Offline SDKs for importing RSA keys into a local vault and decrypting CENC-encrypted MP4 files.

This repository hosts multiple language ports of the same SDK. The wire format, vault layout, and error codes live in spec/ and are the source of truth for every implementation.

spec/             Format spec & error taxonomy — language-agnostic source of truth
test-vectors/     Shared fixtures: sample RSA keys, encrypted samples, expected outputs
python/           Python SDK (pyproject.toml, src/, tests/, scripts/)
ruby/             Ruby SDK (gemspec, lib/, test/)
robocap-vault/    Sample on-disk vault (language-agnostic runtime artifact)

Every SDK is expected to pass against the same fixtures under test-vectors/. A change to the binary format requires updating spec/ and both SDKs in the same PR.

# Python
cd python && pip install -e ".[dev,web]" && pytest

# Ruby
cd ruby && bundle install && bundle exec rake test

The keys under test-vectors/ and robocap-vault/ are test fixtures only. Never use them in production.
