Installing your SSL Certificate
The easiest way to install the SSL certificate is to contact your host, developer or admin. Most of the time your host will install it for free. You can also view ssl certificate installation tutorials depending on your server setup.
If you use IIS and need a PFX file then follow the instructions in the following link to convert the certificate and private key file into a .PFX file - http://stackoverflow.com/a/17284371 (Install openssl and run openssl pkcs12 -export -out "certificate_combined.pfx" -inkey "private.key" -in "certificate.crt" -certfile ca_bundle.crt in a command prompt with path set to location of downloaded certificate files or use https://www.digicert.com/util/)
If you have any issues with certain browsers like Android not recognizing the certificate then test your server SSL configuration on SSL Labs and fix any errors shown.
If you get an error saying the certificate and key do not match then contact your host asking for the key type they accept. If they require the old RSA key type then download OpenSSL and execute the following command on the private key file: openssl rsa -in private.key -out private_rsa.key
If you need the private key in PEM format then install OpenSSL and run the following on the private key file: "openssl rsa -in private.key -text > private.pem"
If you need the multiple certificates in PEM format or everything in PEM format then first convert your private key to PEM format above then follow these instructions.
