Encryption is the process of encoding data so that only authorized parties with the correct decryption key can read it. End-to-end encrypted communications (like Signal or WhatsApp) mean that only the sender and recipient can read messages — not the platform or third parties. For creators, encryption is relevant to protecting sensitive business communications, securing payment data, and understanding platform privacy policies. HTTPS encryption on websites protects user data in transit and is a baseline requirement for SEO and audience trust.
