I have the Certificate Patrol addon (website) installed in Firefox. While I mostly ignore the (far too many) warnings, today I saw that the certificate authority for my personal website has changed. This certificate is created by myself, self signed, and I didn't change anything for the past month or two.
I made a screenshot of the warning, and see two different SHA1 fingerprints. MD5 fingerprint changed from
undefined. Organization name (O) changed as well from
unknown to the name I gave it. I didn't click the "view certificate" buttons for both websites, and regret that now.
- What does this mean? Can I trust the certificate?
- How can I check that my certificate is still valid, created by me, not changed by someone or something else?
- Should I recreate it?
