The purpose of this project is to provide a cross platform library which can parse, modify and abstract
MachO and Android formats.
- Parser: LIEF can parse
VDEX. Moreover it 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
The global architecture looks like this:
In the architecture, each format has its own namespace, parser and builder.
The parser takes a binary, library… as input and decomposes in LIEF object.
For instance, the
ELF format has segments, so
ELF::Parser will parse segments to create
ELF::Segment. In the
ELF::Binary class we will have a list of
ELF::Segment which can be modified (change type, size, content…). Then the
ELF::Builder will transform
ELF::Binary into a valid executable.
This process can be summed up in the following figure:
