|
|
Many commands and options require a <firstterm>key specifier</firstterm>.
|
|
A key specifier is the key ID or any portion of ther user ID of
|
|
a key.
|
|
Consider the following example.
|
|
|
|
<screen width="80">
|
|
<prompt>alice%</prompt> <userinput>gpg --list-keys chloe</userinput>
|
|
pub 1024D/B87DBA93 1999-06-28 Chloe (Jester) <chloe@cyb.org>
|
|
uid Chloe (Plebian) <chloe@tel.net>
|
|
sub 2048g/B7934539 1999-06-28
|
|
</screen>
|
|
|
|
For this key, <literal>0xB87DBA93</literal>,
|
|
<literal>Chloe</literal>,
|
|
<literal>Plebian</literal>, and
|
|
<literal>oe@tel</literal>
