Implement the functionality of a simple CA: read in a CA certificate,
the associated private key, and a PKCS #10 certificate request. Sign the
request and print out the new certificate.
File names are hardcoded for simplicity.
cacert.pem: The CA's certificate (perhaps created by self_sig)
caprivate.pem: The CA's private key
req.pem: The user's PKCS #10 certificate request
