NULL Protocol, or the message that leaves almost nothing behind

Field notes

The specification gives concrete wire-level constraints rather than only describing private messaging in general terms. It lists a 16 KiB request and 8 KiB response shape, uses OHTTP to separate address and content visibility, and describes discovery as downloading the whole directory for local resolution. A browser or Node integrator is shown importing the NULL SDK directly from a nullchat.me URL, while keys are stated to remain client-side.
