As an exercise for class, I'm creating a class that manages user sessions.

Say I buy a prepaid sim-card with 3g data and put it in a used 3g modem (dongle) or a used smartphone and then create a Hotspot.

If a certificate has a limited duration of, say 5 years, but it gets somehow compromised after 2 years, waiting the 3 remaining years for it to get invalid is not a real solution to the breach problem. (3 years is eternity in IT, I guess)
