Quick, simple implementation of Error Level Analysis
#!/usr/bin/env python
# This is a really simple implementation of ELA as described in
# http://blackhat.com/presentations/bh-dc-08/Krawetz/Whitepaper/bh-dc-08-krawetz-WP.pdf
# You shouldn't actually use it, or at least read the paper carefully
# and implement more of the techniques before drawing any conclusions.

Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

tommcfarlin / meta-data-serialization.php
Last active November 4, 2022 00:28
An example function used to demonstrate how meta data is typically saved in a WordPress theme or plugin. The gist is made public so that developers can contribute to the standard security boilerplate functionality in order to simplify, reduce, and improve our serialization functions.
<?php
/**
* An example function used to demonstrate how to use the `user_can_save` function
* that provides boilerplate security checks when saving custom post meta data.
*
* The ultimate goal is provide a simple helper function to be used in themes and
* plugins without the need to use a set of complex conditionals and constants.
*
* Instead, the aim is to have a simplified function that's easy to read and that uses
* WordPress APIs.
