Hi Jody,

Is this for  SSL certificate only or for all certificates including Code signing certificate and client certificate?
Please clarify, thanks.

Many of our partners in the industry told us that, because of the end of the year holiday lockdown periods, a January date was effectively a November date. Because of this, Microsoft has reconsidered it’s position, and we have decided to move the effective date of the SHA-1 deprecation to Tuesday, February 14, 2017.  Please see http://aka.ms/sha1 for more information.
