 # react-native-bcrypt-cpp
 
-Bcrypt implemented in pure C++ and linked to  React Native using Turbo Modules
+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](https://github.com/reactwg/react-native-new-architecture))
 
 ## Installation
 
 ```sh
 npm install react-native-bcrypt-cpp
 ```
 
+or
+
+```sh
+yarn add react-native-bcrypt-cpp
+```
+
 ## Usage
 
+### Asynchronous Hashing (Multithreaded)
+
+```js
+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)
 
 ```js
 import {
-  generateHash,
   generateHashSync,
-  validatePassword,
   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.
