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++, Python, Rust and C
First, make sure to have an updated version of setuptools:
pip install setuptools --upgradeTo install the latest version (release):
pip install liefTo install nightly build:
pip install [--user] --index-url https://lief.s3-website.fr-par.scw.cloud/latest lief==0.16.0.dev0- Nightly:
- v0.15.1: https://github.com/lief-project/LIEF/releases/tag/0.15.1
Here are guides to install or integrate LIEF:
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)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());
}
}

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()) {

}
}
// 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()) {

}
}
return 0;
