SSL Certificate Signed Using Weak Hashing Algorithm

Modified on 2025-06-10 20:14:11 +0200

Hi Team,

Would like to enquire on regards to some VA detected by Nessus as subjected.

Subject: O=PRTG Demo Certificate/CN=PRTG Demo Certificate Signature Algorithm: SHA-1 With RSA Encryption

Currently what is recommended and what we are using is SHA256.

Question: Is it safe to remove the Demo Certification? Does this have any impact on the communications on the server health detection?

If needed to generate a new CA, any steps or methods safe for us to follow for enterprise environment?

Thank you in advanced! A'an

Hi there,

You can of course exchange the certificate with one of your certificates using a stronger hash algorithm. In regards to the guide, you can follow this guide to import the certificate: https://www.paessler.com/manuals/prtg/using_your_own_ssl_certificate
