A realtime assembler/disassembler (formerly known as disasm.ninja)

disasm.pro

Formerly known as disasm.ninja, It's a multi-architecture realtime assembler/disassembler with line-to-line correlation. A live version is currently up at https://disasm.pro/

What and Why

It is basically a nice frontend of my keystone fork (for line-to-line assembling) and capstone. I don't normally do frontend development but I wanted something for quickly analyzing tiny snippets of code (mostly during CTFs) and shellcoding, which led to this.

I know there are other online assemblers/disassemblers out there, but none of them fit my exact needs.

Support

It currently supports 5 architectures:

• x86/64
• ARMv8
• MIPS
• Sparc
• PowerPC

Most typical assembler directives are also supported. Macros are not fully supported.

Installation

To Install and run it locally:

• Git clone with submodules

git clone https://github.com/ret2got/disasm.pro.git --recursive
cd disasm.pro

• Build and Install the keystone fork (It's a submodule)

cd keystone
mkdir build; cd build
../make-share.sh; sudo make install

• Install the Python3 bindings

cd bindings/python
sudo make install3

• Install Python dependencies

pip3 install -r requirements.txt

Now you can run it by executing the ninja.py

python3 ninja.py
