Since few days, I tried to install the contribution PayPal IPN Module v1.0 For 2.2MS2.
I bought a SSL certificate and installed it on my website. Don't know where the location of my public certificate (*.pem) to use for signing the date and the loation of my Private key (*.pem). Ask my company where my website is and they give me the location for the two files but it's not files with .pem extension but .key and .crt .
What I have to do ? I'm so confused ...
