OWASP PureCaptcha

Use CAPTCHAs in your application without any dependencies, no required libraries and nothing to install. Just include a single small source-code file to have fully functional lightweight CAPTCHAs in your project.

Description

CAPTCHA is a feature detecting humans from computers, needed in many aspects of all web applications to prevent bots from flooding and spamming. Unfortunately all existing libraries and APIs require too much effort for a small application to be feasible and maintainable, so a lot of developers just give up on using CAPTCHAs where they are needed. This is due to the fact that generating CAPTCHAs requires a large body of code libraries to be available. It depends on image manipulation (like GD and Imagick), font rendering (Freetype and etc.) SOAP or Curl and etc. each of which are high level libraries and have a lot more dependencies. PureCapthca provides a single source code file which does the entire CAPTCHA generation and handling, because it only includes code for rendering a few alphanumeric letters from scratch, creating simple BMP files from nothing and modifying simple bitmap images.

This allows developers to easily add a single source code file to their projects and reap full CAPTCHA benefits with minimal memory and processing footprint and ZERO dependencies.

News and Events

This is where you can provide project updates, links to any events like conference presentations, Project Leader interviews, case studies on successful project implementations, and articles written about your project.


Many projects have "Frequently Asked Questions" documents or pages. However, the point of such a document is not the questions. The point of a document like this are the answers. The document contains the answers that people would otherwise find themselves giving over and over again. The idea is that rather than laboriously compose and post the same answers repeatedly, people can refer to this page with pre-prepared answers. Use this space to communicate your projects 'Frequent Answers.'

How can I participate in your project?

All you have to do is make the Project Leader's aware of your available time to contribute to the project. It is also important to let the Leader's know how you would like to contribute and pitch in to help the project meet it's goals and milestones. There are many different ways you can contribute to an OWASP Project, but communication with the leads is key.

If I am not a programmer can I participate in your project?

Yes, you can certainly participate in the project if you are not a programmer or technical. The project needs different skills and expertise and different times during its development. Currently, we are looking for researchers, writers, graphic designers, and a project administrator.

Volunteers

The success of OWASP is due to a community of enthusiasts and contributors that work to make our projects great. This is also true for the success of your project. Be sure to give credit where credit is due, no matter how small! This should be a brief list of the most amazing people involved in your project. Be sure to provide a link to a complete list of all the amazing people in your project's community as well.


The first contributors to the project were:

A project roadmap is the envisioned plan for the project. The purpose of the roadmap is to help others understand where the project is going as well as areas that volunteers may contribute. It gives the community a chance to understand the context and the vision for the goal of the project. Additionally, if a project becomes inactive, or if the project is abandoned, a roadmap can help ensure a project can be adopted and continued under new leadership. Roadmaps vary in detail from a broad outline to a fully detailed project charter. Generally speaking, projects with detailed roadmaps have tended to develop into successful projects. Some details that leaders may consider placing in the roadmap include: envisioned milestones, planned feature enhancements, essential conditions, project assumptions, development timelines, etc. You are required to have at least 4 milestones for every year the project is active.

Roadmap

Currently PHP library is available and tested. Porting to all major programming languages is the next step. Since the library is pretty small, this shouldn't be a hard task and can be done in one summer by 1 candidate.

Getting Involved

Involvement in the development and promotion is actively encouraged! You do not have to be a security expert or a programmer to contribute. Some of the ways you can help are as follows:

Coding

Localization

Are you fluent in another language? Can you help translate the text strings into that language?

Testing

Do you have a flair for finding bugs in software? We want to product a high quality product, so any help with Quality Assurance would be greatly appreciated. Let us know if you can offer your help.

Feedback

mailing list

  • What do like?
  • What don't you like?
  • What features would you like to see prioritized on the roadmap?

This page is where you should indicate what is the minimum set of functionality that is required to make this a useful product that addresses your core security concern. Defining this information helps the project leader to think about what is the critical functionality that a user needs for this project to be useful, thereby helping determine what the priorities should be on the roadmap. And it also helps reviewers who are evaluating the project to determine if the functionality sufficiently provides the critical functionality to determine if the project should be promoted to the next project category.


This page is where you need to place your legacy project template page if your project was created before October 2013. To edit this page you will need to edit your project information template. You can typically find this page by following this address and substituting your project name where it says "OWASP_Example_Project". When in doubt, ask the OWASP Projects Manager.
