		# this list is basically a manually-defined, filtered/reordered list
		# based on the recommendations from:
		#   https://hynek.me/articles/hardening-your-web-servers-ssl-ciphers/
		#   http://unhandledexpression.com/2013/01/25/5-easy-tips-to-accelerate-ssl/
		#
		# Modifications include removing ECDSA, disabling almost all non-ephemeral
		# key exchange ciphersuites to strongly prefer perfect forward secrecy
		# (and only leave alternative as a fallback), removing fallbacks that
		# wouldn't realistically happen in real browsers.
		#
		# We end up with a list of 12 ciphersuites: 4 TLS 1.2 ciphersuites, 4
		# fallbacks with PFS, then 4 weaker fallbacks for compatibility.
		# The low number of suites improves TLS handshake speed.
		#
		# Expanded list: https://gist.github.com/mtigas/8591092/raw/gistfile1.txt
		#
		# If you don't need to support IE WinXP (or older) clients you can remove
		# the weak fallbacks after DHE-RSA-AES128-SHA to force PFS ciphersuites
		# for all clients and protect against downgrade attacks.
		#
		# For performance, AES256 ciphersuites can be removed, too. (Leaves 4 or 7
		# ciphersuites.)
