##  SSL Global Context
##
##  All SSL configuration in this context applies both to
##  the main server and all SSL-enabled virtual hosts.
##

# These are the configuration directives to instruct the server how to
# serve pages over an https connection. For detailing information about these
# directives see <URL:https://httpd.apache.org/docs/2.4/mod/mod_ssl.html>
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.

# This global SSL configuration is ignored if 
# "SSL" is not defined, or if "NOSSL" is defined.

	#   network-mounted drives, so in that case you need to use the dbm method.

	#   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.

	#   SSL Cipher Suite:
	#   List the ciphers that the client is permitted to negotiate.
	#   See the mod_ssl documentation for a complete list.
	#   The magic string "DEFAULT_SUSE" expands to an openssl defined
	#   secure list of default ciphers.

	#   SSLHonorCipherOrder
	#   If SSLHonorCipherOrder is disabled, then the client's preferences
	#   for chosing the cipher during the TLS handshake are used.
	#   If set to on, then the above SSLCipherSuite is used, in the order
	#   given, with the first supported match on both ends.

	#   Server Certificate:
	#   Point SSLCertificateFile at a PEM encoded certificate.  If
	#   the certificate is encrypted, then you will be prompted for a
	#   pass phrase.  Note that a kill -HUP will prompt again.  Keep
	#   in mind that if you have both an RSA and a DSA certificate you
	#   can configure both in parallel (to also allow the use of DSA
	#   ciphers, etc.)

	#   If the key is not combined with the certificate, use this
	#   directive to point at the key file.  Keep in mind that if
	#   you've both a RSA and a DSA private key you can configure
	#   both in parallel (to also allow the use of DSA ciphers, etc.)

	#   Server Certificate Chain:
	#   Point SSLCertificateChainFile at a file containing the
	#   concatenation of PEM encoded intermediate CA
	#   certificates which form the certificate chain for the
	#   server certificate. Alternatively the referenced file
	#   can be the same as SSLCertificateFile when the CA
	#   certificates are directly appended to the server
	#   certificate for convinience.
	#SSLCertificateChainFile /etc/apache2/ssl.crt/chain.crt

	#   Certificate Authority (CA):
	#   Set the CA certificate verification path where to find CA
	#   certificates for client authentication or alternatively one
	#   huge file containing all of them (file must be PEM encoded)
	#   Note: Inside SSLCACertificatePath you need hash symlinks
	#         to point to the certificate files. Use the provided
	#         Makefile to update the hash symlinks after changes.

	#   authentication or alternatively one huge file containing all
	#   of them (file must be PEM encoded)
	#   Note: Inside SSLCARevocationPath you need hash symlinks
	#         to point to the certificate files. Use the provided
