A very simple, yet powerful, Flask captcha extension
Project description
# Flask-Captcha
Python Simple Captcha is an extremely simple, yet highly customizable flask extension to use
## Features
Very simple to setup and deploy, yet very configurable
Can use custom challenges (e.g. random chars, simple maths, dictionary word, …)
Custom generators, noise and filter functions alter the look of the generated image
Supports text-to-speech audio output of the challenge text, for improved accessibility
## Requirements
Python 3.3+
Flask
A recent version of the Python Imaging Library (Pillow 2.2+) compiled with FreeType support
Flite is required for text-to-speech (audio) output, but not mandatory
## Troubleshooting
If the captcha does not render, try opening the img url link directly. If you get this error
“Python: The _imagingft C module is not installed”
You need to recompile Pillow with libfreetype6 support. To do this
$ sudo apt-get install libfreetype6-dev
$ pip uninstall pillow
$ pip install pillow
## Development and releases
Developers with release credentials can upload a new version to Pypi using the following two commands:
$ python setup.py sdist upload $ python setup.py bdist_egg upload
- To create a new release, you need to:
update the VERSION variable in flask_captcha/__init__.py
updated the version in the setup.py script
create a git tag for the release
