1 Web Crypto API Examples

This collection provides a practical introduction to the Web Crypto API, the modern standard for performing cryptographic operations in the browser. The examples demonstrate fundamental tasks like hashing data with SHA-256, generating secure random values, and encrypting/decrypting information using AES-GCM. You’ll explore the API’s promise-based, asynchronous nature, a key technical aspect for non-blocking UI. These demos showcase how to build secure, client-side features without exposing sensitive data to the server, directly using browser-native capabilities.
