yeah right I just cleaned up the thing that was looking some complex.

Nothing just converted into macro.

Bit slice concept I got. Well, I was I testing the case of block
initialization as you told me in previous posts. But problem is not there.
Real problem lies here. Copy test vectors in this way :

$ cat pw
$ cat w

Run it. Now it will crack the passwords.

So problem lies in mismatch of index numbers of cipher text and key that is
not with any other case of bit slice format. If you have remedy to this
problem then you can tell me other wise I am working on it. It is not so
big problem but may take some time as now I have to scratch the cracker. c
file. Oracle format is so nice :-)

Well, I want to help the project but with out learning I can't do it. so
you can say both :-)

Thanks for this mercy on me :-)
