keygen-py 0.0.1.dev4

Unofficial Keygen SDK for Python. Integrate license activation and offline licensing. Wrapper around keygen-rs rust crate

Unofficial Keygen Python SDK

The keygen-py package allows Python programs to license using the keygen.sh service. This is a wrapper around the rust package keygen-rs (so a lot of kudos there) to provide python bindings.

Installing

Add this to your pyproject.toml:

[dependencies]
keygen-py = "0.0.1.dev1"

Config

KeygenConfig

Use KeygenConfig to configure the SDK globally. You should set this before making any API calls.

from keygen_sh import set_config, KeygenConfig

set_config(KeygenConfig(
    api_url="https://api.keygen.sh",
    api_prefix="v1",
    api_version="v1.7",
    account="YOUR_KEYGEN_ACCOUNT_ID",
    product="YOUR_KEYGEN_PRODUCT_ID",
    license_key="A_KEYGEN_LICENSE_KEY",
    public_key="YOUR_KEYGEN_PUBLIC_KEY"
))

Usage

Validate a License

To validate a license, configure KeygenConfig with your Keygen account details. Then call the validate function with a device fingerprint (you can use py-machineid for this) or keep it empty depending on your policy:

import asyncio
from keygen_sh import validate

async def amain():
    data = await validate(["YOUR_DEVICE_FINGERPRINT"], [])
    
    # License
    print(data.id, data.name, data.key, data.expiry)

if __name__ == '__main__':
    asyncio.run(amain())

Offline License Key Verification

To verify a signed license key offline:

from keygen_sh import verify, SchemeCode

data = verify(SchemeCode.Ed25519Sign, "A_KEYGEN_LICENSE_KEY")

# data encoded
print(data)

Examples

For more detailed examples, please refer to the examples directory in the repository.

Testing

When implementing a testing strategy for your licensing integration, we recommend mocking the Keygen API responses. This is especially important for CI/CD environments to prevent unnecessary load on Keygen's servers and to stay within your account's daily request limits.
