# cryptify
`cryptify` is a procedural macro crate for compile-time rust obfuscation. It provides the user with string encryption and compile-time determined flow obfuscation and random variables which survive compile-time optimization.
[rust-obfuscator](https://github.com/dronavallipranav/rust-obfuscator) - Check out this auto obfuscator tool for easier usage and integration
## Features
- **String Obfuscation**: Automatically encrypts string literals in your code at compile time, making them harder to read and understand.
- **Flow Obfuscation**: Introduces dummy loops and random variables into control flows, enhancing the overall obfuscation of the logic.
# Usage
## Bring macro into scope
```rs
use cryptify;
fn main(){
let decrypted = cryptify::encrypt_string!("Hello, World!");
println!(decrypted);
println!("{}", cryptify::encrypt_string!("formatted!"));
}
```
Set the **CRYPTIFY_KEY** environment variable for custom encryption otherwise it defaults to defined fixed key
## Output
```
Hello World!
formatted!
```
## Example of expanded Flow_Stmt!
```rs
{
{
let _is_dummy_145 = true;
let mut _dummy_counter = std::hint::black_box(4i32 as i32);
let _dummy_increment = std::hint::black_box(1i32 as i32);
let _dummy_upper_bound = std::hint::black_box(53i32 as i32);
loop {
if std::hint::black_box(_dummy_counter)
> std::hint::black_box(_dummy_upper_bound)
{
break;
}
_dummy_counter = std::hint::black_box(
std::hint::black_box(_dummy_counter)
+ std::hint::black_box(_dummy_increment),
);
}
};
match (&1, &1) {
(left_val, right_val) => {
if !(*left_val == *right_val) {
let kind = ::core::panicking::AssertKind::Eq;
::core::panicking::assert_failed(
kind,
&*left_val,
&*right_val,
::core::option::Option::None,
);
}
}
};
}
