Description:
I am looking for a commandline or webbased PERL or Shell script or what ever you suggest which can encrypt the Perl Source Code so that it will be very hard for people to steal , I sell my scripts and I am looking for some one who can make me very good 100% secure solution in order to encrypt, obsfucate .pl , .cgi or .pm files

The software will easily encrypt the whole directory , and then output the file to other directory , we are using MD5 to create license key manually so I will provide you that in order to send users to EXPIRED page once the script date is expired.

Let say once we encrypt the software I want that encrypted code to execute normally in all browser just like normal scripts.

But when i sell the code to some one they cannot see what was there in the code it will be like the following it was just an example I give

#!/usr/bin/perl
343$#$#%#$%$%$%

I hope you all understand what exactly I want.

Also once you people completed the software, I will be having FULL copyrights to the software.

Thanks

Hallo,
I want you to be aware that there is no such thing as 100% protection. The encryption should be reversible or the perl compiler will not be able to process it. And if it is reversible a really good programmer will be able to steal it.

Anyway, I've done such protection before and it does pretty good job. There are 3 levels of encryption. First, it randomizes the variables and procedure names so that you'll never be able to get the idea how it does what it does. The other 2 levels are 2 different custom methods of 2-way encryption along with CRC check. The CRC check ensures that the script will stop working if they change even a bit of it.

Let me know if you're interested.

Have a nice day!
