Compilation

+

+ mod_gnutls uses the "configure/make/make install" + mechanism common to many Open Source programs. + Most of the dirty work is handled by either configure or + Apache's apxs utility. If you have built Apache modules before, there + shouldn't be any surprises for you. +

+

+ The interesting options you can pass to configure are:

+
    +
  • --with-apxs=/path/to/apache/dir/bin/apxs +

    + This option is used to specify the location of the + apxs utility that was installed as part of apache. + Specify the location of the binary, not the directory + it is located in. +

    +
    • +
  • --with-libgnutls=PATH +

    Full path to the libgnutls-config program.

    +
    • +
  • --with-apr-memcache=PREFIX +

    Prefix to where apr_memcache is installed.

    +
    • +
  • --help +

    Provides a list of available configure options.

    +
    • +
+
./configure --with-apxs=/usr/sbin/apxs2 --with-libgnutls=/usr
+make
+make install
+
+
+
+

Integration into Apache

+

To activate mod_gnutls Just add

+ LoadModule gnutls_module modules/mod_gnutls.so + to your httpd.conf and restart Apache. +

+
+
+

Examples

+

Some example configuration and the exported variables to scripts can be + found in the following sections:

Standard SSL Example

+

The following is an example of standard SSL Hosting, using one IP Addresses for each virtual host:

+
+# Load the module into Apache.
+LoadModule gnutls_module modules/mod_gnutls.so
+
+GnuTLSCache dbm /var/cache/www-tls-cache
+GnuTLSCacheTimeout 500

Server Name Indication Example

+

mod_gnutls can also use 'Server Name Indication', as specified in +RFC 3546. This allows hosting many SSL Websites, with a Single IP Address. Currently all the recent +browsers support this standard. Here is an example, using SNI: +

+
+# Load the module into Apache.
+LoadModule gnutls_module modules/mod_gnutls.so
+
+# With normal SSL Websites, you need one IP Address per-site.
+Listen 1.2.3.1:443
+# This could also be 'Listen *:443',
+# just like '*:80' is common for non-https
+
+# No caching. Enable session tickets. Timeout is still used for
+# ticket expiration.
+GnuTLSCacheTimeout 600
+
+# This tells apache, that for this IP/Port combination, we want to use
+# Name Based Virtual Hosting.  In the case of Server Name Indication,
+# it lets mod_gnutls pick the correct Server Certificate.

Performance Issues

+

mod_gnutls by default uses conservative settings for the + server. You can fine tune the configuration to reduce the load on a busy + server. The following examples do exactly this. +

+
+# Load the module into Apache.
+LoadModule gnutls_module modules/mod_gnutls.so
+
+# Using 4 memcache servers to distribute the SSL Session Cache.
+GnuTLSCache memcache "mc1.example.com mc2.example.com mc3.example.com mc4.example.com"

GnuTLSCache

+ + + + + + + + + + + + + + + + + +
Description:Configure SSL Session Cache
Syntax:GnuTLSCache [dbm|gdbm|memcache|none] [path|server list|-]
Default:dbm "conf/gnutls_cache"
Context: + global config +
+

This directive configures the SSL Session Cache for mod_gnutls. + This could be shared between machines of different architectures. +

+
+
dbm
+
+ Uses the default Berkeley DB backend of APR DBM to cache SSL Sessions results. The argument is a relative or absolute path to be used + as the DBM Cache file. This is compatible with most operating systems. +
+ +
gdbm
+
+ Uses the GDBM backend of APR DBM to cache SSL Sessions results. The argument is a relative or absolute path to be used + as the DBM Cache file. +
+ +
memcache
+
+ Uses a memcached server to cache the SSL Session. + The argument is a space separated list of servers. If no port number is supplied, + the default of 11211 is used. This can be used to share a session cache between all servers in a cluster. +
+ +
None
+
+ Turns off all caching of SSL Sessions. This can significantly reduce the performance of mod_gnutls + since even followup connections by a client must renegotiate + parameters instead of reusing old ones. +
+
+Example Usage: +
GnuTLSCache memcache "10.0.0.1 10.0.0.2 10.0.0.3"
+
+ +
+

+

This directive controls the use of SSL Client Certificate Authentication. If used in the .htaccess + context, it can force TLS re-negotiation. +

+
+
ignore
+
mod_gnutls will ignore the contents of any SSL Client Certificates sent. + It will not request that the client sends a certificate. +
+ +
request
+
The client certificate will be requested, but not required. The Certificate will be validated if sent. The output of the validation status will be stored in the SSL_CLIENT_VERIFY environment variable and can be "SUCCESS", "FAILED" or "NONE".
+ +
require
+
A Client certificate will be required. Any requests without a valid client certificate will be denied. The SSL_CLIENT_VERIFY environment variable will only be set to "SUCCESS".

You can generate this file using "certtool --generate-privkey --bits 512". These parameters should not contain key of longer of 512 bits (due to the export restrictions). If not set mod_gnutls will not negotiate the 'EXPORT' ciphersuites. It is recommended not to enable those ciphersuites. If you do make sure you regenerate this file at every few hours. +

+Example Usage: +
GnuTLSRSAFile conf/ssl/rsaparams
+
+ +
+

GnuTLSSRPPasswdFile

+ + + + + + + + + + + + + + + + + +

Syntax:GnuTLSSRPPasswdFile file-path
Default:none
Context: + server config, + virtual host. +
+

Takes an absolute or relative path to an SRP password file. This is the same format as used in libsrp. You can generate such file using the command "srptool --passwd /etc/tpasswd --passwd-conf /etc/tpasswd.conf -u test" to set a password for user test. This password file holds the username, a password verifier and the dependency to the SRP parameters. +

+Example Usage: +
GnuTLSSRPPasswdFile conf/ssl/tpasswd
+
+ +
+

GnuTLSSRPPasswdConfFile

+ + + + + + + + + + + + + + + + + +
Description:Set to the SRP password.conf file for SRP ciphersuites.
Syntax:GnuTLSSRPPasswdConfFile file-path
Default:none
Context: + server config, + virtual host. +
+

Takes an absolute or relative path to an SRP password.conf file. This is the same format as used in libsrp. You can generate such file using the command "srptool --create-conf /etc/tpasswd.conf". This file holds the SRP parameters and is associate with the password file (the verifiers depends on these parameters). +

+Example Usage: +
GnuTLSSRPPasswdConfFile conf/ssl/tpasswd.conf
+
+ +
+

GnuTLSPriorities

+ + + + + + + + + + + + + + + + + +
Description:Set the allowed ciphers, key exchange algorithms, MACs and + compression methods.
Syntax:GnuTLSPriorities +cipher0:+cipher1:...:+cipherN
Default:none
Context: + server config, + virtual host. +
+

Takes a semi-colon separated list of ciphers, key exchange methods + Message authentication codes and compression methods to enable. The + allowed keywords are specified in the gnutls_priority_init() + function of GnuTLS. It's documentation can be found at + Core + GnuTLS functions. +

+ In brief you can specify a set of ciphersuites from the choices: +

    +
  • NONE: The empty list.
    • +
  • EXPORT: A list with all the supported cipher combinations + including the "EXPORT" strength algorithms.
    • +
  • PERFORMANCE: A list with all the secure cipher combinations + sorted in terms of performance.
    • +
  • NORMAL: A list with all the secure cipher combinations + sorted with respect to security margin (subjective term).
    • +
  • SECURE: A list with all the secure cipher combinations including the + 256-bit ciphers sorted with respect to security margin.
    • +
+ Additionally you can add or remove algorithms using the "+" and "!" + prefixes respectively. That is in order to disable the ARCFOUR cipher + from the "NORMAL" set you can use the string + NORMAL:!ARCFOUR-128. Other options such as the protocol + version and the compression method can be specified using the + VERS- and COMP- prefixes. So in order to + remove or add a specific TLS version from the "NORMAL" set use + NORMAL:!VERS-SSL3.0. To enable + zlib compression use NORMAL:+COMP-DEFLATE. + However it is recommended not to add compression at this level. + With the "NONE" set, in order to be usable, you have to specify a complete + set of combinations of protocol versions, cipher algorithms + (AES-128-CBC), key exchange algorithms (RSA), message authentication + codes (SHA1) and compression methods (COMP-NULL). +

+ All the supported algorithms are: +

    +
  • Ciphers: AES-256-CBC, AES-128-CBC, CAMELLIA-256-CBC, + CAMELLIA-128-CBC, ARCFOUR-128, 3DES-CBC, ARCFOUR-40
    • +
  • Key exchange methods: RSA, DHE-RSA, DHE-DSS, SRP, SRP-RSA, + SRP-DSS, ANON-DH
    • +
  • Message authentication codes: SHA1, MD5
    • +
  • Compression methods: COMP-DEFLATE, COMP-NULL
    • +
  • Protocol versions: VERS-TLS1.1, VERS-TLS1.0, VERS-SSL3.0
    • +
+

+

The special keyword "%COMPAT" will disable some security features + such as protection against statistical attacks to ciphertext data in + order to achieve maximum compatibility (some broken mobile clients need + this). +

+Example Usage: +
GnuTLSPriorities NORMAL:!AES-256-CBC:!DHE-RSA
+
GnuTLSPriorities EXPORT:!VERS-TLS1.0:+COMP-DEFLATE:+CTYPE-OPENPGP
+
