Usage

npm install @sorairolake/scryptenc-wasm

wasm-pack build

import * as assert from "https://deno.land/std@0.216.0/assert/mod.ts";

import * as scryptenc from "./pkg/scryptenc_wasm.js";

const data = new TextEncoder().encode("Hello, world!\n");
const passphrase = new TextEncoder().encode("passphrase");

// Encrypt `data` using `passphrase`.
const ciphertext = scryptenc.encrypt(data, passphrase);
assert.assertNotEquals(ciphertext, data);

// And extract the scrypt parameters from it.
const params = new scryptenc.Params(ciphertext);
assert.assertEquals(params.logN, 17);
assert.assertEquals(params.n, BigInt(2 ** 17));
assert.assertEquals(params.r, 8);
assert.assertEquals(params.p, 1);

// And decrypt it back.
const plaintext = scryptenc.decrypt(ciphertext, passphrase);
assert.assertEquals(plaintext, data);
