If you can’t trust the connection to your bank, what can you do. Before you slip into a state of panic, there are two fairly typical reasons for this error message occurring. One cause of Invalid or Expired Security Certificate errors is a problem with your computer.

One of the most common causes of an Invalid or Expired Security Certificate error is the clock on your computer being wrong for some reason.

Otherwise, launch the Activity Monitor application in any of the following ways: ☞ Enter the first few letters of its name into a Spotlight search.

The anatomy of the cert The cert has a bunch of data fields but the main ones you should know about are these five: • Issuer • Validity (valid from that date to this date) • Company details • Public Key • Signature When you go to twitter.com your computer downloads the certificate and analyzes these data fields. If the name on the certificate matches the name of the domain name, twitter.com, then the browser accepts the cert and all is well. The neat thing about certificates is that even if some loser hacker stole the twitter.com certificate (and you accidentally downloaded it when you went to his malicious site: badsite.com) your browser would still reject it because it would immediately recognize the certificate name and domain name aren’t equal. Moreover, even if the owner of badsite.com tried to fool your computer by manually changing the data field in the certificate from twitter.com to badsite.com, your browser would still reject it because the checksum for the digital signature wouldn’t match the data contained inside the certificate. This is why digital certificates are used to verify identity – they virtually guarantee the integrity of the certificate and make it hard for the owner to repudiate ownership. The Bottom Line The bottom line is that if you start getting certificate errors you should try three things: • Check the system date • Reset your browser settings • Update your Root Certificates If you think about a digital certificate like a normal certificate it’ll start to make sense.
