bcrypt-wasm-rust

Optimized bcrypt implementation in WASM, written in rust.

---

Functionalities

• Hash passwords
• Custom rounds for salt
• Verify hashed passwords
• Faster than the pure JS implementation

Instructions to run

• Pre-requisites:
  • NPM

Installation with NPM

npm i -s bcrypt-rust-wasm

Usage

This library is currently compatible with NodeJS and supports the synchronous bindings only.

Importing

const { Bcrypt } = require('bcrypt-rust-wasm');
...

Obtaining an instance

// Get a bcrypt instance with a default number of seed rounds
const bcryptDefault = Bcrypt.default();

// Get a bcrypt instance with a specified number of seed rounds
const bcrypt = Bcrypt.new(10);

Hashing

const hash = bcrypt.hashSync('password'); 
// hash: "$2b$04$fsiGFAMtgNJ8YIszhoxusObEgoLF.faqMIKXiRDp5GZbzFWzebgcu"

Verifying a hash

bcrypt.verifySync("password", hash) // true
bcrypt.verifySync("password123", hash) // false
