Given a bitcoin private key (such as from a dumpprivkey command) code needs to generate the corresponding public key and bitcoin address. The previous examples will show what is needed. I just want a C function:

char *conv_privkey(char *pubkey,char *privkey)

{

char *btc_address = malloc(70);

// calculate pubkey and copy to *pubkey

// calculate btc_address

return(btc_address)

}

So you should use libtom for all the crypto functions you need (libtomcrypt 1.17 from [url removed, login to view]).

Just using standard C (any OS as it is all just standard io).
