Are You Ready for the Death of SHA-1?

May 4, 2016

Perhaps the better question is: What is SHA-1? Essentially, SHA-1 is a cryptographic algorithm that is used to generate secure certificates. I previously wrote that browsers would begin to drop accepting SHA-1 as a secure transmission method in early 2016. We now have more news of the deprecation of SHA-1. Microsoft has announced that with the delivery of the Windows 10 Anniversary Update, scheduled for summer 2016 release, both Internet Explorer (IE) and Edge will no longer show the locked icon to indicate a secure website. The two browsers won't actually block websites signed with SHA-1 until February 14, 2017. How fitting that SHA-1 will die for Microsoft browsers on Valentine's Day.
