# About

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, OAT, DEX, VDEX, ART 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

Here are guides to install or integrate LIEF:

  * [Python](https://lief.quarkslab.com/doc/latest/installation.html#python)
  * [VisualStudio](https://lief.quarkslab.com/doc/latest/installation.html#visual-studio-integration)
  * [XCode](https://lief.quarkslab.com/doc/latest/installation.html#xcode-integration)
  * [CMake](https://lief.quarkslab.com/doc/latest/installation.html#cmake-integration)

## Getting started

### Python

```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++

```cpp
#include <LIEF/LIEF.hpp>

int main(int argc, char** argv) {
  // ELF
  try {
    std::unique_ptr<LIEF::ELF::Binary> elf = LIEF::ELF::Parser::parse("/bin/ls");
    std::cout << *elf << std::endl;
  } catch (const LIEF::exception& err) {
    std::cerr << err.what() << std::endl;
  }

  // PE
  try {
    std::unique_ptr<LIEF::PE::Binary> pe = LIEF::PE::Parser::parse("C:\\Windows\\explorer.exe");
    std::cout << *pe << std::endl;
  } catch (const LIEF::exception& err) {
    std::cerr << err.what() << std::endl;
  }

  // Mach-O
  try {
    std::unique_ptr<LIEF::MachO::FatBinary> macho = LIEF::MachO::Parser::parse("/bin/ls");
    std::cout << *macho << std::endl;
  } catch (const LIEF::exception& err) {
    std::cerr << err.what() << std::endl;
  }

  return 0;
}

```

### C (Limited API)

```cpp
#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;
}
```
