HealthVault Platform SSL Certificate Update!

HealthVault Service communications occur via schematized XML in the body of an HTTP request over a TLS Connection [RFC2818].

Our current platform SSL certificate expires on July 4, 2013. Consequently, we are issuing a replacement certificate with anticipated deployment on July 2, 2013.

The new certificate derives trust from VeriSign’s root certificate as illustrated below. You may confirm the validity of the new certificate via VeriSign’s published root certificate page at





We anticipate that your application hosting environment will already have trust established with VeriSign’s certificate chain. If this is not the case and application failures do occur, you can install the VeriSign root certificate using the instructions provided here. TechNet instructions for Microsoft specific host-servers are provided here.
