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
• server.key

Answer 1

this is the best option to create .pem file

openssl pkcs12 -in MyPushApp.p12 -out MyPushApp.pem -nodes -clcerts

Answer 2

• Open terminal.
• Go to the folder where your certificate is located.
• Execute below command by replacing name with your certificate.

openssl pkcs12 -in YOUR_CERTIFICATE.p12 -out YOUR_CERTIFICATE.pem -nodes -clcerts

• Hope it will work!!

Answer 3

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

Answer 4

I was trying to go from godaddy to app engine. What did the trick was using this line:

openssl req -new -newkey rsa:2048 -nodes -keyout name.unencrypted.priv.key -out name.csr

Exactly as is, but replacing name with my domain name (not that it really even mattered)

And I answered all the questions pertaining to common name / organization as www.name.com

Then I opened the csr, copied it, pasted it in go daddy, then downloaded it, unzipped it, navigated to the unzipped folder with the terminal and entered:

cat otherfilegodaddygivesyou.crt gd_bundle-g2-g1.crt > name.crt

Then I used these instructions from Trouble with Google Apps Custom Domain SSL, which were:

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

exactly as is, except instead of privateKey.key I used name.unencrypted.priv.key, and instead of www_mydomain_com.crt, I used name.crt

Then I uploaded the public.pem to the admin console for the "PEM encoded X.509 certificate", and uploaded the private.pem for the "Unencrypted PEM encoded RSA private key"..

.. And that finally worked.
