Description: asmDiff is an binary assembly search, diff and disassembly tool. It supports Windows PE (exe/dll) and Linux ELF binary format compiled for x86 and x68_64 architectures. It is particular useful when searching for asm functions, instructions or memory pointers in a patched, updated or otherwise modified binary.

- Single search mode, if one needs to test one or several addresses by hand.
- Supports batch mode updates. A header file (containing lots of hardcoded pointers) and two binary files (old, new) is given as input. asmDIFF can then output a "new" header file for the updated binary. Extremely helpful on reverse engineering projects that get updated.
- Can find similar functions in different programs. But this can behave very fuzzy. It was tested on related programs where it workes with moderate success.
- Full diff mode. It prints out the entry points of "new", "modified" and "removed" functions.

Currently a full featured WebBased version is available. asmDIFF is also included in mmBBQ ( version 3.X and upwards.
