Guidelines for replacing SHA-1 with SHA-2 certificates on Thawte Certificate Center (TCC)


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.

Thawte recommends the following:

  1. Identify certificates that have a SHA-1 algorithm using the Thawte 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 SO13487.
