elfcat - ELF visualizer. Generates HTML files from ELF binaries.

  1. How do I install and use it?

    $ cargo install elfcat $ elfcat path/to/file

  2. How does it look like?

    This is how the following small example ELF file looks like:

    http://ruslashev.github.io/elfcat/hello_world.html

    Steps to create it:

    $ cat hello_world.s global _start

    section .text _start: mov rax, 1 mov rdi, 1 mov rsi, msg mov rdx, len syscall

       mov rax, 60
   xor rdi, rdi
   syscall

    section .data msg db "Hello, world!", 0xA len equ $ - msg

    $ cat link.ld ENTRY(_start)

    SECTIONS { . = 0x10080; /* vm.mmapminaddr + p_offset of first segment */

       .text : {
       * (.text)
   }

   .data : {
       * (.data)
   }

    }

    $ nasm helloworld.s -f elf64 $ ld helloworld.o -o helloworld -n -T link.ld $ elfcat helloworld $ xdg-open hello_world.html

  3. Can I contribute?

    Of course!

  4. License?

    Zlib.

  5. When I try this on huge files, it slows down my browser!

    Sorry about that. There used to be a feature where segments and sections would be collapsed into a couple characters instead of showing full contents, but it was disabled because it:
