How to protect scripts?

Hello,

I'm doing some scripts that I want to sell, but I want to protect them before release.
Is there any way to protect scripts?
For example, how to block them if the "license key/code" is not-valid.

Thank you in advance.

 

You can use a code obfuscator if isn't compiled. If the script is in php you can use github.com/facebook/hiphop-php/wiki/ but it generate c++ code that you can compile(fro example with gcc).

 

Hello,

I's a php script, I want to sell it and have it protected to avoid nulled versions, I know it's impossible to protect completely but I want to protect it most possible.

 

the simpliest way is an obfuscator search on google for PHP CODE OBFUSCATOR

 

Obfuscator just "hide" the code right?
Do you know something to protect with activation key/code?

 

Yes, the obfuscator "hide" the code. I think is impossible use an activation key.

 

you can use javascript languge to add your protect code for the copyright

 

You can also give a try to free online obfuscator for php 4.xx
