Simplest way to perform a symmetric encryption, using a preshared key. Very small wrapper around aes-siv crate, with randomly generated nonces, for anything more advanced, use aes-siv instead
``` rust use std::str; fn main() { let payload = "Hello world!".as_bytes(); let password = b"hello wooooooooo";
let encrypted = simplestcrypt::encrypt_and_serialize(&password[..], &payload).unwrap();
let plain = simplestcrypt::deserialize_and_decrypt(&password[..], &encrypted).unwrap();
println!("{:?}", str::from_utf8(&plain));
} ```
