[TuT]Making a Bruteforcer 03-18-2011, 09:11 PM

Hi!!!
Today you will (hopefully) learn how to make a bruteforcer in VB.NET
Its pretty simple once you get the system
WARNING: VB.NET ISN'T a good language for bruteforcers since its slow, it will take ages to break more complex passes. Use C for some serious job
So, lets start
to prevent leachers, Ill make a console app that will just print the letters, but its pretty easy to make it into working bruteforcer
The code:
Okay, so what does what:
Public declarations, they can be private... I like them public, in case I need them somewhere else
This sets an variable "first" as an integer. The variable has assigned a number: 97 for beginning, then it executes the code and moves to next number, this is repeated untill the number is 122, then in moves to next code, in our case another loop With the next loop, this one starts again.... and thats how the bruteforcing works
"Chr" is an ASCII character code, where the number in the brackets is the character number, Asc() does exactly the oposite
Ok, now you should get the idea how it works, if you have any problem, just post it here =)

Spoiler:
Code:
Sub Bruteforce()
'CheckForIllegalCrossThreadCalls = False 'For MultiThreading
For eigth As Byte = 97 To 122
For seventh As Byte = 97 To 122
For sixth As Byte = 97 To 122
For fifth As Byte = 97 To 122
For fourth As Byte = 97 To 122
For third As Byte = 97 To 122
For second As Byte = 97 To 122
For first As Byte = 97 To 122
TextBox2.Text = Chr(first) & Chr(second) & Chr(third) & Chr(fourth) & Chr(fifth) & Chr(sixth) & Chr(seventh) & Chr(eigth)
Next first
Next second
Next third
Next fourth
Next fifth
Next sixth
Next seventh
Next eigth

This loop idea came from my friend when he needed a quick bruteforcer and he got the idea while watching a clock
