我不确定如何正确编码公钥，我们非常感谢所有的帮助。

Answer 1

以下代码生成密钥，一切都按预期工作，但您的硬编码是一个公钥，它不会对生成的私钥起作用：

<?php     
$config = array(
    "digest_alg" => "sha512",
    "private_key_bits" => 4096,
    "private_key_type" => OPENSSL_KEYTYPE_RSA,
);

// Create the private and public key
$res = openssl_pkey_new($config);

// Extract the private key from $res to $privKey
openssl_pkey_export($res, $privKey);

// Extract the public key from $res to $pubKey
$pubKey = openssl_pkey_get_details($res);
$pubKey = $pubKey["key"];

$data = 'plaintext data goes here';

// Encrypt the data to $encrypted using the public key
openssl_public_encrypt($data, $encrypted, $pubKey);

// Decrypt the data using the private key and store the results in $decrypted
openssl_private_decrypt($encrypted, $decrypted, $privKey);

echo $decrypted;
?>

相反，您应该执行以下操作 test ，生成密钥然后硬编码：

<?php  
$pubKey = '
