btc_address_generator

A simple script for generating BTC addresses, for creating offline wallets

Requirements

The current implementation requires the php gmp extension. Future version will automaticly detect and switch between GMP and BCMATH

Usage

Download files.

BTC address generator:

require(__DIR__ . '/../classes.php');
function microtime_float() {return microtime(true);}

$t1 = microtime_float();
echo "Start time: $t1 sec \r\n";
$str = '';
for($a=1;$a<=1000;$a++) {
  $private = new PrivateKey();
  $wallet = new Wallet($private);
  $key=$private->getPrivateKey();
  $private_key=AddressCodec::WIF($key,'80',true,false);
  $deWif=AddressCodec::DeWIF($private_key,true,false);
  $addr=$wallet->getAddress();
  //echo "$addr,$private_key<br>\r\n";
  $str.=$a.',"'.$addr.'","'.$private_key.'"'."\r\n";
}
$t2 = microtime_float();
$time = $t2 - $t1;
$fname_addres = 'address_'.time().'.csv';
echo "End time: $t2 sec \r\n";
echo "Elapsed time: $time sec \r\n";
file_put_contents($fname_addres,$str);
echo "Saved the file: $fname_addres \r\n";

BTC get info

require(__DIR__ . '/../classes.php');

$addr = '17sGrxMRs9Mm3nzk4jhMyiN3HJ4o8aenqk';
$getInfo = new GetInfo($addr);

$fname_save = 'addressbalance_'.$addr.'.txt';
$info = $getInfo->blockchain_info_addressbalance($addr);
if ($info === false) {echo "Error: {$getInfo->last_error} \r\n";}
else {
  //echo '<pre>';print_r($info);echo '</pre>';
  file_put_contents($fname_save,$info);
  echo "Saved the file: $fname_save \r\n";
}

$fname_save = 'rawaddr_'.$addr.'.txt';
$info = $getInfo->blockchain_info_rawaddr($addr);
if ($info==false) {echo "Error: {$getInfo->last_error} \r\n";}
else {
  //echo '<pre>';print_r($info);echo '</pre>';
  file_put_contents($fname_save,print_r($info,true));
  echo "Saved the file: $fname_save \r\n";
}
