Usage

Library

import { assert } from "https://deno.land/std/testing/asserts.ts";
import { hash, verify } from "https://deno.land/x/argon2/lib/mod.ts";

let hash = await hash("test");

assert(await verify(hash, "test"));

Testing

import { Variant } from "https://deno.land/x/argon2/lib/mod.ts";
import { assertArgon2Encoded } from "https://deno.land/x/argon2/lib/testing.ts";

Deno.test("User#password should be an argon2id variant password", async () => {
  assertArgon2Encoded(user.password, {
    variant: Variant.Argon2id,
  });
});
