# 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.

# Pass Phrase Dialog:
# Configure the pass phrase gathering process.
# The filtering dialog program (`builtin' is a internal
# terminal dialog) has to provide the pass phrase on stdout.

# Inter-Process Session Cache:
# Configure the SSL Session Cache: First the mechanism
# to use and second the expiring timeout (in seconds).
# (The mechanism dbm has known memory leaks and should not be used).

# Configure the path to the mutual exclusion semaphore the
# SSL engine uses internally for inter-process synchronization.
# (Disabled by default, the global Mutex directive consolidates by default
# this)

# SSL Cipher Suite:
# List the ciphers that the client is permitted to negotiate. See the
# ciphers(1) man page from the openssl package for list of all available
# options.
# Enable only secure ciphers:
SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5

# Speed-optimized SSL Cipher configuration:
# If speed is your main concern (on busy HTTPS servers e.g.),
# you might want to force clients to specific, performance
# optimized ciphers. In this case, prepend those ciphers
# to the SSLCipherSuite list, and enable SSLHonorCipherOrder.
# Caveat: by giving precedence to RC4-SHA and AES128-SHA
# (as in the example below), most connections will no longer
# have perfect forward secrecy - if the server's key is
# compromised, captures of past or future traffic must be
# considered compromised, too.
