How to get .pem file from .key and .crt files?

Question

How can I create a PEM file from an SSL certificate?

These are the files that I have available:

• .crt
• server.csr

Answer 1

A pem file contains the certificate and the private key. It depends on the format your certificate/key are in, but probably it's as simple as this:

cat server.crt server.key > server.pem
