str_crypter is a Rust library for XOR encryption and decryption of strings. It provides a macro to XOR encrypt strings from plaintext at compile time using a single byte key. When building in release mode, any plaintext strings encrypted with the macro sc!() will not be present in the binary. At runtime, the macro expands to decrypt the encrypted string.

use str_crypter::{decrypt_string, sc};

fn main() {
    let encrypted_str: String = match sc!("Hello world!", 20) {
        Ok(s) => s,
        Err(e) => panic!("Decryption failed: {:?}", e),
    };

    println!("Decrypted string: {}", encrypted_str);
}

Add str_crypter to your Cargo.toml:

[dependencies]
str_crypter = "1.0.1"

Or use the command cargo add str_crypter
