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

I needed to do this for an AWS ELB. After getting beaten up by the dialog many times, finally this is what worked for me:

openssl rsa -in server.key -text > private.pem
openssl x509 -inform PEM -in server.crt > public.pem

Edit: As @floatingrock says

With AWS, don't forget to prepend the filename with file://. So it'll look like:

 aws iam upload-server-certificate --server-certificate-name blah --certificate-body file://path/to/server.crt --private-key file://path/to/private.key --path /cloudfront/static/
