PHP与asp.net C#可共用的可逆加密算法_PHP教程

因为工作需我们需要在php中生成加密然后在asp.net中接受过来的密码再解密，下面我找到一个PHP与asp.net C#可共用的可逆加密算法，有需要了解的同学可参考。

php加密算法

代码如下

复制代码

class DES {     var $key;     var $iv; //偏移量         function DES($key = '11001100', $iv=0 ) {     //key长度8例如:1234abcd         $this->key = $key;         if( $iv == 0 ) {             $this->iv = $key; //默认以$key 作为 iv         } else {             $this->iv = $iv; //mcrypt_create_iv ( mcrypt_get_block_size (MCRYPT_DES, MCRYPT_MODE_CBC), MCRYPT_DEV_RANDOM );         }     }         function encrypt($str) {     //加密，返回大写十六进制字符串         $size = mcrypt_get_block_size ( MCRYPT_DES, MCRYPT_MODE_CBC );         $str = $this->pkcs5Pad ( $str, $size );         return strtoupper( bin2hex( mcrypt_cbc(MCRYPT_DES, $this->key, $str, MCRYPT_ENCRYPT, $this->iv ) ) );     }         function decrypt($str) {     //解密         $strBin = $this->hex2bin( strtolower( $str ) );         $str = mcrypt_cbc( MCRYPT_DES, $this->key, $strBin, MCRYPT_DECRYPT, $this->iv );         $str = $this->pkcs5Unpad( $str );         return $str;     }         function hex2bin($hexData) {         $binData = "";         for($i = 0; $i             $binData .= chr ( hexdec ( substr ( $hexData, $i, 2 ) ) );         }         return $binData;     }     function pkcs5Pad($text, $blocksize) {         $pad = $blocksize - (strlen ( $text ) % $blocksize);         return $text . str_repeat ( chr ( $pad ), $pad );     }         function pkcs5Unpad($text) {         $pad = ord ( $text {strlen ( $text ) - 1} );         if ($pad > strlen ( $text ))             return false;         if (strspn ( $text, chr ( $pad ), strlen ( $text ) - $pad ) != $pad)             return false;         return substr ( $text, 0, - 1 * $pad );     }     } ?>

asp.net程序代码

 

代码如下
