Module dryoc::crypto_secretbox

Authenticated encryption functions

Implements libsodium’s secret-key authenticated crypto boxes.

For details, refer to libsodium docs.

Classic API example

use dryoc::rng::randombytes_buf;
use dryoc::crypto_secretbox::{crypto_secretbox_keygen, crypto_secretbox_easy, crypto_secretbox_open_easy};
use dryoc::constants::CRYPTO_SECRETBOX_NONCEBYTES;
use dryoc::nonce::Nonce;
use dryoc::traits::*;

let key = crypto_secretbox_keygen();
let nonce = randombytes_buf(CRYPTO_SECRETBOX_NONCEBYTES);
let nonce = Nonce::gen();

let message = "I Love Doge!";

// Encrypt
let ciphertext = crypto_secretbox_easy(message.as_bytes(), &nonce, &key).unwrap();

// Decrypt
let decrypted = crypto_secretbox_open_easy(&ciphertext, &nonce, &key).unwrap();

assert_eq!(decrypted, message.as_bytes());

Functions

crypto_secretbox_detached	Detached version of crypto_secretbox_easy
crypto_secretbox_easy	Encrypts message with nonce and key
crypto_secretbox_easy_inplace	Encrypts message with nonce and key in-place, without allocating additional memory for the ciphertext
crypto_secretbox_keygen	Generates a random key using randombytes_buf
crypto_secretbox_open_detached	Detached version of crypto_secretbox_open_easy
crypto_secretbox_open_easy	Decrypts ciphertext with nonce and key
crypto_secretbox_open_easy_inplace	Decrypts ciphertext with nonce and key in-place, without allocating additional memory for the message
