Start
0000000000000000000000000000000000000000000000040000000000000000

End
000000000000000000000000000000000000000000000007ffffffffffffffff

Can someone help in creating BAT file for cubitcrack?

Hi,
For the range for 67 bit add this:
--keyspace 0x40000000000000000:0x80000000000000000 1BY8GQbnueYofwSuFAT3USAhGjPrkxDdW9

THANKYOU MAN!
last question
will the brute force attack will be random or sequential, if sequential than how can we make attack random. Since I believe random attack has more chance for success.

[ZainGTR]

BitCrack is sequential like most GPU tools, if you want to add randomization, I recommend you implement a later that sends the job to bitCrack.

You can use the stride option. Or there is a modified version with random option -> https://github.com/djmuratb/BitCrack2

thanx man!

in modified version how should I create the bat file if I want to target puzzle 67 randomly?

[marssystems]

BitCrack.exe -b 64 -t 256 -p 1024 --rstride 5 --keyspace 40000000000000000:7ffffffffffffffff 1BY8GQbnueYofwSuFAT3USAhGjPrkxDdW9

If we want to target this address
1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF
In random mode
How should we create the bat file?

Use the -r argument. Anyone has idea if Bitcrack supports vanity search? I have lost the original brichard link of the full bitcrack functions... Thanks.
