<title>Exporting Public Keys</title>
|
|
<body>
|
|
<p>There are two methods of exporting public keys, both of which are very similar to the
|
|
other. The default method, <codeph>key_export()</codeph> will export a public key or keys
|
|
matching a specified pattern as normal. The alternative, the
|
|
<codeph>key_export_minimal()</codeph> method will do the same thing except producing a
|
|
minimised output with extra signatures and third party signatures or certifications
|
|
removed.</p>

<p>It is important to note that the <codeph>result</codeph> will only return
|
|
<codeph>None</codeph> when a pattern has been entered for <varname>logrus</varname>, but
|
|
it has not matched any keys. When the search pattern itself is set to <codeph>None</codeph>
|
|
this triggers the exporting of the entire public keybox.</p>
