Iv'e been looking at the Sandman's tutorial about the "wisp" program!.
I have been trying to find how the magic number is generated but can't find how it's done!.
It seems to write to the registry then reads it back again! I found a loop which seems to be checking the digits but can't see where any cmp instructions!.
Can anyone help!. I haven't been cracking for long but I am more interested how the program fetches the sn. than the crack it's self!.
