After the download, the certificate should be renamed and saved accordingly. Depending on the web browser settings, the certificate file is usually located in the “Downloads” folder.

• Rename the certificate file according to the above notation
• Save the certificate file and the two files created above (Key & CSR) in a suitable location outside your PC, e.g.
  • in the Collaboration Cloud in the “Personal/Certificates” folder
