@onalante-msft,
This change introduces an error for me. I am using this EST Server, and the commit before 292 works fine.

When I use this commit, my EST fails with a EST_ERR_BAD_PKCS10 error.

Here are the iotedge log files below:

Cisco's EST server does not accept unchunked base64 inputs since it does not set BIO_FLAGS_BASE64_NO_NL (pertinent issue). Previously, we would PEM-encode and manually strip the header and footer from the CSR, which would produce output with the appropriate chunk size for the server. This commit switches to an unchunked base64 encoding of the DER bytes1.

libest might be popular enough to be worth supporting despite its bug. We could artificially split the String ourselves?
