 This section documents the current design and scope; it is not a judgment that the
 design is optimal or that it will not change.
 
-## OTA update encryption
-
-The `esphome` OTA platform optionally encrypts updates with the same Noise
-`NNpsk0` pattern the native API uses; one key protects the device. With an
-`encryption:` block configured the guarantees are: the firmware image is
-confidential in transit, the uploader is authenticated by the pre-shared key,
-and the plaintext negotiation preceding the handshake is bound into the
-handshake prologue, so stripping or tampering with it fails the first MAC.
-Both ends fail closed with no override: a device built with a key refuses
-plaintext uploads, and the CLI refuses to send plaintext when a key is
-configured.
-
-Defeating any of that without the key is in scope: a keyed device accepting a
-plaintext or downgraded upload, getting past the MAC, or recovering image
-contents from captured traffic.
-
-The following are **not** vulnerabilities, by design:
-
-- Plaintext OTA on a device with no `encryption:` block. That is the
-  documented default, authenticated (if at all) by the OTA password.
-- The enablement window: turning encryption on takes one last upload of the
-  encryption-enabled firmware over the existing plaintext channel, with the
-  pre-existing plaintext exposure.
-- The captive portal's update endpoint. `captive_portal:` auto-loads the web
-  OTA platform, and while the fallback AP is active its plaintext `/update`
-  endpoint is reachable on that AP; validation warns about the combination.
-  Combining `encryption:` with the always-on `web_server` component is a
-  config error instead.
-- CLI retry behavior on transport or MAC failures; every attempt renegotiates
-  a fresh handshake with fresh ephemerals, so retrying does not weaken
-  authentication.
-
 ## Explicitly out of scope
 
 - Local attackers who already have shell access on the host that runs `esphome`.
