How to get bitcoin address related to this private key? or is there's any way get this private key details like balance or addresses?
the private key is a Private Key WIF Compressed, 52 characters base58, and can be used to convert into (compressed or uncompressed) public keys. These pub keys are usually hex codes, and can be converted into bitcoin addresses: 1D2mnuj9qeRAzmw8mjLDciyvqzQiiYZCfE and 1KWvNZB4Gf2Kars88aGR2cedUb81Q6gZKC. There is no easy way I am aware of to do this in bitcoin client.
Looking at the line you provided, the bitcoin address is behind the comment sign (#), and is part of a HD key, which complicates things even more, if I had to explain it. To understand the whole idea behind keys, you may want to read bitcoin.org or the book af Andreas "Mastering Bitcoin" (online available).
Looking then at e.g. blockchain.info, you can provide the addresses or the keys, and see that there is no value.
Hint: never ever (!) use this key again to transfer values. It has been disclosed, and people are only waiting to snipe the values from this address! - me too :-)
using PHP and Bitcoin-PHP library, we can do the following to get Bitcoin address of any private key:
try {
$master = PrivateKeyFactory::fromWif($key);
} catch (\Exception $e) {
echo "Invalid Address";
}
$BitcoinAddress = $master->getPublicKey()->getAddress()->getAddress();
echo $BitcoinAddress;
