Hi!
I have a software developed in ASP. I want to sell it in encrypted form so no one can edit.
I have seen that type of encryption in toastforums.com which IIS server decrypt automatically.

Anyone has any idea about how to encrypt classic asp code files for code security.

Thanks in advance for help.

There isn't such a thing. If the server can decode it so can anyone else. It's only a matter of effort and time.

The MS Script Encoder (screnc.exe) which Toast have used hasn't ever been "secure" from anyone other than casual "onlookers"

Use it by all means but it will not stop your source being "stolen"

The only way to make ASP code 100% secure is to compile it into ISAPI DLL modules and require it to be installed and registered on the server. Your script then simply become a series of calls to properties and methods in the libraries.

Hello Ariese,

I understand your problem. A couple of years back i developed a real estate software to list real estate listings and put it on sale. After some time I found that most of my customers are software developers who purchase my software and after few adjustments put it on sale from there web site.

Also many of developers purchased only one license, which is for one web site only, and used the same single license for more than one clients. Which is a clear breach of license policy.


Now I have developed advance version of real estate software and put some important functions into a single file and encrypted that ASP file using Document Encryption Software available at Protware.com.

No one can decode that ASP file. I put some codes in that file that let me know the Software Key, Client Name, Order Number and other necessary info and if someone breach license policy, I can even block that web site.


So Protware.com has the solution to encrypt ASP, PHP, Javascript files...

Thanks chrishirst!

This is the exact software which I needed.
