exisone-client 0.9.0

Python client SDK for ExisOne Software Activation System

ExisOne Python Client SDK

Official Python client SDK for the ExisOne Software Activation System.

Installation

pip install exisone-client

Quick Start

from exisone import ExisOneClient, ExisOneClientOptions

# Initialize the client
options = ExisOneClientOptions(
    base_url="https://www.exisone.com",
    access_token="your-api-token"
)
client = ExisOneClient(options)

# Generate a hardware fingerprint for this machine
hardware_id = client.generate_hardware_id()

# Activate a license
result = client.activate(
    activation_key="XXXX-XXXX-XXXX-XXXX",
    email="[e-mail]",
    hardware_id=hardware_id,
    product_name="MyProduct"
)

if result.success:
    print("License activated successfully!")
else:
    print(f"Activation failed: {result.error_message}")

Features

• License Activation - Activate licenses on specific hardware
• License Validation - Validate licenses online or offline
• Smart Validation - Auto-detects offline vs online keys with fallback
• Hardware ID Generation - Cross-platform hardware fingerprinting
• Offline Support - Validate licenses without internet using RSA signatures
• Type Hints - Full type annotation support (PEP 561)

API Reference

ExisOneClientOptions

Configuration options for the client:

Option	Type	Description
base_url	str	Base URL for the ExisOne API (must use HTTPS)
access_token	str	API access token for authentication
offline_public_key	str	RSA public key (PEM) for offline validation
allowed_base_url_hosts	list[str]	Restrict base_url to specific hosts
timeout	int	Request timeout in seconds (default: 30)

ExisOneClient Methods

generate_hardware_id() -> str

Generate a cross-platform hardware fingerprint for this machine.

hardware_id = client.generate_hardware_id()
# Returns: "A1B2C3D4E5F6..." (64-char hex string)

activate(activation_key, email, hardware_id, product_name, version=None) -> ActivationResult

Activate a license on this machine.

result = client.activate(
    activation_key="XXXX-XXXX-XXXX-XXXX",
    email="[e-mail]",
    hardware_id=hardware_id,
    product_name="MyProduct",
    version="1.0.0"  # Optional: your app version
)

if result.success:
    print(f"Server version: {result.server_version}")
else:
    print(f"Error: {result.error_code} - {result.error_message}")

validate(activation_key, hardware_id, product_name=None, version=None) -> ValidationResult

Validate a license online.

result = client.validate(
    activation_key="XXXX-XXXX-XXXX-XXXX",
    hardware_id=hardware_id
)

if result.is_valid:
    print(f"License valid until: {result.expiration_date}")
    print(f"Features: {', '.join(result.features)}")

validate_smart(key_or_code, hardware_id, product_name=None) -> SmartValidationResult

Smart validation that auto-detects offline vs online keys.

# Works with both online keys and offline codes
result = client.validate_smart(
    activation_key_or_offline_code="XXXX-XXXX-XXXX-XXXX",
    hardware_id=hardware_id
)

print(f"Valid: {result.is_valid}")
print(f"Was offline: {result.was_offline}")

deactivate(activation_key, hardware_id, product_name) -> bool

Deactivate a license.

success = client.deactivate(
    activation_key="XXXX-XXXX-XXXX-XXXX",
    hardware_id=hardware_id,
    product_name="MyProduct"
)

validate_offline(offline_code, hardware_id) -> OfflineValidationResult

Validate an offline activation code locally (requires offline_public_key).

options = ExisOneClientOptions(
    base_url="https://www.exisone.com",
    access_token="your-token",
    offline_public_key="""-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8A...
-----END PUBLIC KEY-----"""
)
client = ExisOneClient(options)

result = client.validate_offline(
    offline_code="ABCD-EFGH-1234-5678-...",
    hardware_id=hardware_id
)

if result.is_valid:
    print(f"Product: {result.product_name}")
    print(f"Expires: {result.expiration_date}")

Environment Variables

Variable	Description
EXISONE_BASEURL	Default base URL if not specified in options

Error Handling

from exisone import ExisOneClient, ExisOneClientOptions
import requests

client = ExisOneClient(options)

try:
    result = client.validate(activation_key, hardware_id)
except requests.HTTPError as e:
    print(f"HTTP error: {e.response.status_code}")
except requests.RequestException as e:
    print(f"Network error: {e}")
