Do I need to install all the certificates that I received?

After issuing the certificate, you will receive an e-mail with 2 files from us: A .crt file for the actual certificate and a .ca file with the appropriate certificate chain. All contained certificates must be uploaded to the webserver so that the certificate is classified as trustworthy by all supporting browsers. To make sure that your certificate has been installed correctly, you can use the SSL-Checker on our website

In case your web server does not support the transmitted file format, we also offer a converter on our website to convert the certificate into another file format.

Installation example Apache & mod_ssl / OpenSSL

  • Unpack the files and yourSERVERNAME.crt contained in the zip file into the folder /etc/ssl/crt/ and then your PrivateKey yourSERVERNAME.key to /etc/ssl/key/.
  • Then set the files to readonly for the system user
  • chmod 400 filename.
  • Now change the httpd.conf for the corresponding vhost as follows:

SSLCertificateFile /etc/ssl/crt/yourDOMAINNAME.crt

SSLCertificateKeyFile /etc/ssl/key/yourDOMAINNAME.key

SSLCertificateChainFile /etc/ssl/crt/

Please note that the path specifications may differ from your system.
