As of April 1, 2022, the requirements for email certificates will be tightened. SwissSign will stop issuing email certificates with a three-year validity in March 2022. Only email certificates with a validity of one or two years will then be available. Certificates with a validity of three years issued before April 1 will remain valid after the cut-off date and will not be revoked.
The tightening of email certificate requirements stems from a new Rootstore Policy, or updated Root Certificate Program, that Apple recently released. The policy defines which requirements providers of certificate services have to fulfill in order to be recognized as trustworthy by Apple.
