	# Pseudo Random Number Generator (PRNG):
	# Configure one or more sources to seed the PRNG of the SSL library.
	# The seed data should be of good random quality.
	# WARNING! On some platforms /dev/random blocks if not enough entropy
	# is available. This means you then cannot use the /dev/random device
	# because it would lead to very long connection times (as long as
	# it requires to make more entropy available). But usually those
	# platforms additionally provide a /dev/urandom device which doesn't
	# block. So, if available, use this one instead. Read the mod_ssl User
	# Manual for more details.
