Common Encryption Utility

A JavaScript module for one-way and two-way encryption using crypto-js. Supports hashing with SHA-256 and AES encryption/decryption. Supports both browser as well as node.

Notes

When encrypting it will aways assume the encryption of text, if the input is a object its going to be stringified but whe decryting it will allways return text.

Features

• One-way encryption: Hash data using SHA-256.
• One-way comparison: Compare hashed data.
• Two-way encryption: Encrypt data using AES with a passphrase.
• Two-way decryption: Decrypt AES-encrypted data.

Installation

npm install base-encryption

Usage

Importing the Module

import commonEncryption from 'common-encryption';

One-Way Encryption (SHA-256 Hashing)

const sha = true;
const hash = commonEncryption.oneWayEncrypt("mySecretData", sha);
console.log(hash); // Output: SHA-256 hash of "mySecretData" if sha is true or MD5 if false

One-Way Comparison

const isMatch = commonEncryption.oneWayCompare(hash, "mySecretData", sha);
console.log(isMatch); // Output: true or false

Two-Way Encryption (AES)

const passphrase = "mySecurePassphrase";
const encryptedData = commonEncryption.twoWayEncrypt("Sensitive Data", passphrase);
console.log(encryptedData); // Output: AES encrypted string

Two-Way Decryption

const decryptedData = commonEncryption.twoWayDecrypt(encryptedData, passphrase);
console.log(decryptedData); // Output: "Sensitive Data"

Technical Details

• Uses AES-256-CBC for two-way encryption.
• Salt and IV are randomly generated.
• PBKDF2 is used for key derivation with 100 iterations.
