Microsoft has announced a new policy for
Certificate Authorities (CAs)
that deprecates the use of the SHA1 algorithm in SSL and code signing certificates, in favor of SHA2. The policy affects CAs who are members of the Windows Root Certificate Program who issue publicly trusted certificates. It will allow CAs to continue to issue SSL and code signing certificates until January 1 2016, and thereafter issue SHA2 certificates only.
Windows PKI blog, "SHA1 Deprecation Policy". https://docs.microsoft.com/en-us/security-updates/securityadvisories/2017/4010323 , December 12/17/2013
Key Dates:
- 1 Jan 2016 – CAs must stop issuing SHA1 certificates
- 1 Jan 2017 – Windows will stop accepting SHA1 SSL certificates
- 1 Jan 2016 – Windows will stop accepting SHA1 code signing certificates without time stamps
Details:
For SSL certificates, Windows will stop accepting SHA-1 end-entity certificates by January 1, 2017. This means for Windows, a three-year SHA-1 certificate issued after January 1, 2014 won’t work after that date. Same for a two-year SHA-1 certificate issued after January 1, 2015, and a one-year SHA-1 certificate issued after January 1, 2016. It’s time to plan ahead when ordering or renewing your certificates.
For code signing certificates, Windows will stop accepting SHA-1 code signing certificates without time stamps after January 1, 2016.
Internet Explorer and new versions of Mac OSX, Firefox, Chrome, Opera, Safari, Java and Adobe Acrobat/Reader all support SHA-2
Some enterprises might be running a non-browser application that does not support SHA-2. If you are unaware, you need to do some investigation or testing to see if your system supports SHA-2 and consider your migration plan.
