We recently completed a scan on all of the certificates we have issued. This scan revealed there is still a large number of certificates utilising SHA-1. For more details about the effects of continuing to use SHA-1 please refer to Deprecation of SHA-1 and moving to SHA-2.
We will shortly be sending out emails to resellers with details of which certificates have been issued that are still using SHA-1. As the reseller it is your responsibility to ensure end users are aware of the implications of using SHA-1 and that they replace their certificates as soon as possible. We will not be sending emails to the end customer.
Servertastic will also be sending out emails to affected direct customers.
