flash-lso

A parser/encoder for Adobe Local Shared Object (LSO) file format (.sol), AMF0 and AFM3 in 100% safe rust.

Features:

• Parsing and encoding fully supported
• Heavily tested and fuzzed
• Circular references fully supported
• Support for externalizable types (flash.utils.IExternalizable)
• Support for Adobe flex types

Example

use std::fs::File;
use std::io::Read;
use flash_lso::read::Reader;
fn main() {
    let mut x = File::open(path).expect("Couldn't open file");
    let mut data = Vec::new();
    let _ = x.read_to_end(&mut data).expect("Unable to read file");
    let d = Reader::default().parse_full(&data).expect("Failed to parse lso file");
    println!("{:#?}", d);
}

Development / Testing

To aid with development, there is a sub-project: reader, which can parse either a single file or all files in a directory and will report on which files succeeded and failed to parse

In future this will be used to verify and compare the output with the official implementation

Fuzzing

This project makes use of cargo-fuzz to ensure correct handling of invalid data

cargo fuzz run --release fuzz_amf3_body
