The functions here are used within the RPC’s secure authentication
mechanism (AUTH_DES). There should be no need for user programs to use
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
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
The function key_gendes() is used to ask the keyserver for a secure
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.
These functions return 1 on success and 0 on failure.
Note that we talk about two types of encryption here. One is
asymmetric using a public and secret key. The other is symmetric, the
These routines were part of the Linux/Doors-project, abandoned by now.
