Quite simply because it ensures that only the sender and recipient of an e-mail can read the message. A digital signature guarantees the authenticity of the sender and the content for you as the recipient.
Helaba provides you with several options for secure e-mail communication:
If your company supports PGP or S/MIME encryption, we need either a PGP key or an S/MIME certificate from you or your domain.
You can transmit this information to us in the following way:
If your company has a domain certificate and we do not already have it, please send it in an unencrypted zip file to scrmlhlbd.
If you would like to send encrypted e-mails to Helaba yourself, you either need the certificate or the key of the recipient at Helaba or, alternatively, our domain certificate.
The certificates or keys of specific Helaba e-mail addresses can be obtained on the Secure E-Mail Webinterface at https://secure-mail.helaba.de.
If your company does not support either of the two encryption methods mentioned above, you can communicate securely with Helaba using our Secure E-Mail Webinterface. In order to do this, you only need to be registered.
The registration process is initiated when your contact person at Helaba sends you a confidential e-mail. You will then receive an e-mail from "Kryptofirstname.lastname@example.org" containing further information about the registration process.
You can now log in on the Secure E-Mail Webinterface at https://secure-mail.helaba.de. Your contact person at Helaba will have received the initial password and can give it you over the phone.
On the Secure E-Mail Webinterface, you will be able to read or reply to e-mails or download them to your computer. You can also change your Secure E-Mail password or upload your certificate or key here.
