XOR string encryption method after base64 encryption

Encryption

function encode($str,$key)
{
    $res = base64_encode($str);
    $code = $res^$key;
    return $code;
}

Decryption

function decode($str,$key)
{
    return base64_decode($str^$key);
}

Full code example:

$str = '111021';
$key = 'APPYJJ-PHONE-LAZY';
function encode($str,$key)
{
    $res = base64_encode($str);
    $code = $res^$key;
    return $code;
}
$str = encode($str,$key);
print_r($str);
echo "<hr>";
function decode($str,$key)
{
    return base64_decode($str^$key);
}
print_r(decode($str,$key));
  • The whole program is very simple~ According to logical thinking, it should be difficult to crack, if others don’t know your secret key;

  • If you still feel unsafe. So I’m just going to throw some light here; I suggest you continue to use shift operations in the encryption and decryption process

//加密的时候;
$a = $str >> 4;
//解密的时候则相反
$a = $str <p>ok!~ At this point, the blogger continues to work! ~~</p><p class="article fmt article__content"></p><h2 id="XOR-string-encryption-method-after-base-encryption">XOR string encryption method after base64 encryption</h2><blockquote><p>Encryption</p></blockquote><pre class="brush:php;toolbar:false">function encode($str,$key)

How can you check if a PHP session has already started?How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
