爲什麼有票要重新打開呢？有沒有關於制定規範的元討論？ – 2017-02-14 05:52:58

HTTPS通常在Web服務器上實現，而不是在腳本語言中實現。例如，如果您要將此項目部署到Apache服務器，則可以檢出the Apache documents relating to SSL。

如果您只是想通過HTTPS發佈表單數據，Apache應該能夠爲您處理。但是，如果你想使用OpenSSL和PHP生成密鑰對數據進行加密，我寫這兩篇文章可能會使用你：

不幸的是，現在鏈接已經死亡。 – Code4R7 2018-01-29 18:05:12

這裏有

function encryptData($source, $privateKey) 
{ 
    $maxLength = 117; 

    $output = ""; 
    while ($source) 
    { 
     $slice = substr($source, 0, $maxLength); 
     $source = substr($source, $maxLength); 

     openssl_private_encrypt($slice, $encrypted, $privateKey); 
     $output .= $encrypted; 
    } 

    return $output; 
} 

function decryptData($source, $publicKey) 
{ 
    $maxLength = 128; 

    $output = ""; 
    while ($source) 
    { 
     $slice = substr($source, 0, $maxLength); 
     $source = substr($source, $maxLength); 

     openssl_public_decrypt($slice, $decrypted, $publicKey); 

     $output .= $decrypted; 
    } 

    return $output; 
} 

// usage 
$myPrivateKey = ""; // your generated private key 
$myPublicKey = ""; // your generated public key 

$rawText = "lorem ipsum"; 

$crypted = encryptData($rawText, $myPrivateKey); 
$decrypted = decryptData($crypted, $myPublicKey);

生成您的公/私鑰對，只是執行以下命令：

關於如何使用OpenSSL和PHP的一些例子

openssl genrsa -out private_key.pem 1024 
openssl rsa -pubout -in private_key.pem -out public_key.pem

您將在當前目錄中找到兩個鍵。如果您需要將它們添加到變量中，請注意空格。

你想用php生成一對密鑰嗎？

$NEW_KEY = openssl_pkey_new(array(
    'private_key_bits' => 1024, 
    'private_key_type' => OPENSSL_KEYTYPE_RSA, 
     )); 

openssl_pkey_export_to_file($NEW_KEY, 'private.key'); 

$NEW_KEY_DETAILS = openssl_pkey_get_details($NEW_KEY); 
file_put_contents('public.key', $NEW_KEY_DETAILS['key']); 

openssl_free_key($NEW_KEY);

你已經有鑰匙了嗎？

$public = "-----BEGIN PUBLIC KEY-----

你走吧，盡情享受吧！
