API

hash(password: string): Promise<string>
verify(password: string, hash: string): Promise<boolean>

Usage

import { hash, verify } from "https://deno.land/x/bcrypt_ffi/mod.ts";

const password = "password";

const hashed = await hash(password);
const isMatch = await verify(password, hashed);
console.log(hashed, isMatch);
