"""make_manifest.py - build + sign the release manifest for the updater.
|
|
|
|
Usage:
|
|
python3 scripts/make_manifest.py --version 1.0.1 \
|
|
--priv release_priv.pem \
|
|
--bin build/orbisrpc.elf \
|
|
--prx plugin/build/orbisrpc_plugin.prx \
|
|
--pkg build/pkg/OrbisRPC-1.0.1.pkg \
|
|
--out build/pkg/manifest.json
|
|
|
|
Outputs manifest.json + manifest.sig (raw 64-byte r||s, hex file) +
|
|
appends SHA256SUMS for back-compat. The daemon verifies manifest.sig
|
|
with orbisrpc/release_pubkey.h and refuses updates on mismatch
|
|
(ORX-UPDATE-002). Keep release_priv.pem OFFLINE, out of the repo.
