Summary0001494: Shorten certificate lifetime to one year
Description(A) Shorten certificate lifetime to 395 days


(B) Allow the client/customer select the period of validity:
"valid 1 year (for websites mandatory)" 395 days
"valid 2 years (not suitable for websites)" 820 days
"valid 5 years (not suitable for websites)" 1900 days
Additional InformationThe maximum validity of certificates for proof of identity on the web will be further reduced – in the next step to one year. Apple declared that Safari will only accept certificates issued after September 1, 2020 if they are not valid for more than one year.

Now Mozilla and Google are following suit and creating facts. In the past, terms of 5 years were not unusual. Currently, certificates may still be issued for 2 years (more precisely: 825 days — i.e. plus some grace period). With the renewed tightening, Chrome, for example, delivers an ERR_CERT_VALIDITY_TOO_LONG if a certificate was issued after September 1, 2020 and is valid for more than 398 days.
