    # 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.

    #   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).

    #   Semaphore:
    #   Configure the path to the mutual exclusion semaphore the

    #   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:!aNULL

    # SSL server cipher order preference:
    # Use server priorities for cipher algorithm choice.
    # Clients may prefer lower grade encryption.  You should enable this
    # option if you want to enforce stronger encryption, and can afford
    # the CPU cost, and did not override SSLCipherSuite in a way that puts
    # insecure ciphers first.
    # Default: Off

    #   Allow insecure renegotiation with clients which do not yet support the
    #   secure renegotiation protocol. Default: Off
