Powerful Disassembler Library For x86/AMD64
Welcome to the diStorm3 binary stream disassembler library project.
diStorm3 is really a decomposer, which means it takes an instruction and returns a binary structure which describes it rather than static text, which is great for advanced binary code analysis.
diStorm3 is super lightweight (~45KB), ultra fast and easy to use (a single API), licensed under BSD!
For a light hooking library see the https://github.com/gdabah/distormx project.
"We benchmarked five popular open-source disassembly libraries and chose diStorm3, which had the best performance (and furthermore, has complete 64-bit support).", July 2014, Quoting David Williams-King in his Thesis about Binary Shuffling.
Installing diStorm3 - 'python -m pip install distorm3'
RTFM, the wiki has plenty of info.
