KEY_SETSECRET(3)					     Library Functions 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_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.
