Commerce GPG provides a credit card payment method for Drupal Commerce that encrypts credit card information using the PHP: GnuPG extension. A common use case would be for shops that would prefer to use an existing terminal for manual card processing or have an accounting system that handles processing. The GPG encrypted block is available in a commerce-order token for embedding in emails generated by the order action. The block is typically decrypted by an email client plugin.
This module was not created to be a method of secure credit card storage for later online use. It purposely provides no method of decryption and is strictly designed for secure transmission of the credit card data only.
