hymmalm 0.1.4

Python wrapper for license-management-core (License-Management.com client)

hymmalm — Python wrapper

Python (ctypes) binding for license-management-core. All licensing behavior — JWS verification, status rules, machine fingerprint, REST flow, retry policy, clock-tamper resistance — lives in the native hymmalm library; this package only marshals. See the repository root README for the architecture.

Usage

from hymmalm import LicenseClient, LicenseStatus

client = LicenseClient(
    product_id="PRD_01KWWPEPM0N070BDAHJ7G09RGV",
    client_api_key="PUB_...",                    # never a MST_ key
    jwks_json=open("signingkeys.json").read(),   # GET /api/signingkeys.json
    license_path="~/.myapp/license.lic",
)

status = client.check()                          # trial bootstrap on first run
if status == LicenseStatus.INVALID_TRIAL:
    client.activate(input("Receipt code: "))

Offline verification only (no network, e.g. checking a provisioned file):

import hymmalm
status = hymmalm.verify(jws_string, jwks_json)

Installing

pip install hymmalm

Release wheels bundle the native library per platform (manylinux x86_64 / aarch64, macOS arm64 / x86_64, Windows x64) — nothing else to install.

From a source checkout (or the sdist), build the core once (cmake -S . -B build && cmake --build build at the repo root) and either place libhymmalm.so / libhymmalm.dylib / hymmalm.dll next to the hymmalm package, on the loader path, or point HYMMALM_LIB at the full path.

Publishing

CI publishes to PyPI on v* release tags (the pypi job): it drops each platform's freshly built library into the package, builds a py3-none-<platform> wheel per OS/arch (linux wheels retagged and vetted by auditwheel), plus a pure sdist, and uploads with PYPI_API_TOKEN.

Tests

cd wrappers/python
HYMMALM_LIB=$PWD/../../build/libhymmalm.so python -m unittest discover -s tests -v

tests/test_vectors.py replays the same signed vectors as the C suite; tests/test_flow.py runs the full client flow (trial → activate → offline cache → deactivate, plus error classification) against a local mock API.
