Certidude is mainly designed for VPN gateway operators to make VPN adoption usage
as simple as possible.
Certidude is mainly designed for VPN gateway operators to make
desktop/laptop VPN setup as easy as possible.
User certificate management eg. for HTTPS is also made reasonably simple.
For a full-blown CA you might want to take a look at
`EJBCA <http://www.ejbca.org/features.html>`_ or
`OpenCA <https://pki.openca.org/>`_.

Features
--------
Common:
* Standard request, sign, revoke workflow via web interface.
* Colored command-line interface, check out ``certidude list``.
* OpenVPN integration, check out ``certidude setup openvpn server`` and ``certidude setup openvpn client``.
* strongSwan integration, check out ``certidude setup strongswan server`` and ``certidude setup strongswan client``.
* Kerberos and basic auth based web interface authentication.
* PAM and Active Directory compliant authentication backends: Kerberos single sign-on, LDAP simple bind.
* POSIX groups and Active Directory (LDAP) group membership based authorization.
* Command-line interface, check out ``certidude list``.
* Privilege isolation, separate signer process is spawned per private key isolating
private key use from the the web interface.
* Certificate numbering obfuscation, certificate serial numbers are intentionally
randomized to avoid leaking information about business practices.
* Server-side events support via for example nginx-push-stream-module.
* Kerberos based web interface authentication.
* File based whitelist authorization, easy to integrate with LDAP as shown below.
* Certificate serial numbers are intentionally randomized to avoid leaking information about business practices.
* Server-side events support via `nchan <https://nchan.slact.net/>`_.
* E-mail notifications about pending, signed and revoked certificates.
Virtual private networking:
Coming soon
-----------
* OpenVPN integration, check out ``certidude setup openvpn server`` and ``certidude setup openvpn client``.
* strongSwan integration, check out ``certidude setup strongswan server`` and ``certidude setup strongswan client``.
* NetworkManager integration, check out ``certidude setup openvpn networkmanager`` and ``certidude setup strongswan networkmanager``.
* Refactor mailing subsystem and server-side events to use hooks.
* Notifications via e-mail.
HTTPS:
* P12 bundle generation for web browsers, seems to work well with Android
* HTTPS server setup with client verification, check out ``certidude setup nginx``

.. code:: bash
[authorization]
backend = ldap
ldap gssapi credential cache = /run/certidude/krb5cc

ldap admin filter = (&(objectclass=user)(objectclass=person)(memberOf=cn=Domain Admins,cn=Users,dc=example,dc=com)(samaccountname=%s))
admin_users=alice bob john kate
Or alternatively specify file path:
.. code:: bash
admin_users=/run/certidude/user.whitelist
Use following shell snippets eg in ``/etc/cron.hourly/update-certidude-user-whitelist``
to generate user whitelist via LDAP:
.. code:: bash
ldapsearch -H ldap://dc1.example.com -s sub -x -LLL \
-D 'cn=certidude,cn=Users,dc=example,dc=com' \
-w 'certidudepass' \

> /run/certidude/user.whitelist
Set permissions:
.. code:: bash
chmod 700 /etc/cron.hourly/update-certidude-user-whitelist
User filter here specified which users can log in to Certidude web interface
at all eg. for generating user certificates for HTTPS.
Admin filter specifies which users are allowed to sign and revoke certificates.
Adjust admin filter according to your setup.
Also make sure there is cron.hourly job for creating GSSAPI credential cache -
that's necessary for querying LDAP using Certidude machine's credentials.
