E-mail Encryption

You can send and receive encrypted email with [email protected], [email protected] and [email protected], as well as receive encrypted order confirmations, invoices and delivery confirmations after placing an order. To do this, follow these steps:

  1. Send your PGP public key or S/MIME certificate as an attachment to [email protected]. The email address you use must be included in the PGP key or S/MIME certificate. The sender address of the email will be ignored. Attached PGP keys must be set as Content-Type "application/pgp-keys". You can do this by attaching and sending your PGP public key directly from your email program instead of going through a saved file.
  2. You will receive two email confirmations. If you do not receive any confirmation email or only one, either no PGP key and no S/MIME certificate could be extracted or they are issued for different email addresses than the email address you are using. In this case, check the instructions in point 1.
  3. Download the respective PGP key or S/MIME certificate and use it for email encryption:
