A simple PGP Mail Form Plugin. Enter your PGP public key, then visitors will be able to send you PGP encrypted messages by mail from a form.
The plugin for me only works with the public key generated on https://wp2pgpmail.com/pgp-key-generator/ and not with the PGP key I use day to day, that was generated by Enigmail.
If I were to suggest one thing that could be improved in 1.18, it would be adding CSS classes to the generated HTML form, so it would be easier to style it without nasty CSS tricks and make it look better on every WordPress theme.
Awesome little plug-in. Works as advertised. Thank you for giving us a free version. You may recall, Phil Zimmermann used to give away PGP for free as well. The only constructive criticism I can offer up is I don't think you need the captcha option if the message wont be sent unless you click the "encrypt" button. Not sure how a bot could do that....but I might be wrong. Other than that, I love it. Thanks.
This is an excellent and very easy to set up and use plugin. I've used several other contact forms in the past and this is as easy as the best of them and encrypts the message sent as well. It also includes an anti spam field to stop the spammbots. Just follow the video instructions to set up.
What it does:
wp2pgpmail is a simple, anti-spam, contact form with an extra 'encrypt' button. A site visitor types a message in the usual way. Before sending they press 'encrypt' and the message is encrypted using your public pgp key (these can be generated using the Chrome plugin 'Mailvelope' if you don't have PGP or GnuPG). The encryption takes place on the clients device not the server. That is before any part of the message is uploaded on to the internet.
Since so many people are slack about encryption this seems about the simplest way possible to get encrypted messages sent to you. Visitors to your site don't need any extra software or do anything more than press the 'encrypt' button.
