PSgWrite is a tool for creating digital signatures, just like
<a href="../sigwrite/index.html">SigWrite</a>,
except that it uses a different format that is more
or less compatible with the program MacPGP.

<p>
The related tool
<a href="../psgcheck/index.html">PSgCheck</a>
can check digital signatures created with PSgWrite.
</p>
<p>
PSgWrite is in part descended from MacPGP source code, which, as far as
I can tell, allows derived works for noncommercial use. PSgWrite is
generally compatible with MacPGP, but it is easier to legally
distribute, since it doesn&rsquo;t do cryptography. Since it only does
one thing it should also be easier to use.
</p>
<p>
PSgWrite only handles a subset of secret keys that MacPGP does.
For one thing, it does not handle encrypted keys, which is what
MacPGP would normally generate.

<p>
Here is the md5 checksum for the download, signed with
