GnuPG Secure Form

These scripts were created to allow someone without GNUPG to send a message or documents securely to someone that does use GNUPG.

SETUP:

• Be sure you use an HTTPS connection. Let's Encrypt provides free SSL certificates.
• Edit the config.php file based on your environment.
• Add your GNUPG public key and the trustdb.gpg file to a directory that the web user can access.
• Be sure you can send email from your web server host.
• For the key you will use, run the command:

gpg --list-keys

and use the long public key fingerprint in the config file (config.php) for "KEY_ID." It will need to the ID used to encrypt and decrypt the messages.

Requirements:

• PHP 7.X
• PHP GnuPG module (apt install php-gnupg on Ubuntu)
• You may want to add a Captcha if this is not behind an existing authentication system.
