KEY_SETSECRET(3) Linux Programmer's Manual KEY_SETSECRET(3)
key_decryptsession, key_encryptsession, key_setsecret, key_gendes,
key_secretkey_is_set - interfaces to rpc keyserver daemon
#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);
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.
These functions return 1 on success and 0 on failure.
For an explanation of the terms used in this section, see
attributes(7).

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.
