      Hello,
      Opera 20.0 suddenly displays "Invalid certificate" messages that keep me from accessing to websites I'm sure they are reliable. With Firefox I can seamlessly access to them. What can I do? (apart from changing Opera for Firefox!)

          twitter.com works fine.

          twitter.com SSL EAV vertificate is from 08.04.2014 01:00:00 GMT

          PS: Your certificates in Windows are not up to date!

            And if so, why in Firefox it all runs fine?

              Because Firefox has its own certificate store; it does not use the Windows certificate store! Firefox updates its own certificates if necessary.

                OK. Then how on earth can I update a Windows certificate? I haven't the slightest idea about how to do it...

                  Your WIndows should so this automatically. And you can start Windows Update manually.

                    I think I've encountered that problem before. Log off and log on to the site (Twitter).

                      I noticed that I can't log into Dropbox anymore with Opium.

                      Is real Opera updating certificates automatically as well, because it worked, or does it have to do with relaxed settings I might have in Opera? Situations of this kind could be bypassed in the past, when the root authority is unknown (self issued certificate). Why is it different now?

                        I'm sure everyone has seen those certificates on Windows Update, If not set Windows Update to show all updates.

                          Opera 12 had its own root certificate store, a warning could be bypassed termporary or permanent, you were able to use the unknown certificate.

                          As Opera 20 uses the Windows certificate store, the warning can be bypassed.
                          If you want to use a unknown selfsigned certificate, you have to add it to Windows Trusted Root Certificates (But be careful using certificates without proofing they are really for the server!).

                            [b]I solved the problem updating my Windows XP to SP3.[/b] SP2 doesn't support SHA-256 certificates which are used by sites like twitter etc.

                              I've ran a rootsupd.exe (KB931125) sometime last year, and I don't see any accessible updates to it.

                              I see about SP3. Well, I'm not going to reinstall my OS in order to visit a couple sites. The transaction should be between the web browser and the remote web server without involving the OS (Internet Explorer).

                              R.i.p., Opium. Firefox still works under the same system.

                                Incorrect, there is no trasaction between web server and Internet Explorer. You are wrong!

                                Chrome, Iron and Opera are using certificates from the Windows systems certificate store, not the Internet Explorer.

                                Firefox still works under the same system.

                                Didnt you read my posts!? Ignored them!?
                                I recently said, that Firefox has, like Opera 12 (and even older) ists own certificate (from Windows independant) store!

                                I see about SP3.

                                You think using Windows XP is really a good choice? Getting no security updates and no updated certificates? Well.

                                  Sometimes security certificate problems are caused by the date on your computer being to far off. Check the date on your computer.

                                    Hi, I'm who started this discussion. Because the certificate issue I switched from Opera 20 to Firefox, but now I'm trying Opera 30 and it seems this issue has been fixed. I've not made any change in my OS, so I figure all credit must go to Opera developers. Maybe Opera has now its own certificates like Firefox?... I don't know, but in any event problem solved!
