so i was looking at this script ethercheck
and i gave it a private key...some crap i came out with
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364144
and to my surprize it came out with and address
0x6813eb9362372eef6200f3b1dbc3f819671cba69
everything else seems to work fine. any ideea on why it works with this?
no address at all, an error
LE: so my question is why does it generate and actual address if the private key is invalid?
