PHP加密解密类实例分析

   这篇文章主要介绍了PHP加密解密类,实例分析了php实现加密与解密的原理与相关技巧,非常具有实用价值,需要的朋友可以参考下

  本文实例讲述了PHP加密解密类。分享给大家供大家参考。具体分析如下:

  这段代码支持 数组加密 , 密文有效期, 各种对称加密

  其中参数如下:

  * @use ption::en($string, $key);

  * @param String $string 需要加密的字串

  * @param String $skey 密钥

  * @param int $expiry 密文有效期, 加密时候有效, 单位 秒,0 为永久有效

  * @return String

}

}

/**

* @param String $skey 密钥

* @param int $expiry 密文有效期, 加密时候有效, 单位 秒,0 为永久有效

* @return String

*/

static public function en($string = '', $skey = '', $expiry=0)

{

if( is_array( $string ) )

{

$string = json_encode($string); // uicms::json($string, true, 'en');

}

$string = str_pad($expiry ? $expiry + TIME : 0, 10, 0).$string;

$strArr = str_split(base64_encode($string));

$strCount = count($strArr);

$skey = static::md5($skey);

foreach (str_split($skey) as $key => $value)

{

$key

}

return str_replace(self::$original, self::$later, join('', $strArr));

}

/**

* @use ption::de($string, $key);

* @param String $string 需要解密的字串

* @param String $skey 密钥

* @return String

*/

static public function de($string = '', $skey = '')

{

$strArr = str_split(str_replace(self::$later,self::$original,$string),2);

$strCount = count($strArr);

$skey = static::md5($skey);

foreach (str_split($skey) as $key => $value)

{

$key

}

$result = base64_decode(join('', $strArr));

if(substr($result, 0, 10) == 0 || substr($result, 0, 10) - TIME > 0)

{

return substr($result, 10);

}

else

{

return false;

}

}

}

  2. 用法如下:

$str['username'] = 'oschina';

$str['pw'] = '123456';

$str['huoxin'] = '!@#$%^&';

echo "string : " . $str . "
";

echo "encode : " . ($enstring = ption::en($str)) . '
';

echo "decode : " . ption::de($enstring);
