PHP加密/解密使用OpenSSL不爲我工作

Question

我想使用PHP和OpenSSL使用公鑰加密一些數據，然後再解密它。

我產生public.key和private.key使用此代碼：

// generate private key 
$privateKey = openssl_pkey_new(array(
    'private_key_bits' => 1024, 
    'private_key_type' => OPENSSL_KEYTYPE_RSA, 
)); 
// write private key to file 
openssl_pkey_export_to_file($privateKey, 'private.key'); 
// generate public key from private key 
$publicKey = openssl_pkey_get_details($privateKey); 
// write public key to file 
file_put_contents('public.key', $publicKey['key']); 
// clear key 
openssl_free_key($privateKey); 

我的代碼進行加密和解密基本上是直接從PHP文件：

// data to encrypt 
$data = "This is a long string or other bit of data that i want to encrypt"; 

// ==== ENCRYPT ==== 

// read public key 
$publicKey = file_get_contents("public.key"); 
$publicKey = openssl_get_publickey($publicKey); 

// encrypt data using public key into $sealed 
$sealed = ''; 
openssl_seal($data, $sealed, $ekeys, array($publicKey)); 
openssl_free_key($publicKey); 

// ==== DECRYPT ==== 

// get private key to decrypt with 
$privateKey = file_get_contents("private.key"); 
$privateKey = openssl_get_privatekey($privateKey); 

// decrypt data using private key into $open 
$open = ''; 
openssl_open($sealed, $open, $env_key, $privateKey); 
openssl_free_key($privateKey); 


// display decrypted data: 
echo "<p>Decrypted data: ".$open; 

任何人有任何線索爲什麼它不工作，或者至少有一種方法來查明發生了什麼錯誤？

您忘記了這個說法嗎？

$env_key = $ekeys[0]; 

我發現我的答案通過讀取openssl_seal()
