Quick reference for <code>gpg</code> (GNU Privacy Guard), used for encryption, signing, and key management following the OpenPGP standard.
</p>
<h2>Key management</h2>
<ul>
<li><code>gpg --full-generate-key</code> – interactive key generation.</li>
<li><code>gpg --list-keys</code> / <code>gpg --list-secret-keys</code> – list public/secret keys.</li>
<li><code>gpg --delete-key &lt;ID&gt;</code> – delete a public key.</li>
<li><code>gpg --delete-secret-key &lt;ID&gt;</code> – delete a secret key.</li>
</ul>
<h2>Export / import keys</h2>
<ul>
<li><code>gpg --export -a &lt;ID&gt; &gt; public.asc</code> – export public key (ASCII armored).</li>
<li><code>gpg --export-secret-keys -a &lt;ID&gt; &gt; secret.asc</code> – export secret key (backup only).</li>
<li><code>gpg --import public.asc</code> – import a key.</li>
<li><code>gpg --recv-key &lt;ID&gt;</code> – fetch from keyserver (if configured).</li>
</ul>
<h2>Encrypt / decrypt</h2>
<ul>
<li><code>gpg -e -r &lt;recipient&gt; file</code> – encrypt to recipient’s key.</li>
<li><code>gpg -d file.gpg</code> – decrypt a file.</li>
<li><code>echo "secret" | gpg -e -r &lt;recipient&gt; &gt; secret.txt.gpg</code> – encrypt from stdin.</li>
</ul>
<h2>Signing</h2>
<ul>
<li><code>gpg -s file</code> – create a binary signature.</li>
<li><code>gpg -sa file</code> – create an ASCII-armored signature.</li>
<li><code>gpg --clear-sign file</code> – cleartext sign (visible content + signature block).</li>
<li><code>gpg --verify file.sig file</code> – verify a detached signature.</li>
</ul>
<h2>Trust and IDs</h2>
<ul>
<li><code>gpg --edit-key &lt;ID&gt;</code> – manage key, set trust, add UIDs, etc.</li>
<li><code>gpg --fingerprint &lt;ID&gt;</code> – show key fingerprint.</li>
<li>Verify fingerprints out-of-band (in person, chat, etc.) before trusting.</li>
</ul>
<h2>Tips</h2>
<ul>
<li>Use a modern key type (ed25519 or cv25519) where available.</li>
<li>Back up your secret key and revoke certificate somewhere safe.</li>
<li>Combine <code>gpg</code> with <code>pass</code> and <code>git</code> for a simple password manager.</li>
</ul>
