DEXrs is an exploratory project in Rust aimed at developing a decompiler for Android executable files (DEX files).
- A (blazingly fast) DEX file parser using lazy parsing
- A simple disassembler for Dalvik byte code
- A simplistic Smali decompiler
- Basic Java decompiler
- Bytecode modification and DEX rebuild
Install DEXrs using Cargo:
cargo install --git https://github.com/MatrixEditor/dexrs dexrsHere’s a quick example of how to disassemble a DEX file:
let mut f = File::open("classes.dex").expect("file not found");
// parse DEX input and verify its contents
let mut dex = Dex::read(&mut f, true)?;
let class = dex.get_class_def(0)?;
if let Some(method) = class.get_direct_method(0) {
for insn in method.disasm(&mut dex)? {
println!(" {:#06x}: {:?}", insn.range.start, insn);
}
}use dexrs::smali::SmaliWrite;
let mut f = File::open("classes.dex").expect("file not found");
let mut dex = Dex::read(&mut f, true)?;
let class = dex.get_class_def(0)?;
let mut stdout = std::io::stdout();
stdout.write_class(&class, &mut dex)?;This project is licensed under the MIT license
