    You can send and receive encrypted emails with shop@nitrokey.com, support@nitrokey.com and reply@nitrokey.com, 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 encrypt-my-emails@nitrokey.com. The email address you use must be included in the PGP key or S/MIME certificate. S/MIME certificates are only accepted from common CAs but not from own CAs.
