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 << 4;

ok!~ At this point, the blogger continues to work! ~~
