Last week at the 49th CA/Browser Forum, a voluntary consortium of certification authorities, Apple announced that it’ll stop allowing HTTPS certificates on Safari with more than 13 months of validity, later this year, according to TNW.
Any certificate issued after September 1, with more than 398 days of validity, will be rejected by Apple‘s browser. That means, when you visit a site with such a certificate, you’ll see a privacy warning. However, as a developer, if your website’s certificate was issued prior to Sept. 1, you won’t be affected, TNW adds.
