License4J version 1.3 is released

License4J is a pure Java library for creating and validating licenses.

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.

The new version contains method to retrieve MAC address, fixed bug with random java.lang.SecurityException and is stronger obfuscated by Allatori Java ObfuscatorLicense4J home page and trial download.
