“REmatch, a complete binary diffing framework that is free and strives to be open source and community driven.
REmatch, a simple binary diffing utility that just works. At least, we hope it will be. Rematch is still a work in progress and is not fully functional at the moment. We’re currently working on bringing up basic functionality. Check us out again soon or watch for updates! It is intended to be used by reverse engineers by revealing and identifying previously reverse engineered similar functions and migrating documentation and annotations to current IDB. It does that by locally collecting data about functions in your IDB and uploading that information to a web service (which you’re supposed to set up as well). Upon request, the web service can match your functions against all (or part) of previously uploaded functions and provide matches. A secondary goal of this (which is not currently pursued) is to allow synchronization between multiple reverse engineers working on the same file. The goal of REmatch is to act as a maintained, extendable, open source tool for advanced assembly function-level binary comparison and matching. Rematch will be a completely open source and free (as in speech) community-driven tool. We support buttom-up organizational methods and desire Rematch to be heavily influenced by it’s users (both in decision making and development).[…]”
