今天写了一个php的AES加密类。适用于Yii的扩展。
如果不用在Yii框架中，把代码中Yii::app()->params['encryptKey'] 换成你对应的默认key就可以了。
类代码:
<"\0");
}
/**
* Returns the length of the given string.
* If available uses the multibyte string function mb_strlen.
* @param string $string the string being measured for length
* @return integer the length of the string
*/
private static function strlen($string)
{
return extension_loaded('mbstring') ? mb_strlen($string,'8bit') : strlen($string);
}
/**
* Returns the portion of string specified by the start and length parameters.
* If available uses the multibyte string function mb_substr
* @param string $string the input string. Must be one character or longer.
* @param integer $start the starting position
* @param integer $length the desired portion length
* @return string the extracted part of string, or FALSE on failure or an empty string.
*/
private static function substr($string,$start,$length)
{
return extension_loaded('mbstring') ? mb_substr($string,$start,$length,'8bit') : substr($string,$start,$length);
}
}
