函数源码
复制代码 代码如下:
function encrypt($data, $key) {
$prep_code = serialize($data);
$block = mcrypt_get_block_size('des', 'ecb');
if (($pad = $block - (strlen($prep_code) % $block)) $prep_code .= str_repeat(chr($pad), $pad);
}
$encrypt = mcrypt_encrypt(MCRYPT_DES, $key, $prep_code, MCRYPT_MODE_ECB);
return base64_encode($encrypt);
}
function decrypt($str, $key) {
$str = base64_decode($str);
$str = mcrypt_decrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_ECB);
$block = mcrypt_get_block_size('des', 'ecb');
$pad = ord($str[($len = strlen($str)) - 1]);
if ($pad && $pad $str = substr($str, 0, strlen($str) - $pad);
}
return unserialize($str);
}

复制代码 代码如下:
$key = 'okyo.cn';
$data = array('id' => 100, 'username' => 'customer', 'password' => 'e10adc3949ba59abbe56e057f20f883e');
$snarr = serialize($data);
$en = encrypt($data, $key);
$de = decrypt($en, $key);
echo "加密原型：";
print_r($data);
echo "
密钥：$key
加密结果：$en
解密结果：";
print_r($de);
