Question

I have used openssl to create a .key and .cer file in pem format (you can read them). Now I want to create .pfx file from them. I have read openssl doumentation it says some

Answer 1

The certificate.cer is your public key and the CACert.cer file (as it names suggest) is the public key of a CA (maybe the one who has signed your certificate).

The -in switch specifies input certificate to embed in output file

The -inkey switch specifies the key file you've generated using OpenSSL

The -out switch tells the openssl your desired name for output file

The -certfile is used to specify additional certificates to add to the output pfx file (it could be ignored)
