Validity Foxit: The Certificate Has Exceeded The Time Of
“Time is just another field in the certificate. And fields can be edited—if you hold the master key.”
“So?”
Every expired certificate, every dead signature, was a backdoor. And someone had just kicked them all open. the certificate has exceeded the time of validity foxit

The Bradshaw contract now displayed a new expiration date for the certificate: December 31, 2099. Someone—or something—had just extended the validity of a cryptographic key that had been dead for thirty-seven years. “Time is just another field in the certificate
