use BitWasp\Bitcoin\Crypto\Random\RandomGenerator;
use BitWasp\Bitcoin\Key\PrivateKeyFactory;
$random = new RandomGenerator();
$privateKey = PrivateKeyFactory::create($random);
2. 从私钥生成公钥
公钥是通过私钥衍生出来的,在有了公钥后,才能生成比特币地址。
$publicKey = $privateKey->getPublicKey();
3. 生成比特币地址
最后,您可以根据所需的地址类型,从公钥生成比特币地址。以下是生成P2PKH格式地址的代码:
use BitWasp\Bitcoin\Address\AddressCreator;
$addressCreator = new AddressCreator();
$address = $addressCreator->fromPublicKey($publicKey);
echo $address->getAddress();
以上过程结合了私钥生成公钥,再根据公钥生成比特币地址,完整的流程简单明了,便于开发者掌握。
#### 代码示例
完整的PHP代码示例
以下是生成比特币地址的完整代码示例:
require_once 'vendor/autoload.php';
use BitWasp\Bitcoin\Crypto\Random\RandomGenerator;
use BitWasp\Bitcoin\Key\PrivateKeyFactory;
use BitWasp\Bitcoin\Address\AddressCreator;
$random = new RandomGenerator();
$privateKey = PrivateKeyFactory::create($random);
$publicKey = $privateKey->getPublicKey();
$addressCreator = new AddressCreator();
$address = $addressCreator->fromPublicKey($publicKey);
echo "Private Key: " . $privateKey->toWif() . PHP_EOL;
echo "Public Key: " . $publicKey . PHP_EOL;
echo "Bitcoin Address: " . $address->getAddress() . PHP_EOL;
