xorstr-rs

Overview

xorstr-rs is a Rust port of the xorstr library, implemented in C++ by JustasMasiulis. This library provides a way to obfuscate strings in your Rust binaries at compile time.

Usage / Example

mod xorstr;

fn main() {
    let xorstr = xorstr!("hello world from earth");
    println!("{}", xorstr.as_str().unwrap());
}
