How to update an existing encrypted Java application


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

Update existing Java applications

1. When generating the application for the first time, specify a KeySeed

2. Select the war or jar files that need to be updated and check "Only Encrypt Jar Files"

3. Specify the same KeySeed on the output page.

4. View the output folder and copy the newly generated vlxlib folder into the existing application folder. If necessary, you may need to delete the old vlxlib folder first.
