In the paypal topic Secure Your HTML Payment Buttons there is described how to create a my-prvkey.pem , my-pubcert.pem and how to download paypal_cert_pem.txt .
Now in the part Download and Configure EWP software for Manually Created Buttons:
3.Copy your private key, public certificate, p12 file and the PayPal public certificate to the same folder on your web server where the software is located.
they are asking for a p12 file.
I found how to create p12 from pem, but I am confused what pem files to include.
Should I include all this files?
my-prvkey.pem
my-pubcert.pem
paypal_cert_pem.txt
