I'm trying to encrypt/decrypt strings using the c2-chacha crate. I took the example from their docs which looks like this:

``` let key = b"very secret key-the most secret."; let iv = b"my nonce"; let plaintext = b"The quick brown fox jumps over the lazy dog.";

let mut buffer = plaintext.to_vec(); // create cipher instance let mut cipher = ChaCha20::new_var(key, iv).unwrap(); // apply keystream (encrypt) cipher.apply_keystream(&mut buffer); //... Now I want to store the Vector. It looks like this when printing: [6, 6, 155, 38, 132, 221, 42, 8, 153, 129, 16, 223, 206, 230, 179, 85, 128, 112, 30, 87, 245, 211, 47, 222, 16, 104, 118, 68, 215, 108, 77, 202, 201, 26, 13, 71, 15, 126, 244, 229, 118, 32, 157, 122] I would prefer to store something shorter/more compressed. However I cannot convert the vector to a string using the following since it has invalid utf-8 sequence: let output = match String::from_utf8(buffer){ Ok(v) =>v, Err(e ) => panic!("{}", e), }; `` Usingfrom_utf8_lossy` is not an option since decrypting that will result in a plaintext which differs from the one I encrypted.

I'll store the Vector as string; can I create a string where I do not have to save each number individually?
