#
# This is the Apache server configuration file providing SSL support using.
# the mod_nss plugin.  It contains the configuration directives to instruct
# the server how to serve pages over an https connection.
# 
# 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.  
#

#
# When we also provide SSL we have to listen to the 
# standard HTTP port (see above) and to the HTTPS port
#
# Note: Configurations that use IPv6 but not IPv4-mapped addresses need two
#       Listen directives: "Listen [::]:8443" and "Listen 0.0.0.0:443"
#
Listen 8443

##  SSL Global Context

##  the main server and all SSL-enabled virtual hosts.

#   Configure the SSL Session Cache. 
#   NSSSessionCacheSize is the number of entries in the cache.

# 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. Those platforms usually also provide a non-blocking
# device, /dev/urandom, which may be used instead.
#
# This does not support seeding the RNG with each connection.

#   SSL Protocol:
#   Cryptographic protocols that provide communication security.
#   NSS handles the specified protocols as "ranges", and automatically
#   negotiates the use of the strongest protocol for a connection starting
#   with the maximum specified protocol and downgrading as necessary to the
#   minimum specified protocol that can be used between two processes.
#   Since all protocol ranges are completely inclusive, and no protocol in the
#   middle of a range may be excluded, the entry "NSSProtocol SSLv3,TLSv1.1"
#   is identical to the entry "NSSProtocol SSLv3,TLSv1.0,TLSv1.1".
NSSProtocol TLSv1.0,TLSv1.1,TLSv1.2

#   SSL Certificate Nickname:
#   The nickname of the RSA server certificate you are going to use.
NSSNickname Server-Cert

#   SSL Certificate Nickname:
#   The nickname of the ECC server certificate you are going to use, if you
#   have an ECC-enabled version of NSS and mod_nss
#NSSECCNickname Server-Cert-ecc

#   Server Certificate Database:
#   The NSS security database directory that holds the certificates and
#   keys. The database consists of 3 files: cert8.db, key3.db and secmod.db.
#   Provide the directory that these files exist.
NSSCertificateDatabase /etc/apache2/nssdb

#   Database Prefix:
#   In order to be able to store multiple NSS databases in one directory
#   they need unique names. This option sets the database prefix used for
#   cert8.db and key3.db.
#NSSDBPrefix my-prefix-

#   Client Authentication (Type):
#   Client certificate verification type.  Types are none, optional and
#   require.
#NSSVerifyClient none

#
#   Online Certificate Status Protocol (OCSP).
#   Verify that certificates have not been revoked before accepting them.
#NSSOCSP off

#
#   Use a default OCSP responder. If enabled this will be used regardless
#   of whether one is included in a client certificate. Note that the
#   server certificate is verified during startup.
#
#   NSSOCSPDefaultURL defines the service URL of the OCSP responder
#   NSSOCSPDefaultName is the nickname of the certificate to trust to
#       sign the OCSP responses.

#NSSOCSPDefaultURL http://example.com/ocsp/status
#NSSOCSPDefaultName ocsp-nickname

#   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_nss documentation
#   for more details.
#<Location />
#NSSRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
#            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       ) \
#           or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
#</Location>

#   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 "NSSRequireSSL" or "NSSRequire" 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.

#   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.
