Hi KKR_WE_RULE,

With respect to your software, there are names which result in a very simple keys: I tried (as a german)
"Mein Name ist Hasen"
This results, e.g. in a key of 5-7.

Even more, if I try
"Mein Name ist Hase", your compare value yields 0 (and my keygen (currently being reviewed) fails. Intended behaviour?

I tried to implemention of a Conjecture.

If ya know whats happening inside kgm, ya should know which conjecture is it :)

Not all names have serial .. I suppose :)

Yes, I think I know which reject condition you mean.
And with respect of not all names having a serial - never mind, perhaps would have been worth to leave a note in the challenges' description.

Sorry for inconvenience josh :(
I am a beginnner in asm.

I am sure that I was able to implement the Conjecture perfectly, but probably the checksum is bit buggy :(

Sry for that :(

The key for "Mein Name ist Hasen" = 11-1

There is more than one valid key for a name.

@BondCracked
You mean "Another key for "Mein Name ist Hasen" = 11-1", because, as you state correctly, there are many keys for one name.
Therefore, I gave my key of 5-7 as "e.g".

Yes, Josh, you're right. Did you coded a keygen?
josh
11. Oct 2010
Yes, I submitted it as binary. Source is available too, if necessary. Did you?

Yes, I did too, but my English is not strong enough to write a tutorial. I'm waiting to read yours.
