Hello,

I'm trying to use our own SSL certifivate but I had no luck yet. Our certificate came along with the following files:

  • AddTrustExternalCARoot.crt
  • COMODOHigh-AssuranceSecureServerCA.crt
  • prtg_tmts_nl.crt

I looked here https://kb.paessler.com/knowledgebase/en/topic/283-how-can-i-use-a-trusted-ssl-certificate-with-the-prtg-web-interface

But I don't know how to decrypt the .key file. I tried copying the files I had, after renaming them first, but when I tried to relaunch prtg, it simply won't run.

Any suggestions on how to proceed?

Your Sincerely,

Michel Butzelaar

Dear Michel,

So, one of your files must be the root certificate, one the server certificate and one the private key file.

>But I don't know how to decrypt the .key file.

The issuer of your certificate has sent you the encrypted private key file along with a password. Please use the private key file in combination with the password to generate another private key file which is not encrypted:

  • Download openssl.
  • On command line, run: openssl rsa -in [encrypted-key].key -out prtg.key
  • At the "Enter PEM pass phrase:" prompt enter the password for the key

Please make sure your certificates and key files are PEM encoded. Use SSL converter tools, if necessary.
