SHA-1 Deprecation Plan by Browsers


PLEASE NOTE: SSL SHA-1 certificates will no longer be issued starting January 1, 2016 to comply with SHA-1 CAB/F Baseline Requirements.

If you're still using SHA-1 certificates, you should replace with SHA-2 certificates.

Google Chrome and Mozilla Firefox already stop supporting SHA1 certificates. Microsoft Edge and IE will stop supporting SHA-1 certificate by applying a security patch.



You can check your website is ready for the changes at Thawte CryptoReport

If your website currently uses a SHA-1 SSL certificate that expires later than 12/31/2016, you need to take action to protect your business:
Replace your SHA-1 certificate with SHA-256.

If your applications do not support SHA-256, we strong recommend you upgrade them as soon as possible. You can find answers to frequently asked questions here
