gdgvit / bcrypt-rust-wasm

Bcrypt implementation for WASM, written in Rust.

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

bcrypt-rust-wasm's Issues

Benchmark library and compare with the pure js implementation

It would be helpful for potential users to see the difference in speed between bcrypt.js and this library. Add it to the readme when done.

Bonus points for adding graphics like charts.

Update the readme

The readme has to be updated. In the verification of password, it should be verifySync instead of verify.
