hi
in script, there is bug, or maybe he unable to catch point, as
if you have 37 bit pubkey
and you command is
./script 40 02xxxxxxpublickey
40 bit mean search in bit range
but script will find key in 37 bit
if you have 42 bit key, and same command for search in 40 bit by apply 40 or 8:fffff.... bit range, script will find 42 key

its not restrict only for define bit range
mean always find start from 8 to onword, so its take time consume, Smiley
test it

Yes, this was my point.
I first thought that there is a parallel behaviour, cause the script was finding the publickey when changing y value only, and we could use it to only make sqr(2^(bit-2)) operations,
unitil i found a completely different pubkey from another space.
You don't have to set from 8:... bitspace it also works with orginal keyspace

It's not a bug i guess...i am cleary not an expert in this matter Tongue

, but that's what i think:
It seems logical, it will just take longer on average to find the key.
The average jumpsize should be calculated from the searchspace.
When you search for exampe puplic key from 37 bit within 40 bit the average jumpsize should be bigger and the opposite when searching 43bit pubkey within 40 bit.

It's strange, that when you change only the y value of the key, you will find the orginal publickey with privatekey, but not the one you changed.
