Hi All. Thanks for the help. The certificate is a ".crt.pem". Key is a ".key". Anyhow, earlier I was thinking of saving the certificate+key in a file, where double-quotes were delimiters. But, I have rejected that idea; instead saving them in their respective files :) So, the question becomes obsolete. Anyhow, I am thanks (and sorry at the same time) for everyone's time.
