Introducing License4J, the ultimate licensing and protection software for Windows 7. Developed by Smardec, this innovative software allows developers to easily create and manage license files, cryptographically secure their application, and much more. With a user-friendly interface and robust features, License4J is the ideal choice for any software developer looking to secure their intellectual property. Try it today and take your application security to the next level.

The key concept is features of a license. You can easily add any feature to your license file, i.e. name of the product, version, expiry date, number of executable instances, customer's name, company, IP address, etc. The feature's value can be string or any serializable Java object. You can have unsigned features - features that are not used in the signature generation/verification and therefore can change their values leaving the license valid.

Also the library provides methods for signing arbitrary content that should not be changed by the user.

For the maximum protection of your application it is highly recommended to use Allatori Java Obfuscator together with the License4J library.
