Authenticated Transfer</a></h1>
<p>RFC1179 does not provide any authentication or encryption
mechanism for the transfer of jobs or commands to the <b class=
"APPLICATION">lpd</b> print server. The Authenticated Transfer
operation was added to allow an encrypted or authenticated
transfer of print jobs or commands.</p>
<p>Since there are various restrictions on the incorporation of
authentication facilities into programs, <b class=
"APPLICATION">LPRng</b> supports authentication by providing a
simple interface to encryption programs.</p>
<p>The idea is that when authentication is required when
sending a job, <b class="APPLICATION">LPRng</b> will generate a
block transfer job as described for the <a href=
"sendblockformat.htm">Block Job Transfer</a> operation, and
then invoke a set of programs to encryt and transfer the file,
and encrypt and transfer the returned status.</p>
<p>Similarly, when sending a command, the command information
will be placed in a file and the encrypted file will be
transferred.</p>
<p>This technique means that the programs and support to do
encryption are external to <b class="APPLICATION">LPRng</b>,
and can use any type of method that they choose to implement
the secure and/or authenticated transfer.</p>
<p>See <a href="authref.htm">Authentication and Encryption</a>
for details on the authentication interface.</p>
