# node-essential-crypto-utils

A Node.js library providing essential cryptographic utilities for text encryption, decryption, and file hashing.

## Installation

```bash
npm install node-essential-crypto-utils

Usage

const { NodeEssentialCryptoUtils } = require('node-essential-crypto-utils');

// Encrypt text
const encryptedText = NodeEssentialCryptoUtils.encryptText('mySecretText', 'mySecretKey');

// Decrypt text
const decryptedText = NodeEssentialCryptoUtils.decryptText(encryptedText, 'mySecretKey');

// Hash a file
NodeEssentialCryptoUtils.hashFile('path/to/file').then(hash => {
  console.log('File hash:', hash);
}).catch(error => {
  console.error('Error:', error);
});

API

NodeEssentialCryptoUtils

encryptText(text, secret, algorithm)

Encrypts the provided text using the specified secret and algorithm. Returns the encrypted text.

• text: The text to encrypt.
• secret: The secret key used for encryption.
• algorithm (optional): The encryption algorithm to use. Defaults to 'aes-256-cbc'.

decryptText(encryptedText, secret, algorithm)

Decrypts the provided encrypted text using the specified secret and algorithm. Returns the decrypted text.

• encryptedText: The text to decrypt.
• secret: The secret key used for decryption.
• algorithm (optional): The decryption algorithm to use. Defaults to 'aes-256-cbc'.

hashFile(filePath, algorithm)

Hashes the file located at the specified file path using the specified algorithm. Returns a Promise that resolves with the computed hash value.

• filePath: The path to the file to hash.
• algorithm (optional): The hashing algorithm to use. Defaults to 'sha256'.
