Project description

Apache Password Changer

A web Interface for users change their own passwords on a htpasswd file.


Apache Password Changer is a simple Flask project that provides resources
to users change their own passwords in a secure way.(usually this operation
needs to be done by an administrator with direct access to the server).


* Apache and gunicorn installed or similar setup.
* The htpasswd file must be exist.
* The site must be served through SSL (Security Reasons).

For more information, take a look at:

Other ways to deploy are available as well (uwsgi, passenger and others) at the
same page.


1. Install the project through PIP (a virtualenv is highly recommended):

pip install htpwd

Configuration - Apache + Gunicorn

For quick purposes, the samples included in the deploy directory can help a fast
deploy in an Apache WebServer. If you choose to do so, the following guidelines
can be applied:

* Create a specific user and group to run the project;
* Copy the '' and '' to the home directory of the user
created and change the environment variables contained in '' as per

* HTPASSWD_FILE: The location of htpasswd file (eg: /data/app.htpasswd)

* SECRET_KEY: Secret key that will be used within session and csrf_token.
eg: echo "SOMESTRINGHERE" | md5sum

* REGEXP: Some verification regexp, that will be used to verify the
user name field. Must be provided. If False, it will be defined as [A-z0-9_.]+,
all possible matches.

eg: ^\d{11}@ENTERPRISE$ will match Brazilian CPF appended with the

* TARGET_PAGE: The link for a page which the user can access with the new
password. eg:

If you need a diferente port for the gunicorn process, change it in

Bellow a full example of the changes needed:

Base subdomain:
User: htpwd
Group: htpwd
Regexp: \d{11}
#Define all needed environment variables

# And export then

# Activate the virtualenv and then, start gunicorn
source /data/backstage3.3/bin/activate
gunicorn -D -c htpwd.htpwd:app
import multiprocessing

#The internal port, must be the same on the Apache Proxy configuration
bind = ""

# The best default configuration ever
workers = multiprocessing.cpu_count() * 2 + 1

#A virtualhost with SSL and mod_proxy activated.
<VirtualHost *:443>
SSLEngine on
SSLCertificateFile /data/your.cert
SSLCertificateKeyFIle /data/your.key
ErrorLog /var/log/httpd/htpwd_errors.log
CustomLog /var/log/httpd/htpwd_custom.log common
ProxyPreserveHost On

<Location "/">
RequestHeader set X-FORWARDED-PROTOCOL ssl
RequestHeader set X-FORWARDED-SSL on


To develop using the package, you must install the requirements as noted, define
the environment variables and then, start the development server through the command:

runserver -d -r


TO translate the pages included in the project, you must first add a new language
in the LANGUAGE DICT using the ISO language notation(info available at, like the example bellow:

'en': 'English',
'pt_BR': 'Português do Brasil',
'es': 'Espanish'

As noted, the espanish language was added into the current languages suuport.

By default, the project supports English (Native in the whole project) and
Brazilian Portuguese. After add a new language, you need to init the directory
with include the gettext .po file designed for the target language (at the top
of directory):

pybabel extract -F babel.cfg -o messages.pot .
pybabel init -i messages.pot -d translations -l <ISO_LANGUAGE>

After that, a new directory will be created insided the translations directory,
within and LC_MESSAGES directory and a messages.po file; this last file, contains
all strings that will be translated.

For easy use, we recommend the translation using the poeditor or 'Loco' available
at which allow users to translate and get .po and .mo files
directly from browser.
