"openssl" provides commands that should be able to process the PEM 
components in-place.

For instance, if you want to extract the certificate, only, from a PEM 
file, you can:
   openssl x509 -in somecert.pem -out cert-only.pem

...and for the private key:
   openssl rsa -in somecert.pem -out key-only.pem
