# 🔒 Huawei Modem Encryption A **JavaScript library** for RSA encryption used by Huawei modems. This library provides functionality to encrypt passwords and other sensitive data using **RSA PKCS#1** with both padding types. ## 📦 Installation ```sh npm install huawei-modem-encryption ``` ## 🚀 Usage ```javascript import { doRSAEncrypt } from 'huawei-modem-encryption'; // Example usage: const encryptedString = doRSAEncrypt( "password", // 🔑 String to encrypt publicKeyN, // 🔐 RSA public key modulus (n) publicKeyE, // 🔐 RSA public key exponent (e) 0 // 🔓 Login status is 0 (logged in) ); ``` ### 📝 Parameters - **`string`**: The data to be encrypted (e.g., password) 🔑 - **`publicKeyN`**: The RSA public key modulus (n) 🔐 - **`publicKeyE`**: The RSA public key exponent (e) 🔐 - **`loginStatus`**: `0` for logged in 🔓 > **Note**: The public key (`n` and `e`) should be obtained from your Huawei modem's API or documentation. ## ✨ Features - 🔐 **RSA encryption** with PKCS#1 v1.5 and OAEP padding support - 📜 **Base64 encoding** of encrypted data - 🎲 **Built-in secure random number generation** - 🛡️ **SHA-1 hashing** for OAEP padding ## 📜 License BSD License This package contains code derived from Tom Wu's RSA implementation.
