About this update

After you apply this update, the signature and hash algorithm combinations for RSA\SHA512 and ECDSA\SHA512 are enabled for the Transport Layer Security (TLS) 1.2 protocol. This means that you can now use SHA512 certificates on your computer.

If you currently use SHA512 certificates, and do not have this update installed, you may have problems in one or more of the following scenarios by using TLS 1.2:

  • Internet Protocol security (IPsec) stand-alone

  • IPSec with DirectAccess

  • Microsoft Lync Server 2013

  • Remote Desktop Services (RDP)

  • SSL websites

  • SSL based VPN

  • Web applications


Notes

  • RSA\SHA512 means that the RSA signature algorithm is combined with SHA512 hash algorithm.

  • ECDSA\SHA512 means that the Elliptic Curve Digital Signature Algorithm (ECDSA) is combined with SHA512 hash algorithm.
