带有字符串公钥的PHP OpenSSL公钥加密

Question

我有一个公钥

-----BEGIN PUBLIC KEY-----

存储为 base64 编码的字符串(在 MySQL 中，设置为 $row['public_key'])

在 PHP 中。我正在尝试使用此字符串来加密字符串数据，但是当我使用以下代码时它没有告诉我原因就失败了:

$success = openssl_public_encrypt($data, $encrypted, base64_decode($row['public_key']));

运行上述代码时，$success 始终为 false，$encrypted 为空白。我已经尝试通过 openssl_pkey_get_public() 运行公钥并将资源发送到 openssl_public_encrypt() 也没有成功。写入文件不是一种选择，存储私钥也不是。

有谁知道如何让它工作？ (或者它对其他所有人都有效，而这只是一个奇怪的服务器问题？)

编辑:由于我的问题似乎有些困惑，这里是我正在使用的测试代码及其输出。 (注意:我已经删除了 base64 编码，只是为了看看是否有任何不同)

$pubkey = openssl_get_publickey($row['public_key']);
$publicKey = openssl_pkey_get_details($res);
$encrypted = null;
$success = openssl_public_encrypt($data, $encrypted, $pubkey);
print "\npubkey1 " . $row['public_key'];
print "\npubkey2 " . $pubkey;
print "\npubkey3 " . $publicKey;
print "\npubkey4 " . $publicKey["key"];
print "\nencryption " . ($success ? 'true' : 'false') . ' "' . $encrypted . '"';
$success = openssl_public_encrypt($data, $encrypted, $row['public_key']);
print "\nencryption2 " . ($success ? 'true' : 'false') . ' "' . $encrypted . '"';   

输出:

pubkey1 -----BEGIN PUBLIC KEY-----

pubkey2 Resource id #50
pubkey3 
pubkey4 
encryption false ""
encryption2 false ""

Answer 1

您应该传递给此函数的键是一个 PHP 资源对象，而不是键本身的字符串表示形式。

$pubkey = openssl_get_publickey(base64_decode($row['public_key']));
$success = openssl_public_encrypt($data, $encrypted, $pubkey);
