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

#
#   Some MIME-types for downloading Certificates and CRLs
#
AddType application/x-x509-ca-cert .crt
AddType application/x-pkcs7-crl    .crl

#   Pass Phrase Dialog:
#   Configure the pass phrase gathering process.
#   The filtering dialog program (`builtin' is a internal
#   terminal dialog) has to provide the pass phrase on stdout.
SSLPassPhraseDialog  builtin

#   Inter-Process Session Cache:
#   Configure the SSL Session Cache: First the mechanism 
#   to use and second the expiring timeout (in seconds).
#   (The mechanism dbm has known memory leaks and should not be used).
#SSLSessionCache         dbm:${APACHE_RUN_DIR}/ssl_scache
SSLSessionCache        shmcb:${APACHE_RUN_DIR}/ssl_scache(512000)
SSLSessionCacheTimeout  300

#   Semaphore:
#   Configure the path to the mutual exclusion semaphore the
#   SSL engine uses internally for inter-process synchronization. 
SSLMutex  file:${APACHE_RUN_DIR}/ssl_mutex

#   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:MEDIUM:!aNULL:!MD5
SSLCipherSuite ALL:!aNULL:!eNULL:!LOW:!EXP:!RC4:!3DES:+HIGH:+MEDIUM
# Other possible ciphersuite (requires wheezy-version of apache2 at least)
 #SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS"

#   Speed-optimized SSL Cipher configuration:
#   If speed is your main concern (on busy HTTPS servers e.g.),
#   you might want to force clients to specific, performance
#   optimized ciphers. In this case, prepend those ciphers
#   to the SSLCipherSuite list, and enable SSLHonorCipherOrder.
#   Caveat: by giving precedence to RC4-SHA and AES128-SHA
#   (as in the example below), most connections will no longer
#   have perfect forward secrecy - if the server's key is
#   compromised, captures of past or future traffic must be
#   considered compromised, too.
#SSLCipherSuite RC4-SHA:AES128-SHA:HIGH:MEDIUM:!aNULL:!MD5
SSLHonorCipherOrder on

# enable only secure protocols: SSLv3 and TLSv1, but not SSLv2
#SSLProtocol all -SSLv2
SSLProtocol all -SSLv2 -SSLv3

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

# Whether to forbid non-SNI clients to access name based virtual hosts.
# Default: Off
SSLStrictSNIVHostCheck Off
