Hide javascript from client? i think i've done it!

[Nelson Campos]

Hello all,

I belive i found a way to hide javascript from the client.. i use php.. page referral and sessions to restrict access, run the code and then run a fake code to clean the script file.

I've already done some tests and didn't found a way to view the javascript code.

if anyone want's to give it a try, i made a testpage just for that purpose: http://prtg.eu/lockedscript/testpage/

on the scriptfile i have a line that says:

// Here is the code you need to proof you where here --> ######

if you can view the script, tell me that code and how did you found your way around the protection to view the script.

FireBug > Script > lockedscript.php

[Nelson Campos]

any particular configuration on firebug? i have firebug too and it doesn't show the script..

[Dormilich]

probably a combination of previously inactivated Javascript, empty cache, first visit and luck.

i found some problems in the session vars wich are not working has supposed.. for the moment any tests made on the website might not work.. when i correct that ill post here again ather implement better security

[Nelson Campos]

new security setting have been implemented, including a bug that has been solved on IE..

Dormilich: would you like to try and mimic that last shoot?

everyone else can try access the javascript file and tell how and give the new proof code
