Flask-Captcha 0.1.8

A very simple, yet powerful, Flask captcha extension

# 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
