A combination of an S/MIME-Certificate and an SSL/TLS-Certificate doesn’t exist for the reason that they serve drastically different purposes. An S/MIME-Certificate secures the encrypted conversation via e-mail. Therefore it prevents an involuntary flow of information to third parties and secures the electronic correspondence with customers and business partners. An SSL/TLS-Certificate encrypts the transport path between […]
Yes, this is certainly possible. We only need one order for each person via our website.
Basically, you have two options: You order each e-mail certificate individually on our website. You have the possibility to apply for an EPKI account => Please contact us for advice on EPKI. Use our call-back service.

The advantage of S/MIME (Secure/Multipurpose Internet Mail Extensions) in comparison with PGP is mainly that S/MIME-Certificates are usually handed out by well-known Certification Authorities (CAs) which also sell SSL/TLS-Certificates. This encourages reliance severely. In contrast, PGP (Pretty Good Privacy) relies on private keys. Those are generated while the e-mail-address is installed and therefore have to […]
The validation call is only made by GlobalSign and Comodo. These two CAs contact the certificate holder by telephone. It should be noted that only the telephone number that is visible in a public register (e.g. the local one) is called. For further questions please contact our support team at +49 661 480 276 10.
All CAs (certification authorities) deliver the S/MIME certificate in .pfx or .p12. One exception is Certum, where the S/MIME certificate is delivered in .cer and .pem. For further questions please contact our support team at +49 661 480 276 10.
No, an SSL/TLS certificate does not have an unlimited validity period. The CAB Forum (CA/Browser Forum) has decided that since the beginning of 2015 SSL/TLS certificates may only be issued with a maximum term of 3 years for domain and organization validated certificates and a maximum term of 2 years for extended validation certificates. If […]
Yes, you can create an SSL/TLS certificate yourself. These are then the so-called self-signed certificates. These self-signed certificates can be issued independently. The disadvantage is that the certificates are marked as „not trustworthy“ in the browser, because your own root certificates are not stored in the browser. Thus, a self-created SSL/TLS certificate is in fact […]
Yes, our SSL/TLS certificates are supported by all common browsers. In the respective product description you can check whether your desired SSL/TLS certificate is also supported by your favourite browser. Furthermore, you should also pay attention to the correct algorithm (e.g. ECC and DSA are not supported by all operating systems/browsers). It is important that […]
