Hello once again

 

Here is a quick KeygenME i put together for newbies in keygenning.

 

I know most people will solve this under 5 minutes.

 

Rules

 

No rules.

 

Solutions

 

A working keygen that can generate more than one key per name : Diamond

 

A working keygen that can generate one key per name : Gold

 

A valid name serial combo : Silver

 

Patching : Bronze

 

A Tutorial would be appreciated.Please Do Solve.

 

Thanks.

After a preliminary look, I've deduced the following:

• Name length x s.t. 3 <= x <= 32 && x is odd
  
• Serial length >= 26
  
• Activation code length > 0
  
• The serial has hyphens at positions 5, 10, 15, and 20
  
• First part of serial is uppercase Latin alphabetic
  
• Second part of serial is lowercase Latin alphabetic
  
• Third part of serial is special characters: !@#$%^*()+|\<>?/=:;
  
• Fourth part of serial is numeric [0..9]
  

I won't spoil the rest.

 

I'll give it another look when I have more time. I hate reversing Delphi stuff, but it seems interesting. Who knows? I might even put together a tutorial.

 

Cheers.

 

 

Edit: Here's a lazy patch job.

Does that sound right so far?

That was quick.

Nice one.

As for reversing Delphi stuffs, here is a little secret, i hate it too.

Looks like I beat ChOoKi to the punch on this one.

 

It was fun. Thanks for the diversion! Looks like I get all the prizes on this one.

 

Keygen attached.

Hi,

Thanks for solving but there is a bug with your keygen.

if length(username) = 29 then your keygen crashes, if length(username) > 29 and isOdd(length(username))

then it generates incorrect keys.

 

please do check this out.

 

Thanks Once Again, and its pretty nice you beat ChOoKi to the punch on this one.

if length(username) = 29 then your keygen crashes, if length(username) > 29 and isOdd(length(username))

then it generates incorrect keys.

 

I noticed this after I uploaded it. I know how to fix it, but I'm feeling really lazy right now.

 

It's what I get for trying to be clever.

 

Original post has the fixed version.

Rub it in guys, rub it in !

@Office Jesus: Don't forget the tutorial buddy.

A Tutorial would be appreciated.

 

It took two weeks, but it's finally here as promised:

Note: I forgot to include the full stop (2Eh) in the array of special characters. It works regardless. Maybe that's just my way of "watermarking" my solution. Who knows?
