react-native-bcrypt-cpp

Next-gen React Native library for Bcrypt hashing using pure C++ with Turbo Modules and multithreading for superior performance.

NOTE: This library can be used only with New Architecture (more information about New Architecture here)

Installation

npm install react-native-bcrypt-cpp

or

yarn add react-native-bcrypt-cpp

Usage

Asynchronous Hashing (Multithreaded)

import { generateHash, validatePassword } from 'react-native-bcrypt-cpp';

// Generate a hash asynchronously
const hash = await generateHash('password', 12);

// Validate a password against a hash
const isValid = await validatePassword('password', hash);

Synchronous Hashing (Single-threaded)

import {
  generateHashSync,
  validatePasswordSync,
} from 'react-native-bcrypt-cpp';

// Generate a hash synchronously
const hash = generateHashSync('password', 12);

// Validate a password against a hash synchronously
const isValid = validatePasswordSync('password', hash);

API Reference

API Reference

generateHash(password: string, workload: number): Promise<string>

Asynchronously generates a Bcrypt hash for the given password with the specified workload factor.

Parameters:

• password (string): The password to hash.
• workload (number): The cost factor for the hashing algorithm (e.g., 12).

Returns:

• A Promise that resolves to a string containing the generated hash.

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

Asynchronously validates the given password against the Bcrypt hash.

Parameters:

• password (string): The password to validate.
• hash (string): The Bcrypt hash to validate against.

Returns:

• A Promise that resolves to a boolean indicating whether the password is valid.

generateHashSync(password: string, workload: number): string

Synchronously generates a Bcrypt hash for the given password with the specified workload factor.

Parameters:

• password (string): The password to hash.
• workload (number): The cost factor for the hashing algorithm (e.g., 12).

Returns:

• A string containing the generated hash.

validatePasswordSync(password: string, hash: string): boolean

Synchronously validates the given password against the Bcrypt hash.

Parameters:

• password (string): The password to validate.
• hash (string): The Bcrypt hash to validate against.

Returns:

• A boolean indicating whether the password is valid.
