*deskey);

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.
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.
The functions return 1 on success and 0 on failure.
