Packages

Here are guides to install or integrate LIEF:

Getting started

Python

import lief

# ELF
binary = lief.parse("/usr/bin/ls")
for section in binary.sections:
    print(section.name, section.virtual_address)

# PE
binary = lief.parse("C:\\Windows\\explorer.exe")

if rheader := pe.rich_header:
    print(rheader.key)

# Mach-O
binary = lief.parse("/usr/bin/ls")
for fixup in binary.dyld_chained_fixups:
    print(fixup)

Rust

use lief::Binary;
use lief::pe::debug::Entries::CodeViewPDB;

if let Some(Binary::PE(pe)) = Binary::parse(path.as_str()) {
    for entry in pe.debug() {
        if let CodeViewPDB(pdb_view) = entry {
            println!("{}", pdb_view.filename());
        }
    }
}

C++

#include <LIEF/LIEF.hpp>

int main(int argc, char** argv) {
  // ELF
  if (std::unique_ptr<const LIEF::ELF::Binary> elf = LIEF::ELF::Parser::parse("/bin/ls")) {
    for (const LIEF::ELF::Section& section : elf->sections()) {
      std::cout << section->name() << ' ' << section->virtual_address() << '\n';
    }
  }

  // PE
  if (std::unique_ptr<const LIEF::PE::Binary> pe = LIEF::PE::Parser::parse("C:\\Windows\\explorer.exe")) {
    if (const LIEF::PE::RichHeader* rheader : pe->rich_header()) {
      std::cout << rheader->key() << '\n';
    }
  }

  // Mach-O
  if (std::unique_ptr<LIEF::MachO::FatBinary> macho = LIEF::MachO::Parser::parse("/bin/ls")) {
    for (const LIEF::MachO::DyldChainedFixups& fixup : macho->dyld_chained_fixups()) {
      std::cout << fixup << '\n';
    }
  }

  return 0;
}

C (Limited API)

#include <LIEF/LIEF.h>

int main(int argc, char** argv) {
  Elf_Binary_t* elf = elf_parse("/usr/bin/ls");

  Elf_Section_t** sections = elf->sections;

  for (size_t i = 0; sections[i] != NULL; ++i) {
    printf("%s\n", sections[i]->name);
  }

  elf_binary_destroy(elf);
  return 0;
}
