Running windows server 2008R2 was told I have to update to SHA-2 from SHA-1.  Found Microsoft article that if you are using automatic windows updates the patch should already be on the server.  All my updates are current but there is no KB2949927 on my installed updates list.

Is there a way for me to confirm that?

I found this statement.   What does it mean it's up to the individual applications to implement support?

Starting with Windows Vista and Server 2008, the Cryptography Next Generation (CNG) Suite B algorithms (including SHA2) are included in the operating system. It is worth noting that even though the algorithms are available, it is up to the individual applications to implement support.

This one is saying it does not have it unless you have the patch.  I can't find a patch that was installed KB 2949927.

It just means they have to have interfaced with sha2 in their code instead of some other algorithm.

So you recommend I just move forward and install the SHA-2 certificate?  I have a deadline of December 31 and they just told me this morning it had to change.
