A quick&dirty port of OpenPGP.js to Google Apps Script

The file OpenPGP-v5.3.0.js is the unmodified OpenPGP.js 5.3.0 single-file JS library.

The file OpenPGP-v5.3.0.gs is a modified version of OpenPGP-v5.3.0.js with some ad-hoc changes to make it work with Google Apps Script.

The file Code.gs is a simple example app that uses OpenPGP.gs to sign a message.

The openpgpgs-v5.3.0 branch contains the changes relative to the OpenPGP.js v5.3.0 release tag.
