Unofficial Rust SDK for VMProtect

vmprotect

WIP VMProtect SDK for rust

Basic VMProtect features

protected! macro for code

Syntax:

use vmprotect::protected;

protected!("NAME"; TYPE [KEY]; { /*CODE*/ })

• NAME: Which name will be displayed in VMProtect GUI
• TYPE: Protection type (mutate/virtualize/ultra per VMProtect docs)
• [KEY]: For virtualize/ultra only, require license activation to get this function to work
• CODE: Your code goes here

Protected code block is works like any other rust block, i.e:

use vmprotect::protected;

// Before protection
let a = {2+3};
// After protection
let a = protected!("Addiction"; virtualize false; { 2 + 3 });

Example:

#![feature(test)] // For black_box support

use vmprotect::protected;
use std::hint::black_box;

fn main() {
    // Blackboxes here is to not inline the math
    let a = black_box(2);
    let b = black_box(3);
    // Also you can blackbox values by yourself:
    // unsafe { asm!("" : : "r"(&a), "r"(&b)) }
    println!("{} + {} = {}", a, b, protected!("Adding"; ultra false; {
        a + b
    }));
}

protected! macro for texts

Syntax:

use vmprotect::protected;

protected!(TYPE "TEXT")

• TYPE: Text type, possible values: A (for normal c strings)/W (for uint16_t c strings (Used i.e in windows))
• TEXT: Your text, should be supported by your selected text type

This macro returns string, which can be transformed to normal one. This string is freed when dropped, implementations is located at vmprotect::strings::{encrypted_a::EncryptedStringA, encrypted_w::EncryptedStringW}

use vmprotect::protected;

// Before protection
let a = "Hello, world!";
// After protection
let a = protected!(A; "Hello, world!");
// Also for wide-strings:
let a = protected!(W; "Привет, мир!");

Example:

#![feature(type_ascription)] // For `.into(): T` syntax support

use vmprotect::protected;

fn main() {
    println!("Hello, {:?}!", protected!(A; "%Username%").into(): String);
}

Licensing

TODO Section, see docs for now

HWID

Example:

println!("Your hwid is \"{}\"", vmprotect::licensing::get_hwid().to_str().unwrap());

Known problems

MacOS: Not enough space for the new segment in the file header

Can be fixed by adding -C link-arg=-Wl,-headerpad,0x500 to rustc args

For cargo:

export RUSTFLAGS="-C link-arg=-Wl,-headerpad,0x500"
