Maximum Certificate Lifetime Drops to 825-days in 2018
The CA/Browser Forum has taken a progressive step by reducing SSL/TLS certificate lifetimes from 39 months (~1185 days) to 27 months (stated as 825 days for computational ease). The move to an 825-day maximum certificate validity period for all types of certificates (DV, OV, and EV) will be effective for all new certificates purchased on or after of March 1, 2018. Why Change the Certificate Lifetime? The goal of reducing the lifetime is it allows certificates to be changed more frequently.
