LIEF - Library to Instrument Executable Formats.

The purpose of this project is to provide a cross platform library which can parse, modify and abstract ELF, PE and MachO formats.
Main features:

• Parsing: LIEF can parse ELF, PE, MachO and provides an user-friendly API to access to format internals.
• Modify: LIEF enables to modify some parts of these formats
• Abstract: Three formats have common features like sections, symbols, entry point... LIEF factors them.
• API: LIEF can be used in C, C++ and Python

  Getting started

  Python

  import lief
  # ELF
  binary = lief.parse("/usr/bin/ls")
  print(binary)
  
  # PE
  binary = lief.parse("C:\\Windows\\explorer.exe")
  print(binary)
  
  # Mach-O
  binary = lief.parse("/usr/bin/ls")
  print(binary)
  

  C++

  #include <LIEF/LIEF.hpp>
  int main(int argc, const char** argv) {
    LIEF::ELF::Binary*   elf   = LIEF::ELF::Parser::parse("/usr/bin/ls");
    LIEF::PE::Binary*    pe    = LIEF::PE::Parser::parse("C:\\Windows\\explorer.exe");
    LIEF::MachO::Binary* macho = LIEF::MachO::Parser::parse("/usr/bin/ls");
  
    std::cout << *elf   << std::endl;
    std::cout << *pe    << std::endl;
    std::cout << *macho << std::endl;
  
    delete elf;
    delete pe;
    delete macho;
  }

  C

  #include <LIEF/LIEF.h>
  int main(int argc, const char** argv) {
  
    Elf_Binary_t*    elf_binary     = elf_parse("/usr/bin/ls");
    Pe_Binary_t*     pe_binary      = pe_parse("C:\\Windows\\explorer.exe");
    Macho_Binary_t** macho_binaries = macho_parse("/usr/bin/ls");
  
    Pe_Section_t**    pe_sections    = pe_binary->sections;
    Elf_Section_t**   elf_sections   = elf_binary->sections;
    Macho_Section_t** macho_sections = macho_binaries[0]->sections;
  
    for (size_t i = 0; pe_sections[i] != NULL; ++i) {
      printf("%s\n", pe_sections[i]->name)
    }
  
    for (size_t i = 0; elf_sections[i] != NULL; ++i) {
      printf("%s\n", elf_sections[i]->name)
    }
  
    for (size_t i = 0; macho_sections[i] != NULL; ++i) {
      printf("%s\n", macho_sections[i]->name)
    }
  
    elf_binary_destroy(elf_binary);
    pe_binary_destroy(pe_binary);
    macho_binaries_destroy(macho_binaries);
  }
