[Tool] NED - Decryptor for SecureGRF

[Neo-Mind 264]

N.E.D. - Neo Express Decryptor

(suggestions are open for a better name)

 

What is this?

 So you might be wondering if this is really what it says in the title and yes it is. The purpose of this tool is plain and simple.

 If you have a GRF encrypted using SecureGRF and you know the password, you can use this tool to decrypt the GRF to get your original back - comes in handy if you forgot to backup the original.

 

How does it work?

 Download it. Open it. Enter the path of your encrypted GRF in the Input Grf field and select the Output Grf filename (by default it suffixes "_decrypted.grf" to the input grf name). Enter the Password and click on Decrypt and your done.

 

Note: The tool might take a few minutes if your GRF has a large number of files (but I see SecureGRF also taking similar amount of time to encrypt). 

 

Anything else to know?

  I made this tool in a day because I was looking for something interesting to do. It has worked so far for all the GRFs I have tried it with.

So just in case keep a backup. Let me know if you find any bugs.

Excited to try your tool

can you send me one of them with the password you tried.

[Ridley 295]

Nah you got me wrong, I meant I tried to decrypt by myself, without your tool but never had a success. I haven't tried your tool yet but will definitely test it

[Neo-Mind 264]

Ah ok.

Hi Neo, will it affect the patch process if my grf is secured?

[Ridley 295]

not sure if i fully understood your question. the patch process it saved in your (severname) .dat and not int he grf

 

and files added to the grf will ofc not be deleted o-o

Now make one that encrypts, please XD

 

(The official one doesn't work on Windows 10, it just crashes)

Input file is 518 MB (543,297,029 bytes) but it completes instantly and the output file is only 46 bytes. Any ideas?
