(Node.js) Load Certificate (.cer) and Private Key (.pvk) generated from makecert

See more Certificates Examples

Demonstrates how to load a certificate (.cer) and private key (.pvk) from the files produced by makecert, such as in the following command:

makecert -sv mycertificate.pvk -n "CN=My Simple Certificate" mycertificate.cer -sky Exchange
