Whoever receives an e-mail nowadays cannot rely on the fact that it actually originates from the specified sender. Nor can the recipient be certain that a message which has been received is unchanged and complete. E-mail sender data are increasingly being falsified by worms and spams.
This is why we at Bischof+Klein have decided to provide each e-mail which leaves the company with a digital signature, therefore making information exchange secure and trustworthy. The message is "electronically sealed" by this signature. As the recipient, you can now reliably determine whether
- the message has been changed on its way to you (integrity of the transmitted data)
- the message actually originates from Bischof+Klein (authenticity of the data source)
To check the validity of mails signed by us, you have to install the following certificates, which can be downloaded from Deutsche Telekom's T-Telesec Trustcenter:
In addition, we offer confidential communication with encryption using S/MIME and PGP. The digital signature below our e-mails simultaneously provides you with our public key. This enables you to send us an encrypted message.
If you also have a public key yourself, please make this available to us. We are then able to send to send you encrypted e-mails. If you already use certificates and these are accessible via a public LDAP server, we would be grateful if you would send us this information via our contact form, stating the key word "LDAP server information".
