aead-io

Provides a wrapper around a Write/Read object and a StreamPrimitive to provide an easy interface for doing correct encryption.

let key = b"my very super super secret key!!".into();
let plaintext = b"hello world!";

let ciphertext = {
    let mut ciphertext = Vec::default();
    let mut writer = EncryptBE32BufWriter::<ChaCha20Poly1305, _, _>::new(
        key,
        &Default::default(), // please use a better nonce ;)
        Vec::with_capacity(128),
        &mut ciphertext,
    )
    .unwrap();
    writer.write_all(plaintext)?;
    writer.flush()?;
    ciphertext
};

let decrypted = {
    let mut reader = DecryptBE32BufReader::<ChaCha20Poly1305, _, _>::new(
        key,
        Vec::with_capacity(256),
        ciphertext.as_slice(),
    )
    .unwrap();
    let mut out = Vec::new();
    let _ = reader.read_to_end(&mut out).unwrap();
    out
};

assert_eq!(decrypted, plaintext);

no_std

This package is compatible with no_std environments. Just disable the default features, and implement the Buffer, CappedBuffer, ResizeBuffer, Write and Read accordingly. There should be some default implementations for Vec<u8> and byte slices
