Anyway to decode or encode the script back to original?

Thanks in advance!!!

 

[Peter]

looking at it quickly it looks to be base 64 encoded (hence the base64_decode call)

Try running the source through base64_decode.

I tried to Decode using this method...it is not working...any idea?
<?php
$str = 'JE8wMDBPME8wMD1mb3BlbigkT 09PME8wTzAwLCdyYicpO3doaWxlKC0tJE8wME8wME8wMClmZ2V 0

echo base64_decode($str);
?>

either the line breaks messed it up or something else...cuz its an invalid base64 string

"Reverse engineering of this file is strictly prohibited."

Why are you ignoring this?

P.S. You'd have to base64_decode it multiple times (sometimes 100+), that's how the security is generated.

 

[newsiness]

I understand that it is prohibited...
I am taking this as a challenge to decode this script...of coz I am not using the script after it had been decoded...

Really appreciate if someone could share with me the best way to decode this...:P Thanks

P.S. I tried this site http://makcoder.sourceforge.net/demo/base64.php to decode it, but it is not working...

Was this file generated by Zend encoder or similar ?

 

[Peter]

Unless I am very much mistaken sdsinc Zend encoder does not use base64 encded source code.

 

[newsiness]

Tried Zend Encoder...not working...

it would be more of a challenge if you figured it out yourself by learning about encoding, rather than simply asking people on forums don't you think?

 

[newsiness]

I have spent nearly a month but still can't figure it out...

This file is generated by phpLockIT

But I think reverse engineering it is not that easy.

The key itself is encoded in the file itself. So maybe brute force attack will do.

Have u tried this

Example#1 base64_decode() example
<?php
$str = 'VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZw==';
echo base64_decode($str);
?> 

The above example will output:
This is an encoded string

 

[Peter]

yuvanextgen how on earth would that help him to decode the script?

 

[Sakura]

Send me a PM of this file, I may be able to assist, but I will not be resposible for your actions.
