Using npm (Recommended for Node.js)The most common way to download the library is through npm. This ensures you have the latest stable version and makes dependency management easier. npm install crypto-js

Using YarnIf you prefer Yarn, the command is equally simple: yarn add crypto-js

// Decryptvar bytes = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');var originalText = bytes.toString(CryptoJS.enc.Utf8); console.log(originalText); // 'my secret message' Best Practices for Usage

⚡ Light and FastThe library is modular. You can import only the specific algorithms you need to keep your bundle size small.

// Encryptvar ciphertext = CryptoJS.AES.encrypt('my secret message', 'secret key 123').toString();

CDN for Browser UseFor quick prototyping or projects without a build step, you can include Crypto-JS via a CDN like cdnjs or unpkg. This allows you to skip the download entirely and load the scripts directly. Key Features and Algorithms
