.SH DESCRIPTION
|
|
|
|
|
The functions here are used within the RPC's secure authentication
|
2007-04-12 22:42:49 +00:00
|
|
|
mechanism (AUTH_DES).
|
|
|
|
|
There should be no need for user programs to
|
2004-11-03 13:51:07 +00:00
|
|
|
use this functions.
|
|
|
|
|
|
|
|
|
|
The function
|
2007-04-12 22:42:49 +00:00
|
|
|
.BR key_decryptsession ()
|
|
|
|
|
uses the (remote) server netname and takes the DES key
|
|
|
|
|
for decrypting.
|
|
|
|
|
It uses the public key of the server and the
|
2004-11-03 13:51:07 +00:00
|
|
|
secret key associated with the effective UID of the calling process.
|
|
|
|
|
|
|
|
|
|
The function
|
|
|
|
|
.BR key_encryptsession ()
|
|
|
|
|
is the inverse of
|
|
|
|
|
.BR key_decryptsession ().
|
|
|
|
|
It encrypts the DES keys with the public key of the server and
|
2008-07-01 14:15:13 +00:00
|
|
|
the secret key associated with the effective UID of the calling process.
|
2004-11-03 13:51:07 +00:00
|
|
|
|
|
|
|
|
The function
|
2007-04-12 22:42:49 +00:00
|
|
|
.BR key_gendes ()
|
2004-11-03 13:51:07 +00:00
|
|
|
is used to ask the keyserver for a secure conversation key.
|
|
|
|
|
|
|
|
|
|
The function
|
2007-04-12 22:42:49 +00:00
|
|
|
.BR key_setsecret ()
|
|
|
|
|
is used to set the key for the effective UID of the calling process.
|
2004-11-03 13:51:07 +00:00
|
|
|
|
|
|
|
|
The function
|
|
|
|
|
.BR key_secretkey_is_set ()
|
|
|
|
|
can be used to determine whether a key has been
|
2007-04-12 22:42:49 +00:00
|
|
|
set for the effective UID of the calling process.
|
2007-05-19 04:30:20 +00:00

|
|
.SH "RETURN VALUE"
|
|
|
|
|
These functions return 1 on success and 0 on failure.

|
.SH NOTES
|
2007-04-12 22:42:49 +00:00
|
|
|
Note that we talk about two types of encryption here.
|
2007-05-16 02:54:18 +00:00
|
|
|
One is asymmetric using a public and secret key.
|
2007-04-12 22:42:49 +00:00
|
|
|
The other is symmetric, the
|
2004-11-03 13:51:07 +00:00
|
|
|
64-bit DES.
