Requests - Python HTTP Requests for Humans

  •    Python

Requests allows you to send organic, grass-fed HTTP/1.1 requests, without the need for manual labor. There's no need to manually add query strings to your URLs, or to form-encode your POST data. Keep-alive and HTTP connection pooling are 100% automatic, thanks to urllib3. Requests is one of the most downloaded Python packages of all time, pulling in over 11,000,000 downloads every month.

mcsema - Framework for lifting x86, amd64, and aarch64 program binaries to LLVM bitcode

  •    C++

McSema is an executable lifter. It translates ("lifts") executable binaries from native machine code to LLVM bitcode. LLVM bitcode is an intermediate representation form of a program that was originally created for the retargetable LLVM compiler, but which is also very useful for performing program analysis methods that would not be possible to perform on an executable binary directly. McSema enables analysts to find and retroactively harden binary programs against security bugs, independently validate vendor source code, and generate application tests with high code coverage. McSema isn’t just for static analysis. The lifted LLVM bitcode can also be fuzzed with libFuzzer, an LLVM-based instrumented fuzzer that would otherwise require the target source code. The lifted bitcode can even be compiled back into a runnable program! This is a procedure known as static binary rewriting, binary translation, or binary recompilation.

echojs - an ahead of time compiler and runtime for ES6

  •    Javascript

The environment variable LLVM_SUFFIX can be set and its value will be appended to the names of all llvm executables (e.g. llvm-config-3.6 instead of llvm-config.) The default is -3.6. Change this if you have a different build of llvm you want to use. Homebrew installs llvm 3.6 executables without the suffix, thus export LLVM_SUFFIX=. As for MIN_OSX_VERSION: homebrew's formula for llvm (3.4, at least. haven't verified with 3.6) doesn't specify a -mmacosx-version-min= flag, so it builds to whatever you have on your machine. Node.js's gyp support in node-gyp, however, does put a -mmacosx-version-min=10.5 flag. A mismatch here causes the node-llvm binding to allocate llvm types using incorrect size calculations, and causes all manner of memory corruption. If you're either running 10.5 or 10.9, you can leave the variable unset. Otherwise, set it to the version of OSX you're running. Hopefully some discussion with the homebrew folks will get this fixed upstream.

kaleidoscope - Haskell LLVM JIT Compiler Tutorial

emscripten - Emscripten: An LLVM-to-JavaScript Compiler

  •    C

Emscripten is an LLVM-to-JavaScript compiler. It takes LLVM bitcode - which can be generated from C/C++, using llvm-gcc (DragonEgg) or clang, or any other language that can be converted into LLVM - and compiles that into JavaScript, which can be run on the web (or anywhere else JavaScript can run). Emscripten is available under 2 licenses, the MIT license and the University of Illinois/NCSA Open Source License.

llvm-clang-samples - Examples of using the LLVM and Clang compilation libraries and tools

  •    C++

A collection of samples for using LLVM and Clang as libraries. LLVM & Clang evolve rapidly and the C++ API is not stable. This means that code that links against LLVM & Clang as libraries in version X may very well not compile or work in version X+1.

SPIRV-LLVM - LLVM framework with SPIR-V support

  •    C++

The khronos/spirv-3.6.1 branch of this repository contains source code for the LLVM/SPIR-V Bi-Directional Translator, a library for translating between LLVM and SPIR-V. The LLVM/SPIR-V Bi-Directional Translator is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt.

WAVM - WebAssembly Virtual Machine

  •    WebAssembly

This is a standalone VM for WebAssembly. It can load both the standard binary format, and the text format defined by the WebAssembly reference interpreter. For the text format, it can load both the standard stack machine syntax and the old-fashioned AST syntax used by the reference interpreter, and all of the testing commands. To build it, you'll need CMake and LLVM 6.0. If CMake can't find your LLVM directory, you can manually give it the location in the LLVM_DIR CMake configuration variable. Note that on Windows, you must compile LLVM from source, and manually point the LLVM_DIR configuration variable at <LLVM build directory>\lib\cmake\llvm.

decomp - Components of a decompilation pipeline.

  •    Go

The aim of this project is to implement a decompilation pipeline composed of independent components interacting through well-defined interfaces, as further described in the design documents of the project. From a high-level perspective, the components of the decompilation pipeline are conceptually grouped into three modules. Firstly, the front-end translates a source language (e.g. x86 assembly) into LLVM IR; a platform-independent low-level intermediate representation. Secondly, the middle-end structures the LLVM IR by identifying high-level control flow primitives (e.g. pre-test loops, 2-way conditionals). Lastly, the back-end translates the structured LLVM IR into a high-level target programming language (e.g. Go).

fcd - An optimizing decompiler

  •    C++

Fcd is an LLVM-based native program optimizing decompiler, released under an LLVM-style license. It started as a bachelor's degree senior project and carries forward its initial development philosophy of getting results fast. As such, it was architectured to have low coupling between distinct decompilation phases and to be highly hackable. Fcd uses a unique technique to reliably translate machine code to LLVM IR. Currently, it only supports x86_64. Disassembly uses Capstone. It implements pattern-independent structuring to provide a goto-free output.

Hikari - LLVM Obfuscator


English Documentation Hikari(Light in Japanese, name stolen from the Nintendo Switch game Xenoblade Chronicles 2) is my hackathon-ishtoy project for the 2017 Christmas to kill time.It's already stable enough to use in production environment. However, as initially planned, Hikari has been ported to LLVM 6.0 release version and no longer being actively maintained due to the time and effort it takes. You can find the history of its development at developer branch. Further enhancements include more features like Code-Intergrity Checking and a full anti-hook implementation. These are not open-source and will probably be released as a commercial product. If you know me close enough we can discuss the license model and pricing issue because I might not be able to provide real-time bug fix and stuff. Any undiscovered potential bugs affecting the obfuscated binary are fixed during obfuscation so you get a workable binary.
