Code obfuscation ? Studies with limited validity ?

[Spin]

Hi there fellow (commercial) programmers !

I was wondering what methods you use to protect your well-written and hard-earned code from reverse engineering & non-legal copying.

I looked into 'good old' ProGuard, but it seems it's only good for code up to Java 10, and the latest mwave_sdk.jar is 11. So that won't work anymore...

Second (related) question: how do you make a Study only ' usable' for a set period of time (e.g.: clients buy it but can only use it for a year, after that they need to renew their license)

Thanks for your input !

You may want to setup your web service, http based, and check a study license. You would keep track of your clients and enable/disable the study functionality. Just a thought.

cheers.

Hi @igor.s ! Thanks for your reply, that does indeed sound like a good suggestion.

Digging a little deeper: no one has had any luck with obfuscating code that uses the latest "mwave_sdk.jar" ? (A newer version was recently posted by the MW-crew)
