在php中如何在GET请求中传递加密字符串？

我正在使用以下类加密字符串（使用继承）

继承类，如下所示

class SaferCrypto extends UnsafeCrypto {
const HASH_ALGO = 'sha256';

/**
 * Encrypts then MACs a message
 * 
 * @param string $message - plaintext message
 * @param string $key - encryption key (raw binary expected)
 * @param boolean $encode - set to TRUE to return a base64-encoded string
 * @return string (raw binary)
 */
public static function encrypt($message, $key, $encode = false)
{
    list($encKey, $authKey) = self::splitKeys($key);

    // Pass to UnsafeCrypto::encrypt
    $ciphertext = parent::encrypt($message, $encKey);

    // Calculate a MAC of the IV and ciphertext
    $mac = hash_hmac(self::HASH_ALGO, $ciphertext, $authKey, true);

    if ($encode) {
        return base64_encode($mac.$ciphertext);
    }
    // Prepend MAC to the ciphertext and return to caller
    return $mac.$ciphertext;
}

/**
 * Decrypts a message (after verifying integrity)
 * 
 * @param string $message - ciphertext message
 * @param string $key - encryption key (raw binary expected)
 * @param boolean $encoded - are we expecting an encoded string?
 * @return string (raw binary)
 */
public static function decrypt($message, $key, $encoded = false)
{
    list($encKey, $authKey) = self::splitKeys($key);
    if ($encoded) {
        $message = base64_decode($message, true);
        if ($message === false) {
            throw new Exception('Encryption failure');
        }
    }

    // Hash Size -- in case HASH_ALGO is changed
    $hs = mb_strlen(hash(self::HASH_ALGO, '', true), '8bit');
    $mac = mb_substr($message, 0, $hs, '8bit');

    $ciphertext = mb_substr($message, $hs, null, '8bit');

    $calculated = hash_hmac(
        self::HASH_ALGO,
        $ciphertext,
        $authKey,
        true
    );

    if (!self::hashEquals($mac, $calculated)) {
        throw new Exception('Encryption failure');
    }

    // Pass to UnsafeCrypto::decrypt
    $plaintext = parent::decrypt($ciphertext, $encKey);

    return $plaintext;
}

/**
 * Splits a key into two separate keys; one for encryption
 * and the other for authenticaiton
 * 
 * @param string $masterKey (raw binary)
 * @return array (two raw binary strings)
 */
protected static function splitKeys($masterKey)
{
    // You really want to implement HKDF here instead!
    return [
        hash_hmac(self::HASH_ALGO, 'ENCRYPTION', $masterKey, true),
        hash_hmac(self::HASH_ALGO, 'AUTHENTICATION', $masterKey, true)
    ];
}

/**
 * Compare two strings without leaking timing information
 * 
 * @param string $a
 * @param string $b
 * @ref https://paragonie.com/b/WS1DLx6BnpsdaVQW
 * @return boolean
 */
protected static function hashEquals($a, $b)
{
    if (function_exists('hash_equals')) {
        return hash_equals($a, $b);
    }
    $nonce = openssl_random_pseudo_bytes(32);
    return hash_hmac(self::HASH_ALGO, $a, $nonce) === hash_hmac(self::HASH_ALGO, $b, $nonce);
 }
}

加密字符串如下

$email = 'myemail@domain.com';
$key = 'Some key';
$encrypted_email = $encrypted = SaferCrypto::encrypt($message, $key);

字符串的加密方式如下：

 óÜCu!>Ò·<x0½“—J ‡l¿Ø ;ƒ;›OøVP#ï 1 Sjñ,(ñúrÛòv–~ºyÍg ÷–´´iƒû

---

óÜCu！>Ò·不清楚问题出在哪里，但您可以使用
base64_encode（$encrypted_email）
将字符串作为smth传递，如
HDo1FaXabDHjfxBkpx7YBHNGVeZ/G8FvI2BoxES2rUu3lvNWRo5G0PImiv9IhENv

<a href="?enc=<?=base64_encode($encrypted_email)?>">link</a>

base64\u encode（$encrypted\u email）
将字符串作为smth传递，如
HDo1FaXabDHjfxBkpx7YBHNGVeZ/G8FvI2BoxES2rUu3lvNWRo5G0PImiv9IhENv

<a href="?enc=<?=base64_encode($encrypted_email)?>">link</a>

哈希不匹配
是否有哈希或加密？（哈希无法解密）@chris85如果你查看
decrypt
方法，方法
hashEquals
会抛出错误。你的问题应该包含所有信息。用完整的信息编辑描述。加密例程生成的字符在查询字符串中根本无效。考虑应用Base64传输编码。还有：HTTPS呢？我认为与您在这里尝试的操作相比，这更安全，也更少麻烦。
