Question

我正在尝试根据这个＆＃34; How are ethereum addresses generated?＆＃34;之后的给定私钥生成以太坊地址。并使用此Keccak-256 Ethereum implementation. 但它显示了这个错误：

Warning: openssl_pkey_get_details() expects parameter 1 to be resource, boolean given in /localweb/getethaddress.php on line 15

我的实施：

    // Format the private key as PEM
    $header_private_key = "-----BEGIN EC PRIVATE KEY-----\n";
    $footer_private_key = "\n-----END EC PRIVATE KEY-----";

    $eth_private_key = $header_private_key . "1a63b5c735d66d827f40f7d3a257da777cd7997d48bd5d319c36683c0ad3b1de" . $footer_private_key;

    // Load private key from a string
    $private_key = openssl_pkey_get_private($eth_private_key);
    var_dump($private_key);
    while ($msg = openssl_error_string())
        echo "openssl_pkey_get_private " . $msg . "<br />\n";

    // Get the Public key
    $_public_key = openssl_pkey_get_details($private_key)['key'];
    $eth_public_key = openssl_pkey_get_public($_public_key);

    // hash the public key
    $hash_public_key = Keccak256\Keccak256::hash($eth_public_key, 256);; 
    $eth_address = '0x' . substr($hash_public_key, -40);

    // compare the output
    echo 'Your generated address: ' . $eth_address . '<br>';
    echo 'Myetherwallet address: 0x47180b59dd8c81f46186900bbd29cbf675b3fbd9';


    /*
