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.
This was originally turned into a 2.0 crate, however after additional testing the crate was not working as intended, so I have yanked those versions and reverted it to an older working copy under v1. The changes made in 2.0 weren't particularly groundbreaking nor did it add extra functionality, so I have no issues yanking it and working on it again when I have some more time.
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]
