End-to-end encryption (E2EE) is a system of communication where only the communicating parties can read the messages. E2EE is designed to prevent third parties – like governments, internet service providers, and hackers – from accessing communication content. E2EE is a form of security that helps protect your information from being read by anyone except the intended recipient. When you make a payment online, your credit card number and other personal information are encrypted before it's transmitted over the internet. This ensures that your information remains private and secure.
