WP PGP Encrypted Emails can automatically sign and encrypt any email that WordPress sends to your site’s admin email address or your users’s email addresses. You give it a copy of the recipient’s OpenPGP public key and/or their S/MIME certificate, and it does the rest. You can even automatically generate an OpenPGP signing keypair for your site to use. Encrypting outgoing emails protects your user’s privacy by ensuring that emails intended for them can be read only by them, and them alone. Moreover, signing those emails helps your users verify that email they receive purporting to be from your site was actually sent by your server, and not some imposter. If you’re a plugin or theme developer, you can encrypt and/or sign arbitrary data using this plugin’s OpenPGP and S/MIME APIs, which are both built with familiar, standard WordPress filter hooks. This enables you to develop highly secure communication and publishing tools fully integrated with your WordPress install. See the README.markdown file for details on cryptographic implementation and API usage. Donations for this and my other free software plugins make up a chunk of my income. If you continue to enjoy this plugin, please consider making a donation.
