Is there a way for me to confirm that?

I found this statement. &nbsp; What does it mean it's up to the individual applications to implement support?<br />
<br />
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.

<div>
This one is saying it does not have it unless you have the patch. &nbsp;I can't find a patch that was installed KB 2949927.<br />

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


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

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
