User certificates can be automatically requested via our e-mail encryption gateway by sending an empty e-mail with the subject GetPublicKey to the respective e-mail address. The Bundesbank's e-mail gateway system sends back an automated and signed e-mail containing the e-mail address' public key. If the requested e-mail address does not have its own public key yet, the domain key (see below) is sent back.

You can also ask a member of staff directly to send you a signed e-mail.

In addition to the individual user certificates, the Bundesbank uses the following domain keys.
