License validation SDK for Bim Plugins applications via local license server

BimPlugins Licensing SDK

A secure Python SDK for validating licenses with the BIM Plugins Local License Server.

Overview

The BimPlugins Licensing SDK provides a simple interface for applications to check license validity through a local license server. The SDK handles secure communication via Windows named pipes, including cryptographic handshake and AES-256 encryption.

Requirements

• Python: 3.10 or higher
• Operating System: Windows only (uses Windows named pipes and registry)
• Dependencies:
  • pycryptodome - Cryptographic operations
  • netifaces-plus - Network interface information

Installation

Install via pip:

pip install bimplugins-licensing-sdk-sds2

Quick Start

from bimplugins.LicenseManager import LicenseManager
from bimplugins.Models import ResponseStatus

# Check license for your application
response = LicenseManager.CheckForLicense("your-application-id")

# Check the response status
if response.status == ResponseStatus.Success:
    print(f"License valid until: {response.license_expires_at}")
elif response.status == ResponseStatus.Expiring:
    print(f"License is expiring soon! Expires: {response.license_expires_at}")
else:
    print(f"License check failed: {response.error_message} \t status: {response.status}")

API Reference

LicenseManager

The main entry point for license validation.

Methods

CheckForLicense(application_id: str) -> LicenseCheckResponse

Checks for a valid license for the specified application ID.

• Parameters:

  • application_id (str): The ID of the application to check

• Returns: LicenseCheckResponse object containing license information and status

LicenseCheckResponse

Response object containing license validation results.

Properties

• request_id (str): Unique identifier for this request
• status (ResponseStatus): Status code indicating the result
• license_expires_at (datetime): Expiration date/time of the license (if valid)
• error_message (str): Error description (if applicable)
• is_trial (bool): Whether this is a trial license
• trial_ends_at (datetime | None): Trial expiration date (if trial license)

ResponseStatus Enum

Status	Value	Description
Success	200	License is valid and active
Expiring	201	License is valid but expiring within 7 days
BadRequest	400	Invalid request format
LicenseExpired	401	License has expired
LicenseNotFound	404	No license found for application
InternalError	500	Internal server error
LicenseNotAssigned	503	License exists but not assigned
ServerNotAvailable	504	License server is not running
CheckoutExpired	505	License checkout has expired
TrialExpired	506	Trial license has expired

LicenseCheckRequest

Request object for license validation (typically used internally).

Properties

• request_id (str): Unique identifier (auto-generated)
• request_time (datetime): Request timestamp (auto-generated)
• application_id (str): The application ID to validate

Error Handling

The SDK communicates with a local license server via named pipe. Common failure scenarios:

from bimplugins.LicenseManager import LicenseManager
from bimplugins.Models import ResponseStatus

response = LicenseManager.CheckForLicense("my-app-id")

if response.status == ResponseStatus.ServerNotAvailable:
    print("License server is not running. Please start the BIM Plugins Local License Server.")
elif response.status == ResponseStatus.LicenseNotFound:
    print("No license found for this application.")
elif response.status == ResponseStatus.LicenseExpired:
    print("Your license has expired. Please renew your subscription.")
elif response.status == ResponseStatus.TrialExpired:
    print(f"Your trial has ended (expired {response.trial_ends_at}). Please purchase a license.")
elif response.status == ResponseStatus.CheckoutExpired:
    print("License checkout has expired. Please reconnect to the license server.")
elif response.status == ResponseStatus.Expiring:
    print(f"License valid but expiring soon on {response.license_expires_at}.")
    if response.is_trial:
        print(f"Trial ends: {response.trial_ends_at}")
elif response.status == ResponseStatus.Success:
    print("License validated successfully!")

Platform Requirements

This SDK is designed exclusively for Windows platforms and requires:

• The BIM Plugins Local License Server to be installed and running
• Valid Windows registry entries for machine identification
• Named pipe access (\\.\pipe\BimPlugins)

Security

All communications between the SDK and the local license server are encrypted using AES-256-CBC encryption with a machine-specific key derivation. The SDK source code is obfuscated to protect the licensing implementation.
