#   Pseudo Random Number Generator (PRNG):

#   Configure one or more sources to seed the PRNG of the

#   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.

#   Point SSLCertificateFile at a PEM encoded certificate.  If

#   the certificate is encrypted, then you will be prompted for a

#   pass phrase.  Note that restarting httpd 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.)

#   Some ECC cipher suites (http://www.ietf.org/rfc/rfc4492.txt)

#   require an ECC certificate which can also be configured in

#   parallel.

SSLCertificateFile /etc/pki/tls/certs/localhost.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.)

#   ECC keys, when in use, can also be configured in parallel

SSLCertificateKeyFile /etc/pki/tls/private/localhost.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 convenience.

#SSLCertificateChainFile /etc/pki/tls/certs/server-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)

#SSLCACertificateFile /etc/pki/tls/certs/ca-bundle.crt

#   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.

#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.

#   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 sent or allowed to be 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 sent 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.

#   compact non-error SSL logfile on a virtual host basis.
