Cartegraph recommends placing SSL certificates on both the Web and Application servers. Use a wildcard SSL certificate because the certificate secures your website URL, and an unlimited number of its subdomains. For more information, http://support.godaddy.com/help/article/567/what-is-a-wildcard-ssl-certificate.
Before you purchase a certificate, generate a Certificate Signing Request (CSR) from the server. Repeat this on every server you want to get a different certificate for. Click the following link for Go Daddy’s instructions on how to get the CSR from IIS 8:
Certificates must be signed using a SHA256 or better signature hash algorithm, with either a 2048 bit or greater RSA key or a 256 bit or greater Elliptic-Curve (ECC) key.
These are the accepted ciphers:
Cartegraph recommends purchasing certificates from Go Daddy, Digicert, Trustwave, Geotrust, or similar vendor.
