vmprotect

WIP VMProtect SDK for rust

Basic VMProtect features

protected attribute

You need to add this script to vmprotect project for this attribute

Syntax:

```rust

[protected(TYPE[, lock])]

fn some_fn() { ... } ```

• TYPE: Protection type
• [, lock]: Require license to get this function to work.

Example:

```rust

[protected(virtualize)]

fn stringify(value: T) -> String { format!("{}", value) } ```

protected! macro for code

Syntax:

```rust use vmprotect::protected;

protected!(TYPE[, lock] "NAME"; { /CODE/ }) ```

• NAME: Which name will be displayed in VMProtect GUI
• TYPE: Protection type (mutate/virtualize/ultra per VMProtect docs)
• [, lock]: 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:

```rust use vmprotect::protected;

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

Example:

rust fn main() { println!("{} + {} = {}", a, b, protected!(ultra "Adding"; { a + b })); }

protected! macro for texts

Syntax:

```rust use vmprotect::protected;

protected!(TYPE "TEXT") ```

• TYPE: Text type, possible values: cstr (for normal c strings)/cwstr (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}

```rust use vmprotect::protected;

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

Example:

```rust use vmprotect::protected;

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

Licensing

TODO Section, see docs for now

HWID

Example:

rust 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:

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