Overview

Example Java Cryptographic License Files

This is an example of how to verify and decrypt cryptographic license files in Java 18 using Bouncy Castle.

This example verifies the aes-256-gcm+ed25519 algorithm.

Running the example

First, install dependencies with mvn:

mvn compile

Then run the program:

mvn exec:java -Dexec.mainClass=sh.keygen.example.Main

You should see log output indicating the current license file is valid:

License file signature is valid!
License file was successfully decrypted!
