}關於加密的demo:
<?php
$cipher_list = mcrypt_list_algorithms();//mcrypt支援的加密演算法列表
$mode_list = mcrypt_list_modes(); //mcrypt支援的加密模式列表
// echo strlen('{"source_id": "123312", "source": "qq", "source_name": "hello"}');
function aes256_cbc_encrypt($key, $data, $iv) {
if(16 !== strlen($iv)) $iv = substr($iv, 0, 16);
$padding = 32 - (strlen($data) % 32);
echo "strlen data is",strlen($data);
$data .= str_repeat(chr($padding), $padding);
echo " strlen data is",strlen($data);
return mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $data, MCRYPT_MODE_CBC, $iv);
}
$str_new = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_128,"273d7e70c2d115e6",'0063{"source_id": "123312", "source": "qq", "source_name": "hello"}'
,MCRYPT_MODE_CBC,'273d7e70c2d115e6'));
// echo $str_new,":",strlen($str_new)."\n";
// class A {
// public $source_id;
// public $source;
// public $user_info;
// }
// class B{
// public $name;
// public $gender;
// }
// $a = new A();
// $a->source_id="12333";
// $a->source = "xinshangyun";
// $b = new B();
// $b->name ="testEncrypt";
// $b->gender = 1;
// $a->user_info = $b;
// $data = json_encode($a,true);
// echo $data."\n";
$raw_data = '{"source_id": "123312", "source": "qq", "source_name": "hello"}';
$raw_len = strlen($raw_data);
$body = pack("a{$raw_len}",$raw_data);
$head = pack('N',strlen($body));
$data = $head.$raw_data;
$str = aes256_cbc_encrypt('273d7e70c2d115e62e0e45656ff82b39',$data
,'273d7e70c2d115e62e0e45656ff82b39');
