key_encryptsession(3) -- Linux man page
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.
NOTE
Please 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.
The routines were part of the linux/doors-project, abandoned by now.
RETURN VALUES
The functions return 1 on success and 0 on failure.
