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  gt  server pem

What I have observed is  if you use openssl to generate certificates  it captures both the text part and the base64 certificate part in the crt file  The strict pem format says  wiki definition  that the file should start and end with BEGIN and END       pem      Privacy Enhanced Mail  Base64 encoded DER certificate    enclosed between  -----BEGIN CERTIFICATE-----  and  -----END   CERTIFICATE-----    So for some libraries  I encountered this in java  that expect strict pem format  the generated crt would fail the validation as an  invalid pem format    Even if you copy or grep the lines with BEGIN END CERTIFICATE  and paste it in a cert pem file  it should work   Here is what I do  not very clean  but works for me  basically it filters the text starting from BEGIN line      grep -A 1000 BEGIN cert crt   cert pem

Trying to upload a GoDaddy certificate to AWS I failed several times  but in the end it was pretty simple  No need to convert anything to  pem  You just have to be sure to include the GoDaddy bundle certificate in the chain parameter  e g   aws iam upload-server-certificate     --server-certificate-name mycert     --certificate-body file   try2 40271b1b25236fd1 crt     --private-key file   server key     --path  cloudfront production      --certificate-chain file   try2 gdig2 bundle crt   And to delete your previous failed upload you can do   aws iam delete-server-certificate --server-certificate-name mypreviouscert

Your keys may already be in PEM format  but just named with  crt or  key   If the file s content begins with -----BEGIN and you can read it in a text editor   The file uses base64  which is readable in ASCII  not binary format  The certificate is already in PEM format  Just change the extension to  pem   If the file is in binary   For the server crt  you would use  openssl x509 -inform DER -outform PEM -in server crt -out server crt pem   For server key  use openssl rsa in place of openssl x509   The server key is likely your private key  and the  crt file is the returned  signed  x509 certificate   If this is for a Web server and you cannot specify loading a separate private and public key   You may need to concatenate the two files  For this use   cat server crt server key  gt  server includesprivatekey pem   I would recommend naming files with  includesprivatekey  to help you manage the permissions you keep with this file

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  gt  name crt   Then I used these instructions from Trouble with Google Apps Custom Domain SSL  which were   openssl rsa -in privateKey key -text  gt  private pem openssl x509 -inform PEM -in www mydomain com crt  gt  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
