But to continue my research I need to know one or two private keys of 10 million Bitcoin addresses.
Yes, I generated these Bitcoin Addresses through certain numerical coordinates. Then I translated these numbers into the HEX format and received Public Keys. (Further Standard Base58 (SHA256 (ripemd160)))
so you started with numbers then translated into the
HEX format then public keys... right?
isn't that
HEX format what we called
"Private Key Hexadecimal Format" 64 chars?
then if you have this
Private Key Hex you can find its
Private Key WIF (cmiiw)
so... what do you mean by "you need to know"? you already knew their private keys from the start
