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(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_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.
