SDK Distribution and Licensing

SDK License

The following SDK license comes with every distribution (License Client, Floating Client, Management SDK) under /META-INF/LICENSE:

LicenseSpring Compiled SDK License Agreement (LCSLA)

Preamble:
This LicenseSpring Compiled SDK License Agreement (LCSLA) governs the use, distribution, and modification of the compiled binaries for the LicenseSpring SDKs. These SDKs, including those for C++, Java, and .NET, are designed to facilitate integration with LicenseSpring’s license management service. By accessing or using the SDK binaries, you agree to the terms and conditions set forth in this agreement.

1. Permissions:

	* You are permitted to use the compiled SDK binaries provided by LicenseSpring solely for the purpose of integrating your products with the LicenseSpring service.
	* You may create derivative works that rely on or incorporate the SDK binaries, provided such derivative works are used exclusively as part of the LicenseSpring service.

2. Distribution:

	* You may distribute software that integrates or incorporates the SDK binaries, provided the software interacts directly with the LicenseSpring service.
	* Distribution of the SDK binaries, in their original or modified form, is only allowed in conjunction with your own software that integrates with LicenseSpring.
	* Distributed versions, including derivative works, may not be:
		* Provided as part of a hosted or cloud-based service that allows others to access the SDK’s functionality without interacting directly with the LicenseSpring service.
		* Integrated into other services that compete with or do not use the LicenseSpring service.

3. Usage Restrictions:

	* The SDK binaries, in their original or modified form, may only be used as part of the LicenseSpring service.
	* You are prohibited from using the SDK binaries independently or as part of any service that does not interact with the LicenseSpring service.

4. Prohibited Actions:
	
	* You may not reverse engineer, decompile, or disassemble the SDK binaries, except as expressly permitted by applicable law.
	* You must not modify, remove, or obscure any license notices, copyright notices, or other proprietary notices from the SDK binaries without permission from Cense Data Inc.

5. Contributions and Feedback:
	
	* By submitting suggestions, improvement ideas, feature requests, or any other feedback ("Contributions"), you grant LicenseSpring a perpetual, worldwide, royalty-free, irrevocable license to use, reproduce, modify, distribute, and incorporate the Contributions into the SDK or any other products or services of LicenseSpring.
	* LicenseSpring retains sole ownership and rights to the SDK binaries and any incorporated Contributions.

6. Termination:
	* Any violation of these terms will result in the automatic termination of your rights under this license.
	* Upon termination, you must cease all use and distribution of the SDK binaries and destroy all copies in your possession.

7. Disclaimer of Warranty and Liability:

	* Permission to use, copy, and/or distribute the SDK binaries for any purpose with or without fee is hereby granted under the conditions outlined above.

	THE SOFTWARE IS PROVIDED "AS IS" AND LICENSESPRING DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

Dependencies

Note that these libraries also make use of other open source libraries - those are not listed here.

SLF4J

The Simple Logging Façade for Java (SLF4J) acts as a straightforward façade or abstraction layer for diverse logging frameworks (such as java.util.logging, logback, log4j). This empowers users to integrate their preferred logging framework during deployment. This integration permits end users to tailor the SDK's logging to their specific requirements.

Feign

We employ Netflix's OpenFeign library to interact with the remote HTTP server. Additionally, we utilize the bundled OkHttp3 client, included with the OpenFeign library, contributing to cleaner and more organized code.

Gson

Utilizing Google's JSON serializer, the Java SDK maintains uniform naming within Java classes while adhering to the server-side snake-case JSON convention. This approach ensures efficient data compatibility between the SDK and server components.

BouncyCastle

Bouncy Castle, an open-source cryptography library, plays a pivotal role in ensuring secure communication with LicenseSpring servers. This involves comprehensive utilization for generating and verifying signatures, contributing to a secure and reliable data exchange.

OSHI

OSHI, which stands for Operating System and Hardware Information, is a versatile cross-platform library employed for acquiring essential system information. With OSHI, you can retrieve comprehensive data regarding operating systems and hardware components, enhancing your understanding of system configurations.

Lombok

Lombok is a convenient library designed to eliminate repetitive boilerplate code in Java. It generates getters, setters, and the builder pattern, simplifying the creation of value objects (immutable structures). By offering a neat and intuitive interface for API interaction, Lombok enhances the SDK user experience. It's important to note that the library dependency isn't included in the final output binaries.

Versions currently being used in latest SDK:

<gson.version>2.11.0</gson.version>
<slf4j.version>1.7.30</slf4j.version>
<lombok.version>1.18.20</lombok.version>
<feign.version>13.1</feign.version>
<bouncycastle>1.78</bouncycastle>
<oshi-version>6.6.0</oshi-version>

Dependency Licenses

Aggregated Licenses from open source dependencies present within the LicenseSpring Java SDKS. Please note that any dependency that contains the GPL/LGPL license, also has an Apache 2.0 license attached, so the GPL/LGPL licenses can be ignored.

They are also included in the .jar under /META-INF/DEPENDENCIES_LICENSES.txt
