# The one thing this connector needs beyond Python itself.
#
# `cryptography` supplies Ed25519, X25519 and ChaCha20-Poly1305 — the same
# three primitives the app uses. Nothing else is required: the HTTP reading is
# the standard library, and the MQTT subscriber is four packet types written
# out rather than a broker client with a publish path to review.
