To use gpg, your home directory should contain a <code>.gnupg</code> directory owned by you with permissions 700. To create this for the first time:
<pre>
gpg --gen-key
</pre>

To encrypt a file:
<pre>
gpg -r <usr> -e <orig-file>
</pre>

To decrypt a file:
<pre>
gpg -r <usr> -o <orig-file> -d <gpg-file>
</pre>

To create an encrypted tar file:
<pre>
tar cf test.tar <dir>
gpg -r root -e test.tar
rm -f test.tar
</pre>

To extract an encrypted tar file:
<pre>
gpg -r root -d test.tar.gpg | tar xf -
</pre>

If the <code>.gnupg</code> directory isn't in the right place, you may need to throw in the following option:
<pre>
gpg --homedir /tmp/.gnupg ...
</pre>
