The Road to 47 Days: Automating the PSU Certificate Lifecycle
The era of the "annual certificate" is over. Following the adoption of Ballot SC-081v3, we have entered a phased reduction of SSL/TLS validity periods: dropping to 200 days in March 2026, 100 days in 2027, and finally 47 days by 2029. Crucially, the Domain Control Validation (DCV) reuse period is shrinking even further—slashing down to just 10 days by the end of this transition. For Penn State's distributed IT environment, this means proving domain ownership is no longer a "once a year" task, but a continuous requirement.
