Bazel/bzlmod build (abseil-cpp/BoringSSL/protobuf/tink_cc), no CMake path; bazel 9.1.0 + rules_python 2.2.0 already carry riscv64 support so no rules_python/rules_java override is needed, unlike the bazel 7.x era ports.
tink-py builds its C++ pybind11 extension entirely through Bazel (bzlmod, no WORKSPACE), pulling abseil-cpp, BoringSSL (via tink_cc), protobuf and pybind11 as source deps -- all of which already have riscv64 precedent elsewhere in this repo. Bazel publishes no riscv64 release binary, so it is bootstrapped from the dist archive as in build-ray.yml/build-array-record.yml; unlike those, tink-py's pinned bazel 9.1.0 and rules_python 2.2.0 already carry riscv64 support, so no rules_python/rules_java override is needed.

tink1.16.1Compiles Tink's pybind11 C++ extension (AEAD/MAC/signature/KMS crypto primitives, statically linking BoringSSL, abseil-cpp, protobuf and tink_cc through Bazel/bzlmod). Upstream publishes no riscv64 wheel.
Mirrors upstream's
tools/distribution/build_linux_binary_wheels.sh(tink-py has no GitHub Actions CI; releases build via Kokoro).Differs from upstream
Testing
*_test.pysuite against the installed wheel, excludingtink/integration/- those call live AWS/GCP/Vault KMS services this CI has no credentials forLicense: wheel bundles BoringSSL, abseil-cpp, protobuf and tink_cc (Apache-2.0/BSD-3-Clause/mixed OpenSSL-derived) and pybind11 (BSD-3-Clause); upstream ships none of their license texts, so the build adds them.
Patches
0001-Package-the-vendored-C-dependencies-licences.patch- To upstream. AddsLICENSE.<dep>for the statically-linked dependencies above; reproduces on any platform, not just riscv64.Built on cp312; TBD passed, TBD skipped.
