Everything works. Encryption just like I want it.

I have successfully implemented this plugin both for PGP and S/MIME encryption and it does the job just like it should. I can use the keys that I am already using for various email accounts and thus safely transmit any emails, including those from contact forms.
It is not understandable to me how so few people are implementing this plugin, since GDPR is necessitating protection of user data – and that certainly includes contact form entries. Anyways, keep up the good work & please keep updating the plugin if ever PHP development should require it 😉 I’ll see to it that you receive a good donation for your work within a few months. Cheers!
