The original submission also says StartCom sent an email to all their former customers -- including customers of their free StartSSL certificates -- announcing their intentions. As you are surely aware, the browser makers distrusted StartCom around a year ago and therefore all the end entity certificates newly issued by StartCom are not trusted by default in browsers.
The browsers imposed some conditions in order for the certificates to be re-accepted. While StartCom believes that these conditions have been met, it appears there are still certain difficulties forthcoming. Considering this situation, the owners of StartCom have decided to terminate the company as a Certification Authority as mentioned in Startcoms website.
StartCom will stop issuing new certificates starting from January 1st, 2018 and will provide only CRL and OCSP services for two more years. StartCom would like to thank you for your support during this difficult time.
