1.a file named KEYFOUNDKEYFOUND.txt will be generated in the root of the keyhunt folder
2.in BSGS mode (after it was discovered by others) I found the private key for #64 in 14 minutes, but you can try in rmd160 mode and see what keyfound knows, using the command "./keyhunt -m rmd160 -f tests/1to32.rmd -r 1:FFFFFFFF -l compress -s 5", to convince yourself.
After testing, you choose your own method of use. If you have a PC with at least 64 GB RAM, you can choose the factor -K 4096 and reach 10 Petakeys/second or more in BSGS mode.
