hi guys this is my first
password protect system and i want to test it. I'm not very good at cracking passwords so I'm asking for your help.
What you have to do:
Simple, crack the password by any means
if you try to crack it directly you will only have 20 seconds to introduce the wright password.
Ho to prove that you cracked it:
a message will be shown, just write here what the message says.

Maybe he just used binary. Like having something, like a label, with some binary data. Then set that password from that data, just in a string. When you press the GO button it checks if the textbox's text is the same as the password. But that would be too easy to crack, Im sure its many ways to get that binary data.
Im sure he used another way

I didn't get the password as it seemed like more effort than it was worth.
I used a hex editor to list the strings in the file and noticed one of them was a Regex command; by patching this to something invalid it caused an exception at the form load and then stopped the password from being generated properly.
Also I changed the label timer text by changing its value in memory.
