  It encrypts the DES keys with the public key of the server and
35       the  secret  key  associated  with  the  effective  UID  of the calling
36       process.
37
38       The function key_gendes() is used to ask the  keyserver  for  a  secure
39       conversation key.
40
41       The  function  key_setsecret() is used to set the key for the effective
42       UID of the calling process.
43
44       The function key_secretkey_is_set() can be used to determine whether  a
45       key has been set for the effective UID of the calling process.
46

RETURN VALUE

48       These functions return 1 on success and 0 on failure.

NOTES

63       Note that we talk about two types of encryption here.  One is  asymmet‐
64       ric  using a public and secret key.  The other is symmetric, the 64-bit
65       DES.
66
67       These routines were part of the Linux/Doors-project, abandoned by now.
