End-to-end encryptionUnderstand the seal.
Know its limits.

End-to-end encryption explained: message keys, encrypted groups, verification, recovery and the boundaries that matter.

Start with a simple question: who can read the message? These guides explain end-to-end encryption through the things people actually do: send a photo, join a group, verify a contact, or restore a conversation.

Follow the details as far as you need. The collection covers message keys, sender-key groups, identity verification and the places where encryption stops protecting a conversation.
