During PCI audit we have such request from auditors:
xxx.xxx.xxx.xxx 51111 Unique Test Issue: Weak hash algorithms active Measure: Use strong hash algorithms
xxx.xxx.xxx.xxx 51111 Unique Test Issue: Weak encryption ciphers active Measure: Deactivate weak ciphers
On this ports works PCM agent. According technical literature this alert is caused by self-signed certificate produced from PCM.
Do you have an information - is it possible to use external CA signed certificate for PCM agent?
Or can I request statement from HP that it is not possible to change and it is not an issue.
Thank you in advance!
P.S. This thread has been moved from ProCurve / ProVision-Based to PCM. -HP Forum Moderator

It doesn't appear to support external certificates. If you update to the latest version and regenerate the certificate , it might generate a longer key/better algorithm by default. However I am only guesssing.
What I would do is:
1. If you have paid support, open a proper ticket. If you have the paid for PCM+, that is.
2. Consider a plan to migrate off PCM, as it's heading for EOL. I imagine the auditors will be less than happy if they find an issue with it and it's unsupported software.

Did it have any details about what was wrong? Typically if there is an issue with self-signed vs CA, it would say that.
Not "weak hash algorithms" or "weak encryption ciphers". A certificate does have a encryption key length but again, it ideally should mention that.
This means these are controlled by the software, not the certificate.
If you would like an analysis of your certificate, you can attach it on a reply.

I would assume it's an issue, unless your management network is behind a firewall.
