Re: What hash to support next?

Exactly because of the hillariously large keyspace, I've been trying to
look into making pieces very small... Like 8 bytes or so.

It wouldn't be practical, no .. To save space, you would need to make the pieces larger in size, than the SHA1 hash of each piece.

Re: What hash to support next?

By implementing SHA1, you'll also make it possible to actually calculate the file out of a torrent file. A torrent is divided into pieces, each equal in size (Except the last, which is equal to the remainder of the file). A typical piece size is 256 KB. But what if we made a torrent, with pieces 16 ...

Re: LM Implementation

I've read elsewhere about the problems. However, I haven't quite understood it yet.

Ah well, it'll probably be solved at some point.
Elcomsoft do it at 75M/s on GPU, LM.

Re: LM Implementation

Thanks for that ;)

However I might need some help on the C code part. I'm not the best at C (Actually, I work on C# and other .Net stuff)...

LM Implementation

Description: Name: LM - Lan Manager Usage: Microsoft Windows NT logon users passwords over network / locally. Note: LM can take a max of 7 digits. So the trick for longer passwords, is to concat two hashes. Example: Longpa (Len: 6 (Under 7)): Hash: LM("Longpa ") & LM("") Longpass (Len: 8): Hash: LM...

Re: MD5 Cracker

Righty. I just wanted to make sure I wasn't missing anything obvious ;)

Now off to describe LM implementation.

Re: MD5 Cracker

Ah. I see...

So, server / client is not availible for nVidia GPU's?

MD5 Cracker

First of, I like this cracker. It's quite effective :)..

By reading this forum, I get the idea that there is a newer version, than the one on the frontpage: 0.8...
Such things as server / client implementation.

Am I mistaken.. Or .. ?
