Hey all

Ages back PIP posted a Tutorial for Encrypting Files, which works really well

I was wondering IF anyone has built on this and created a DE-Crypter to turn the file back to it's original state?

If you have Please let me know

Cheers

Chris

It's pretty easy to decrypt something that is encrypted given if you know the key that was used to encrypt it in the first place. I posted a tutorial awhile ago on HASHING which is like encryption but cannot be decrypted, only brute hacked basically.

I'll see if I can find an example of encrypting and decryption and get back to you.

Recently I released an App(A simple tool for encrypting and decrypting files)

Or else do you want to know how to decrypt RC4(pips tutorial)?

I think he wants to actually know how to decrypt the code.

Hey

When I saw your and pip's posts, I remembered having posted part of the source to my CryptoNet quite a while back, specifically the encryption/decryption class I was using.

I looked through the forums and found it, so here it is: viewtopic.php?f=71&t=8702

This will allow you to encrypt and decrypt text using the DES algorithm. I tested the free download and it still seems to be working, so hopefully this will help


Edit: If you'd prefer the original tutorial I found on MSDN and on which the encryption/decryption class is based, here it is: http://msdn.microsoft.com/en-us/library/ms172831.aspx

#hungryhounduk Updated my thing with new post it is a general idea if i remembered that would be the way, and should be doable like #smashapps said if you know the encryption method reversing it should be fairly simple. hope it helps : viewtopic.php?f=38&t=7799&p=79409#p79409
