BCrypt

This is a port from jBCrypt to TypeScript for use in Deno.

It has zero third-party dependencies.

Running in sync requires no permissions. Running in async functionality requires --allow-net

Import

If you don't want to specify a specific version and are happy to work with breaking changes, you can import this module like so:

import * as bcrypt from "https://deno.land/x/bcrypt/mod.ts";

To ensure that you've got a specific version, it's recommend to import this module specifying a specific release like so:

import * as bcrypt from "https://deno.land/x/bcrypt@v0.3.0/mod.ts";

Usage

Async

The Async implementation requires WebWorkers which require --allow-net to import Deno standard modules from inside the Worker.

const hash = await bcrypt.hash("test");

To check a password:

const result = await bcrypt.compare("test", hash);

To hash a password with a manually generated salt:

const salt = await bcrypt.genSalt(8);
const hash = await bcrypt.hash("test", salt);

Sync/Blocking

It is not recommended to use this unless you're running a quick script since the BCrypt algorithm is computationally quite expensive. For example, if you're running a server and make multiple calls to it, other requests will be blocked. Using the Async methods are recommended.

To hash a password (with auto-generated salt):

const hash = bcrypt.hashSync("test");

To check a password:

const result = bcrypt.compareSync("test", hash);

To hash a password with a manually generated salt:

const salt = bcrypt.genSaltSync(8);
const hash = bcrypt.hashSync("test", salt);

Older versions of Deno and/or BCrypt

Older versions of Deno will require an older version of this library (specifically < 0.3.0) because of the introduction of TextEncoder. However, older version of this library require the --unstable flag when running.
