You will need wasm-pack to build this crate.

wasm-pack build

This will generate build artifacts in the pkg directory.

Example

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

import * as abcrypt from "./pkg/abcrypt_wasm.js";

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

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

// And extract the Argon2 parameters from it.
const params = new abcrypt.Params(ciphertext);
assert.assertEquals(params.memoryCost, 19456);
assert.assertEquals(params.timeCost, 2);
assert.assertEquals(params.parallelism, 1);

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