IE 與 Edge 推出更新,阻擋 SHA-1 憑證

微軟這幾天推出更新,IEEdge 將不會接受 SHA-1 憑證:「Microsoft Makes it Official, Cuts off SHA-1 Support in IE, Edge」。微軟的公告則是在「Deprecation of SHA-1 for SSL/TLS Certificates in Microsoft Edge and Internet Explorer 11」這邊。

根憑證不受影響 (所以企業自己產生的 Root CA 也不受影響):

Beginning May 9, 2017, Microsoft released updates to Microsoft Edge and Internet Explorer 11 to block sites that are protected with a SHA-1 certificate from loading and to display an invalid certificate warning. This change will only impact SHA-1 certificates that chain to a root in the Microsoft Trusted Root Program where the end-entity certificate or the issuing intermediate uses SHA-1. Enterprise or self-signed SHA-1 certificates will not be impacted, although we recommend that all customers quickly migrate to SHA-2 based certificates.
