php 无法从 RNCryptor 上的 $_get 请求中解密密码

Question

我正在尝试解密从越狱中获取的密码 iphone 但我不知道为什么当我将 $_get 值设置为时 RNCryptor 解密函数总是 return 空值功能，但是当我将原始数据用于解密功能时它工作正常。有人知道这个问题吗？这是 return 空值的代码：

if(isset($_GET['info'])){

    $password = "mykey"
    $base64Encrypted = $_GET['info'];
    $cryptor = new \RNCryptor\Decryptor();
    $plaintext = $cryptor->decrypt($base64Encrypted, $password);
    echo $plaintext;//=> this code block return null value

}else{
    echo 'not have info params';
}

但是当我将原始密码数据放入此代码块时运行很好：

if(isset($_GET['info'])){

    $password = "mykey"
    $base64Encrypted = 'AwEEeG/CU0VHXVGvuRcm805DvvVQi32NPjmlQxoaniIL9ngCjNY1Su4jEb2IfCILBvhKIdjl1znysm6SMiFmRZi2St8wCcWCmnImdwAPLysB/g==';
    $cryptor = new \RNCryptor\Decryptor();
    $plaintext = $cryptor->decrypt($base64Encrypted, $password);
    echo $plaintext;//=> this code block return the original value of cipher

}else{
    echo 'not have info params';
}

抱歉，我刚刚发现 $_get 参数在通过 URL 发送时被编码，所以所有 '+' 字符都已更改为 space 字符。这是我的解决方案：

 $password = "mykey";
    $stringCipher = explode('?info=', $_SERVER['REQUEST_URI'], 2);
    $base64Encrypted = $stringCipher[1];
    $cryptor = new \RNCryptor\Decryptor();
    $decryptSerial = $cryptor->decrypt($base64Encrypted, $password);
