Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Httpd Wiki" for change notification.

The "SettingUpModSSL" page has been changed by jmcg.
The comment on this change is: step one.. Get people interested to fill in the blanks..

--------------------------------------------------

-   Apache httpd with SSL (https, Secure Socket Layer)
+ Following Eric Covener's advise from
  
- This howto explains how to setup Apache httpd with ssl (https) for use with shopping carts,
payment gateways or other secure systems.
+ http://www.mail-archive.com/docs@httpd.apache.org/msg07081.html
  
+ I'm using this space to kick-off an SSL How-to, which we will use to replace the current,
highly out-dated one.
- Requirements
- Explanation of requirements.
  
+ In the first step I'll just fill in the titles. I really hope for some participation here
:)
+ Please also take into consideration features from 2.4, such as [[http://httpd.apache.org/docs/trunk/mod/mod_ssl.html#sslocspenable|OSCP]]
-    1. Root access or appropriate sudo privileges on the system.
-    2. Registered domain and access to dns/hosting settings.
-    3. Properly configured and working httpd setup.
  
- Doing the Work
  
- Basic description of what will be done and what is expected.
+ = create a (self-signed) certificate or certificate request =
  
-    1. Install httpd and openssl and generate key file for your new ssl certificate. While
you can generate a non-encrypted key, the point here is security, so we'll be generating an
encrypted key. Both the private key and the certificate are required to enable SSL:
  
+ = add a listen directive =
-       Install the httpd and openssl packages (see the documentation that comes with your
Linux distribution).
-       openssl genrsa -des3 -out www.example.com.key 2048
-       (Make sure to keep your passphrase in a secure location, not on your server. You'll
need this each time you start/restart apache http.)
  
-    2. Generate CSR (Certificate Signing Request) to give to your SSL certificate authority:
+ make sure Listen 443 is *before* Listen 80..
  
-       openssl req -new -key www.example.com.key -out www.example.com.csr
  
+ = add a VH *:443 =
-       This command will prompt for the following X.509 attributes of the certificate:
-        
-       Country Name: Use the two-letter code without punctuation for country, for example:
US or CA.
-       State or Province: Spell out the state completely; do not abbreviate the state or
province name, for example: California
-       Locality or City: The Locality field is the city or town name, for example: Berkeley.
Do not abbreviate. For example: Saint Louis, not St. Louis
-       Company: If your company or department has an &, @, or any other symbol using
the shift key in its name, you must spell out the symbol or omit it to enroll. Example: XY
& Z Corporation would be XYZ Corporation or XY and Z Corportation.
-       Organizational Unit: This field is optional; but can be used to help identify certificates
registered to an organization. The Organizational Unit (OU) field is the name of the department
or organization unit making the request. To skip the OU field, press Enter on your keyboard.
-       Common Name: The Common Name is the Host + Domain Name. It looks like "www.company.com"
or "company.com".
-       Certificates can only be used on Web servers using the Common Name specified during
enrollment. For example, a certificate for the domain "domain.com" will receive a warning
if accessing a site named "www.domain.com" or "secure.domain.com", because "www.domain.com"
and "secure.domain.com" are different from "domain.com".
-       Do not enter your email address, challenge password or an optional company name when
generating the CSR.
-       A public/private key pair has now been created. The private key (www.domain.com.key)
is stored locally on the server machine and is used for decryption. The public portion, in
the form of a Certificate Signing Request (certrequest.csr), will be for certificate enrollment
at the authority of your choice.
-       To copy and paste the information into the enrollment form, open the file in a text
editor such as Notepad or Vi and save it as a .txt file. Do not use Microsoft Word as it may
insert extra hidden characters that will alter the contents of the CSR.
-        
-       Once the CSR has been created, proceed to your certificate authority and purchase
your new certificate.
  
-    3. Install and configure mod_ssl:
+ elaborate on the option of SNI.
  
-       Install the apache httpd mod_ssl module using your Linux's distribution preferred
method 
  
-       vi /path/to/ssl.conf
+ = add cert-related directives =
  
+ These are two. Not 3409.
-       Move your key and crt files to:
-       /secure/location/ssl.key
-       /secure/location/ssl.crt
  
-       You can use the follow sample configuration file to add a SSL vhost. See http://wiki.apache.org/httpd/DistrosDefaultLayout
for more details on where linux distributions place their config files.
  
+ = passphrase stuff =
-       Configuration file:
-       #
-       # This is the Apache server configuration file providing SSL support.
-       # It contains the configuration directives to instruct the server how to
-       # serve pages over an https connection. For detailing information about these
-       # directives see <URL:http://httpd.apache.org/docs-2.0/mod/mod_ssl.html>
-       #
-       # 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.
-       #
-       LoadModule ssl_module modules/mod_ssl.so
-       #   Until documentation is completed, please check http://www.modssl.org/
-       #   for additional config examples and module docmentation.  Directives
-       #   and features of mod_ssl are largely unchanged from the mod_ssl project
-       #   for Apache 1.3.
-       #
-       # When we also provide SSL we have to listen to the
-       # standard HTTP port (see above) and to the HTTPS port
-       #

-       #   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.
-       SetEnvIf User-Agent ".*MSIE.*" \
-                nokeepalive ssl-unclean-shutdown \
-                downgrade-1.0 force-response-1.0
-       #   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.
-       CustomLog logs/ssl_request_log \
-                 "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

-       Apache/2.2.x mod_ssl/2.2.x (Pass Phrase Dialog)
-       Some of your private key files are encrypted for security reasons.
-       In order to read them you have to provide the pass phrases.

- Explanation troubleshooting basics and expectations.
- 
-    1. Test your new SSL connection:
- 
-       Visit: https://www.example.com
- 
-    2. Make sure apache httpd is started and that port 443 is open. Also, make sure you have
configured apache httpd correctly apart from the SSL configuration.
