FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package php-sdk

KeyManager - PHP SDK

Version: 3.0.0 - Identifier-first architecture with offline-first validation!

Features

Core Features (v1.x)

✅ License validation (online and offline)
✅ License activation and deactivation
✅ Feature flag checking
✅ Hardware ID generation
✅ Telemetry submission
✅ RSA-4096-SHA256 signature verification
✅ Automatic retry with exponential backoff
✅ Built-in caching
✅ Idempotent operations
✅ PSR-12 compliant

New in v2.0.0

✅ Complete license management - Create, update, delete, list licenses
✅ License assignment - Assign licenses to customers (sync & async)
✅ Metadata management - Custom metadata for licenses and products
✅ Product management - Create and manage products via API
✅ Generator support - Generate licenses programmatically
✅ Contract management - Manage API contracts
✅ Downloadables access - Provide downloadable files to users
✅ Advanced telemetry - Retrieve telemetry data with filters
✅ Public changelog API - Access changelogs without authentication

New in v2.1.0

✅ New endpoints: getLicenseFile(), getProductMeta(), getProduct(), getProductChangelog(), getProductPublicKey()
✅ New response codes: LICENSE_FILE_RETRIEVED (502), LICENSE_FILE_GENERATION_FAILED (503), LICENSE_KEY_NOT_FOUND_DETAILS (501), PRODUCT_FOUND (631), PRODUCT_PUBLIC_KEY_FOUND (632), PRODUCT_PUBLIC_KEY_NOT_FOUND (633)
✅ Offline .lic parsing: parseLicenseFile() (Base64 decode → 256-byte chunks → RSA PKCS1 decrypt → JSON)
✅ License/key sync: syncLicenseAndKey() with atomic file updates + telemetry
✅ Validation timers: isCheckIntervalPast() and isForceValidationPast() (fail-safe true on error)

New in v3.0.0 - BREAKING CHANGES

✅ Mandatory Identifier Parameter - All validation/activation methods now require $identifier (domain or HWID)
✅ Configuration Inheritance - Set productPublicKey, licenseKey, licenseFilePath, defaultIdentifier once, reuse everywhere
✅ Offline-First Validation - Try cached .lic file first, fallback to API with ValidationType constants
✅ Type-Safe DTOs - ValidationResultDto, ActivationResultDto, SyncResultDto with typed accessors
✅ Constants & Enums - ValidationType, IdentifierType, OptionKeys for predictable behavior
✅ Helper Methods - generateIdentifier(), getIdentifierOrGenerate(), resolvePublicKey(), canValidateOffline()
✅ Enhanced Error Messages - Actionable, context-aware errors with documentation links
⚠️ ⚠️ MIGRATION REQUIRED: See Migration Guide v2→v3 below

Offline .lic Parsing (LicenseValidator)

Force Validation Check

30+ new methods added while maintaining full backward compatibility!

Requirements

PHP 7.4 or higher
ext-json
ext-openssl
ext-curl

Installation

Via Composer (Recommended)

Manual Installation

Download the SDK files
Include the autoloader:

Quick Start

Initialize the Client

Validate a License (Online)

Activate a License

Deactivate a License

Check Feature Flags

Validate Offline License

Send Telemetry

Generate Hardware ID

Configuration Options

Option	Type	Default	Description
`apiKey`	string	required	Your API key
`publicKey`	string	null	RSA public key for signature verification
`baseUrl`	string	`https://api.getkeymanager.com`	API base URL
`timeout`	int	30	Request timeout in seconds
`verifySignatures`	bool	true	Verify response signatures

`retryDelay`	int	1000	Retry delay in milliseconds

Error Handling

The SDK uses a hierarchy of exceptions:

Example Error Handling

Caching

The SDK automatically caches:

License validation responses
Feature flag checks

Clear Cache

Signature Verification

All API responses are cryptographically signed. The SDK automatically verifies signatures when verifySignatures is enabled.

Using SignatureVerifier Directly

Verify JSON Response

Idempotency

Activation and deactivation operations support idempotency:

Best Practices

1. Store API Key Securely

2. Cache Hardware ID

3. Handle Network Failures Gracefully

4. Validate Licenses Periodically

Testing

Examples

See the /examples directory for complete working examples:

validate.php - Basic license validation
activate.php - License activation
features.php - Feature flag checking
offline.php - Offline license validation
telemetry.php - Sending telemetry data
