End-to-End Encryption with Convex

Lee Danilek explores the implementation of end-to-end encryption using Convex by developing a tool called Whisper, designed to securely send encrypted messages. Whisper encrypts messages on the sender's device and allows them to be decrypted only by the recipient, ensuring that no unencrypted data is exposed during transmission. Users can send messages without needing to log in or set up accounts, and they can track IP addresses if the message URL is intercepted. Messages can expire after a set number of accesses or time, triggering automatic deletion from Convex. The encryption utilizes AES symmetric encryption, and the tool operates primarily through client-side code, never exposing raw URLs or secrets to Convex servers. Danilek provides the source code for Whisper, showcasing its backend operations with Convex, which supports scalable and secure full-stack development.
