Important.png Note:
For v10 we have created a new update version of PHPKi called PHPKi-ng with fixes and higher security defaults. If you used the previous version you will need to create a new CA and certificates. We have imported the original version to contribs if you really need to use it, but it is not recommended, and will not be generally released.

Contrib 10:
The latest version of phpki-ng is available in the SME repository, click on the version number(s) for more information.

Please follow the installation instructions below. The installation instructions will satisfy all dependencies and the latest versions of the above 2 RPMs will be installed automatically.


PHPki is an Open Source Web application for managing a multi-agency PKI for HIPAA compliance. With it, you may create and centrally manage X.509 certificates for use with S/MIME enabled e-mail clients, SSL servers, and VPN applications. PHPki is now used to manage certificates with the latest release of the SME Server OpenVPN Bridge contrib.

You can see a demo installation here.


Warning.png Warning:
This version of PHPki is a slightly modified version, so it can be used with certificates generated with previous release of smeserver-openvpn-bridge, plus some others minor modifications.

Starting phpki-ng-0.84, default_md has been upgraded to sha512 (previous was sha1). You can keep your existing CA working, but we strongly advise you to upgrade to a new instance, as the weak sha1 hash is a security issue.


Warning.png Warning:
If openvpn is not detected PHPKi cannot generate a TA Key and it should advise you during install. To generate a TA Key once you have openvpn installed do this (assuming this is the correct directory)
openvpn --genkey --secret /opt/phpki/phpki-store/CA/private/takey.pem 
chown phpki:phpki /opt/phpki/phpki-store/CA/private/takey.pem

  • install the rpms
yum --enablerepo=smecontribs install smeserver-phpki-ng

go to the server-manager to the manage certificate menu and start creating your CA certificate

Warning click only once and wait for the page to update it can be very long to create the 4096 certificate...

you have to enable the epel repository

  • install the rpms
yum --enablerepo=smecontribs,epel install smeserver-phpki
  • and start/restart needed services:
expand-template /etc/httpd/conf/httpd.conf
expand-template /etc/httpd/pki-conf/httpd.conf
sv t /service/httpd-e-smith
sv u /service/httpd-pki
  • alternatively issue the following :
signal-event post-upgrade; signal-event reboot

on update you can issue

expand-template /etc/httpd/conf/httpd.conf
expand-template /etc/httpd/pki-conf/httpd.conf
sv t /service/httpd-e-smith
sv t /service/httpd-pki

For sme8

  • install the rpms
yum --enablerepo=smecontribs install smeserver-phpki
  • and start/restart needed services:
expand-template /etc/httpd/conf/httpd.conf
expand-template /etc/httpd/pki-conf/httpd.conf
sv t /service/httpd-e-smith
sv u /service/httpd-pki
  • alternatively issue the following :
signal-event post-upgrade; signal-event reboot

Configure your new PKI

Go in the server-manager, you'll find a new "Manage Certificates" menu (or you can use the URL https://server.domain.tld/phpki/ca) Here you have to enter the following informations:

    • Organisation
    • Department
    • Common Name of the Master CA
    • E-mail (technical contact)
    • City
    • State
    • Country Code
    • Password (to protect the private key of the Master CA)
    • Validity of the CA
    • Keys size
    • URL of your PKI (https://my.domain.tld/phpki)

These two screenshots illustrate the first (and the most important) part of this configuration page:

First part of the initiale configuration page (above)
First part of the initiale configuration page (low)

The second part is like this:

Second part of the initiale configuration page

The default settings should be OK for most installations. You may just want to change the "Help Document Contact Info" part.

Once you have submitted this form (which can take several minutes, be patient, as generating dh parameters can take a long time), you should have something like this:

Second part of the initiale configuration page

Now you'll be able to start using PHPki. It's quite easy to use.

The administrative interface is available on the server-manager or directly https://my.domain.tld/phpki/ca

There's also a public interface, available only from the local networks, but without password at https://my.domain.tld/phpki. Here, users can download the Master CA certificate, the CRL, or search for certificates of other users (public part only of course).

Important.png Note:
If you just installed the OpenVPN_Bridge contrib and are installing PHPki as suggested by the wiki page, or you just want to use PHPki without OpenVPN_Bridge contrib, then you are done here, and you don't have to migrate any certificates

Important.png Note:
starting phpki-ng-0.84-14 new URL are available to access your CRL and request for certificate status

Add another admin

if you happen to need to delegate certificate generation, you can use user-panel to add access to the panel, but you will also need to add the user manually to phpki config

edit /opt/phpki/phpki-store/config/config.php

#$PHPki_admins = Array(md5('admin'));
$PHPki_admins = Array(md5('admin'),md5('user2'));


To uninstall the contrib from your server, just run the following commands:

yum remove smeserver-phpki-ng phpki-ng
expand-template /etc/httpd/conf/httpd.conf
systemctl restart /service/httpd-e-smith

Important.png Note:
As with many other rpms, removing phpki won't remove everything from your server. Especially certificates will be kept, and some php files. PHPKi-ng will attempt to backup any old certificates.

Certificates and PKI configuration are stored in /opt/phpki/phpki-store, php files are in /opt/phpki/html

Warning.png Warning:
To start from scratch after uninstallation you need to get rid of the html and pkpki-store directories before reinstalling.

The files in phpki-store can be very important, so my recommendation is to let them remain here. If you really want to remove them, just backup them before:

cd /opt/phpki
tar cvzf ~/phpki-backup.tar.gz ./

Now you can remove the entire /opt/phpki directory

rm /opt/phpki/{html,phpki-store} -rf


before phpki-ng 0.84-14

If you have removed the contrib, and want to re-install it keeping your previous CA (assuming you restored /opt/phpki), you'll need to follow these steps after you have installed the rpms:

cd /opt/phpki/html/
rm -f index.php 
rm -f setup.php
ln -s main.php index.php
cat config.php.rpmsave > config.php
cd ca
rm -f index.php
ln -s main.php index.php
cd /opt/phpki/
chown phpki:phpki -R phpki-store 
chown root:phpki -R html/config.php
