How to updating existing Java Applications

KeySeed

Protector4J will request a random and unique key from the server for every encryption task, and since the key is different for each task, the encrypted jar files obtained from different tasks cannot be used together. Therefore, we provide a KeySeed feature, the same KeySeed will generate the same key, and the jar files encrypted under the same KeySeed can be used together. Currently KeySeed is only available for licensed users.

Updating existing Java Applications

1. Specify a KeySeed when generating the application for the first time

2. Select the war or jar file that needs to be updated and check “Only Encrypt Jar Files”

3. Specify the same KeySeed on the output page

4.Check the output folder and copy the newly generated vlxlib folder to the existing application folder, and you may need to remove the old vlxlib folder first if neccessary.
