Fireclipse, and encryption program by me
    #14447937 - 05/13/11 09:02 PM (12 years, 9 months ago)

Get it here: https://rapidshare.com/files/727865999/Encryption.zip

If you would like to protect individual files and keep them from prying eyes, this is what you're looking for!

I wrote this program myself. It's very strong encryption, and features an optional on-screen keyboard to fool keyloggers that would steal your password. I've tested it on Windows XP Sp2 and Sp3.

If you forget the password, don't bother asking me for it, this software has no back-doors! I can't recover your key either.

Once you select a file, and then enter a password, it will display the hashed version of the password, and the hashed password length in a message box (just for your information, no need to remember this info). When the output box says "Encryption Finished!" the operation is complete.

On my Pentium D, it takes about 20 seconds to encrypt a 1MB file, and about 35 seconds to decrypt that file.

There is a "Backup" button in the bottom left corner, USE IT until you understand how the program works.

Test the program out with a notepad file you don't need first.

A Help File is included.

What kind of encryption?  What kind of algorithm did you use?  Did you write the algorithm yourself?  What did you base it on?  In what language?  How secure is it?

You can't honestly expect people to use it without some more details, my friend.

TwoFish Encryption (256-bit)

...and no you can't have the source code :smile:

Why did you laugh? It's pretty strong encryption.

You don't honestly expect anyone to use your closed source encryption program...what proof can you give that it actually works? Or that it isn't full of back doors? Why not release the source, in any case? Unless you are trying to hide something...

If you forget the password, don't bother asking me for it, this software has no back-doors! I can't recover your key either.

The very fact that you said this leads me to believe you are trying to con us. Nice try.

I'll use your program as soon as you release the source code.

This was compiled with VB6 Pro, and it needs Comdlg32.ocx, which is a microsoft file.

It isn't just "here".  Peer review is mandatory for any encryption system to be trusted.

I haven't looked at your code, but I am curious if you zero out any allocated memory before releasing it back to the OS.  This is especially important with any allocated memory that holds the encryption key.  Remember, automatic variables (usually held on the stack) must also be cleared before a function returns.  Failure to do this creates a huge security hole.  Anybody with access to the running system can create a copy of all dirty memory pages, which could include the password.  Even if the system has been rebooted, the page file may also contain a copy of the password.  There are other tricks, such as splitting data up on to multiple pages of memory rather than storing it contiguously.

Writing an encryption program might be fun, but no one else is ever going to use it.  Why wouldn't we all just use GPG, or TrueCrypt?

I haven't looked at your code, but I am curious if you zero out any allocated memory before releasing it back to the OS.

Or taken steps to prevent another process from peeking into your inter-thread shared memory. Or if you write any of your state to the file system, it should go without saying that you can't just delete the file when you're done; you have to securely overwrite it too. How about clobbering the Windows internal keyboard queue where the password will live for a while, possibly well after your process terminates?

How do you generate entropy? If you're not using a true random number generator based on some physical process, like radioactive decay or avalanche noise, might it be vulnerable to attack? Without wide peer review, we have only your word that it's free of vulnerabilities.

Writing encryption software isn't just about correctly implementing the algorithm (though that's important too), it's also about a zillion little details that can and will be exploited if the software comes into wide spread use.

These things bite Microsoft on the ass on a regular basis, and they have PhD mathematicians and computer scientists by the thousands looking over their code. How much more likely is it that you made some tiny mistake that renders your system vulnerable?

Nothing personal here. Just telling you how the cryptography real-world works.

It was a fun project that I wanted to share with everyone. I know there's tons of good products out there that offer some nice features, too. Mine does avoid keyloggers and doesn't require installation, and is free.

If you're curious on how the program works as far as zero'ing the memory, take a look at the .cls files for your answers.

And yes, it was tons of fun writing it! :smile:

I bet it was fun, I am still very, very novice in my programming skills.  The only thing I know is some C++ but I keep learning more everyday.

I wrote 13 visual basic 6 tutorials several years ago. If you get your hands on a copy of either Visual Basic 6 or Visual Studio 6, I'd be happy to email them to you in a zip file. I think I still have a copy of "The Visual Basic Black Book" as well, and it's a great resource. Do  you want that as well?

Since they're relatively outdated now, as Visual Studio is in a much newer .NET version, it's sort of pointless to post them here, right?

OP was pretty naive to not post his source to begin with.

That said, I was able to extract from the archive fine.  I found that OP did not implement any algos himself, which is the most common mistake among newb cryptographers.  The biggest mistake he made IMO is it's way too complicated overall.  I didn't fire it up, but as the OP describes it sounds like a simple asymmetric process to make store confidential data; AES should perfectly adequate on its own.

Actually, I've wrote several programs of this type, and they've all been open source.

I can't wrote those algo's, I used standardized methods.

Which part was too complicated? The compression, then encryption, then encryption part?

Dimi-- I meant you *didn't* make the common mistake of reimplementing the algos.  By too complicated, I meant How does your use of 4 different algorithms provide a better solution than using AES alone?

I understand your message now :smile:

I think, by the way my implementation works, only my software, or the use of my modules in that specific order will open files created by the software.

One algo is huffman compression to shrink the encrypted file size and provide a little speed boost,  it does work on most non-compressed files.

The next two are AES and TwoFish.

The fourth algo isn't used, I forgot to remove it from the file list when I zipped it :smile:
