Crate scryptenc

The scryptenc crate is an implementation of the scrypt encrypted data format.

The format is defined here.

Examples

Encrypt and decrypt

use scryptenc::{Decryptor, Encryptor};

let password = "password";
let data = b"Hello, world!";

// Encrypt `data` using `password`.
let params = scrypt::Params::new(10, 8, 1).unwrap();
let cipher = Encryptor::with_params(data, password, params);
let encrypted = cipher.encrypt_to_vec();
assert_ne!(encrypted, data);

// And decrypt it back.
let cipher = Decryptor::new(encrypted, password).unwrap();
let decrypted = cipher.decrypt_to_vec().unwrap();
assert_eq!(decrypted, data);

Extract the scrypt parameters in the encrypted data

use scryptenc::{Encryptor, Params};

let password = "password";
let data = b"Hello, world!";

// Encrypt `data` using `password`.
let params = scrypt::Params::new(10, 8, 1).unwrap();
let cipher = Encryptor::with_params(data, password, params);
let encrypted = cipher.encrypt_to_vec();

// And extract the scrypt parameters from it.
let params = Params::new(encrypted).unwrap();
assert_eq!(params.log_n(), 10);
assert_eq!(params.n(), 1024);
assert_eq!(params.r(), 8);
assert_eq!(params.p(), 1);
