Of course it's not hard at all Smile

Check out the tutorial at www.madwizard.org - it is one great tutorial!

It helped me a lot. Smile

People need to learn to code before actually trying to reverse. It is a great help!

Start by learning how to program in ASM. It will take much time, but you'll eventually figure that it is all wort ...

Copy and paste it in notepad. Replace every '0x' with a '0', and after replace every ',' with a 'h,'. Voila, you're done =)

What about it? It'll have included a 3D version of Solitaire.

Hehe, just kidding. Just another obsolete OS by M$. That's all Wink

I think numbers doesn't matter, skills matter.

Numbers are everything (and operations :p).

I've played with this kind of stuff on my previous box (it was WINLOGON for me though, 2K). Anyway, you can try attaching to the file while the Windows is already running. I cannot guarantee you that ...

If the md5 check up passes, just use the password that the user entered as a decryption.

EDIT: As simple as:

Encryption:

1) User locks notepad.exe with password "helloworld"
2) Your program ...

You could use something like MD5 checksum. A small (and working) example:

User protects a file using password "test123", take md5 of that:
4a251a2ef9bbf4ccc35f97aba2c9cbda

Store that key in the ...

Ah, this program's password feature is not very safe (XOR). It is very easy to reverse. Let's try a small example.

Copy calc.exe from your Windows folder to Desktop, and password protect it with PE ...

I already had that in my code.

if (!(y%4)) days++;

If that's what you meant Wink

/*
* This program calculates the difference (in days) between 2 dates.

* Example:

* Date1: 01 01 2002
* Date2: 01 01 2003

* Would return 365 days.

One way is to disable the CRC check. Another way is to use debug APIs, that way you can change the value of any register Wink

UPDATE: Yes, you were right. Smile

Damn MASM somehow added wsprintf for nothing. This is what my code assembled to:

00401000 >/$ 68 00304000 PUSH boro.00403000 ; /FileName ...
