# This is the Apache server configuration file providing SSL support.
# It contains the configuration directives to instruct the server how to

# directives see <https://httpd.apache.org/docs/2.4/mod/mod_ssl.html>

# 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.

#   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.)
SSLCertificateFile /etc/httpd/ssl/server.crt
#SSLCertificateFile /etc/httpd/ssl/server-dsa.crt

#   Server Private Key:
#   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.)
SSLCertificateKeyFile /etc/httpd/ssl/server.key
#SSLCertificateKeyFile /etc/httpd/ssl/server-dsa.key

#   Server Certificate Chain:
#   Point SSLCertificateChainFile at a file containing the
#   concatenation of PEM encoded 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/httpd/ssl/ca.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.
#SSLCACertificatePath /etc/httpd/ssl
#SSLCACertificateFile /etc/httpd/ssl/ca-bundle.crt

#   Certificate Revocation Lists (CRL):
#   Set the CA revocation path where to find CA CRLs for client
#   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
#		 Makefile to update the hash symlinks after changes.
#SSLCARevocationPath /etc/httpd/ssl
#SSLCARevocationFile /etc/httpd/ssl/ca-bundle.crl

#   Client Authentication (Type):
#   Client certificate verification type and depth.  Types are
#   none, optional, require and optional_no_ca.  Depth is a
#   number which specifies how deeply to verify the certificate
#   issuer chain before deciding the certificate is not valid.
#SSLVerifyClient require
#SSLVerifyDepth  10

#   Access Control:
#   With SSLRequire you can do per-directory access control based
#   on arbitrary complex boolean expressions containing server
#   variable checks and other lookup directives.  The syntax is a
#   mixture between C and Perl.  See the mod_ssl documentation
#   for more details.

#			and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
#			and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"} \
#			and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
#			and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20	   ) \

#   SSL Engine Options:
#   Set various options for the SSL engine.
#   o FakeBasicAuth:
#	 Translate the client X.509 into a Basic Authorisation.  This means that
#	 the standard Auth/DBMAuth methods can be used for access control.  The
#	 user name is the `one line' version of the client's X.509 certificate.
#	 Note that no password is obtained from the user. Every entry in the user
#	 file needs this password: `xxj31ZMTZzkVA'.
#   o ExportCertData:
#	 This exports two additional environment variables: SSL_CLIENT_CERT and
#	 SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
#	 server (always existing) and the client (only existing when client
#	 authentication is used). This can be used to import the certificates
#	 into CGI scripts.
#   o StdEnvVars:
#	 This exports the standard SSL/TLS related `SSL_*' environment variables.
#	 Per default this exportation is switched off for performance reasons,
#	 because the extraction step is an expensive operation and is usually
#	 useless for serving static content. So one usually enables the
#	 exportation for CGI and SSI requests only.
#   o StrictRequire:
#	 This denies access when "SSLRequireSSL" or "SSLRequire" applied even
#	 under a "Satisfy any" situation, i.e. when it applies access is denied
#	 and no other module can change it.
#   o OptRenegotiate:
#	 This enables optimized SSL connection renegotiation handling when SSL
#	 directives are used in per-directory context.

#   SSL Protocol Adjustments:
#   The safe and default but still SSL/TLS standard compliant shutdown
#   approach is that mod_ssl sends the close notify alert but doesn't wait for
#   the close notify alert from client. When you need a different shutdown
#   approach you can use one of the following variables:
#   o ssl-unclean-shutdown:
#	 This forces an unclean shutdown when the connection is closed, i.e. no
#	 SSL close notify alert is send or allowed to received.  This violates
#	 the SSL/TLS standard but is needed for some brain-dead browsers. Use
#	 this when you receive I/O errors because of the standard approach where
#	 mod_ssl sends the close notify alert.
#   o ssl-accurate-shutdown:
#	 This forces an accurate shutdown when the connection is closed, i.e. a
#	 SSL close notify alert is send and mod_ssl waits for the close notify
#	 alert of the client. This is 100% SSL/TLS standard compliant, but in
#	 practice often causes hanging connections with brain-dead browsers. Use
#	 this only for browsers where you know that their SSL implementation
#	 works correctly.
#   Notice: Most problems of broken clients are also related to the HTTP
#   keep-alive facility, so you usually additionally want to disable
#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
#   "force-response-1.0" for this.

#   Per-Server Logging:
#   The home of a custom SSL log file. Use this when you want a
#   compact non-error SSL logfile on a virtual host basis.
