Radek de17686a9b Update README and notes for DRBG, health checks, and HTTP service

Rewrite README to reflect the actual pipeline (frame -> health check
-> SHA-256 -> HMAC-DRBG -> emit), document all entropy.py flags, the
HTTP service endpoints and env vars, container build/run, Kubernetes
notes, and the remote-consumption rngd flow. Fix the notes.md typos
and align its commands with the new --out flag.

Raw Blame History

In order to use this there needs to be an IP webcam with a stream available to use as the randomness generating source.

Suggest reviewing the code to see how it should be provided to the script.

generate entropy via a pipe file

mkfifo /tmp/entropy.fifo python3 entropy.py --loop --bit 512 --out /tmp/entropy.fifo &

Use the generated entropy

sudo rngd -f -W 90% -x rdrand -x jitter -x pkcs11 -x rtlsdr -O namedpipe:path:/tmp/entropy.fifo -O namedpipe:timeout:2

Or serve it over HTTP for remote systems (see README -> HTTP Service)

uvicorn api:app --host 0.0.0.0 --port 8000
