Guidelines for replacing SHA-1 with SHA-2 certificates on RapidSSL


Major browsers including Google Chrome, Microsoft Edge and Mozilla Firefox will stop supporting these certificates which may mean no access to web sites with SHA-1 certificate.

RapidSSL recommends the following:

  1. Identify certificates that have a SHA-1 algorithm using the Installation Checker
  2. Replace any SHA-1 certificates that expire beyond December 31 2015 with SHA-2 certificates at no additional cost. For more information, please refer to Knowledge Center article SO5757.

Here are some additional resources for your reference:
