Синопсис (Synopsis)
#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);
Описание (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.
Возвращаемое значение (Return value)
These functions return 1 on success and 0 on failure.

Примечание (Note)
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.
