keyhunt not good

you should learn to configure it, defaul thread subrange is 32 bits, for small ranges with multiple threads you should lower the N value  with "-n number" if the range is less than 1 Million keys you should use -n 0x10000
where 0x10000 its a 16 bits subrange per thread

Look

If someon knows, I will appreciate.
On KeyHunt, BSGS technique we have

bsgs mode (baby step giant step)
Keyhunt implement the BSGS algorithm to search privatekeys for a known public key.


The input file need to have a list of publickeys compress or uncompress those publickey can be mixed in the same file, one public key per line and any other word followed by an space is ignored example of the file:

you need to know the compressed publickey hex66 to run.
However I don't know how to get this. I tried publichash like
Public Key Hash: 20d45a6a762535700ce9e0b216e31994335db8a5


but I can't run because is not the the public key in the format the BSGS need.
Someone know how to do this?
