    Serial/Licensing system

    Hi all I've made a simple serial and licensing system (although we know we already lost the war against the crackers... mainly using AU3 with too many decompilers available for free). That's not as you're accustomed to see outside, but that's interesting (I think). That's how it works: There aren't automatic demonstration licenses. After installing, the software won't work (truly, it will ask for a serial). The client must contact you/your company in order to get a free demo key or buy a full key. Yeah... the serial keys are quite big. That's made to copy and paste from the email sent from you to the client. It's the result of some informations encrypted, like how many days the serial key will work, a limit day to register using that serial (after that day, it won't be possible to register using that serial (if the user registered before, the license will still valid. Don't worry)). The user ID that is used to generate the serial key isn't an user input, like his email. It's generated based in some computers informations, like CPU/OS Architecture and others. The user must sent this key to you, and you'll send back his serial. But unfortunally I couldn't find a better way to save the license info. Actually, I'm using a file in %APPDATA% (encrypted and unreadable to look like compiled or a structure file, of course). If this file is changed or deleted, the application won't work and will require reinstallation. The file below brings some examples and the UDF (very well commented... I guess). It's very easy to use. It has also a KeyGen to generate and validate your serials. You'll need >Melba23's Extended Message Box UDF. Just download it and copy ExtMsgBox.au3 and StringSize.au3 from his UDF to the same folder with "license.au3" from my script. Or it won't work. Download: license.zip

  2. There are jQuery events attached to the element. You will need to trigger the Change event via jQuery. I'll get back to you if I come up with a workable solution.

  3. The site is likely using a Javscript framework, such as Node.js or React. These will obscure the code, use hidden objects, etc like you are seeing. This is probably going to be difficult for us to assist you with since the site is private. First step would be to identify the framework being used.

  4. @czardas & @jchd: Ladies, aren't we getting a bit off-topic here? @Belini: I fear your quest is completely futile. If it's on screen, it can be copied. Never heard of screen recording software?

  5. I'm not surprised your PC needs more Sleep after doing all that lot at the same time.
