<title>Attach a photo to your key</title>

|
|
|
<p>You can attach a photo ID to your PGP keys so that everyone can verify the
|
|
ownership of your keys after looking at your photo. Though a key with an
|
|
attached photo will provide a slightly better level of security than a key
|
|
with no photo, checking the photo on a key is not as safe as checking the
|
|
<link xref="misc-key-fingerprint">fingerprint of the key</link> because
|
|
anyone having your photos can create a key with your photo ID while the key
|
|
fingerprint cannot be mimicked.</p>
|
|
|
|
<note style="info">
|
|
<p>Unlike the restrictions in <app>GPG</app>, the photo ID you want to
|
|
upload need not be in the <file>JPEG</file> format. <app>Passwords and
|
|
Keys</app> lets you upload your photo in <file>png</file>,
|
|
<file>jpg</file> and several other common image formats.</p>

<steps>
|
|
<title>To attach a photo ID to a PGP key:</title>
|
|
<item>
|
|
<p>Select <gui>GnuPG keys</gui> from the left side panel.</p>
|
|
</item>
|
|
<item>
|
|
<p>Select the PGP key.</p>
|
|
</item>
|
|
<item>
|
|
<p>Right click on the chosen key and select
|
|
<guiseq><gui style="menuitem">Properties</gui>
|
|
<gui>Owner</gui></guiseq>.</p>
|
|
</item>
|
|
<item>
|
|
<p>Press the <gui style="button">+</gui> button on the left
|
|
hand side to add a photo.</p>
|
|
</item>
|
|
<item>
|
|
<p>Select the photo from your computer.</p>
|
|
</item>
|
|
<item>
|
|
<p>Click <gui style="button">Close</gui> to finish.</p>
|
|
</item>
|
|
</steps>
|
|
|
|
<note style="tip">
|
|
<p>The photos you select should be small in size, preferably about 120 by
|
|
150 pixels. Since a photo ID is always attached to its key, a large photo
|
|
will increase the key size and slow down all operations that use the key.
|
|
<app>Passwords and Keys</app> resizes large photos to the optimal size
|
|
after asking for your confirmation.</p>
