php中如何将mcrypt转换成openssl?
例如
创新互联服务项目包括海阳网站建设、海阳网站制作、海阳网页制作以及海阳网络营销策划等。多年来,我们专注于互联网行业,利用自身积累的技术优势、行业经验、深度合作伙伴关系等,向广大中小型企业、政府机构等提供互联网行业的解决方案,海阳网站推广取得了明显的社会效益与经济效益。目前,我们服务的客户以成都为中心已经辐射到海阳省份的部分城市,未来相信会继续扩大服务区域并继续获得客户的支持与信任!
public function desEncrypt($str,$key) { $iv = $key; $size = mcrypt_get_block_size ( MCRYPT_DES, MCRYPT_MODE_CBC ); $str = $this->_pkcs5_pad ( $str, $size ); return strtoupper( bin2hex( mcrypt_encrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_CBC, $iv ) ) ); } public function desDecrypt($str,$key) { $iv = $key; $strBin = $this->_hex2bin( strtolower( $str ) ); $str = mcrypt_decrypt( MCRYPT_DES, $key, $strBin, MCRYPT_MODE_CBC, $iv ); $str = $this->_pkcs5_unpad( $str ); return $str; } private function _pkcs5_pad($text,$block=8){ $pad = $block - (strlen($text) % $block); return $text . str_repeat(chr($pad), $pad); } private function _pkcs5_unpad($text) { $pad = ord($text{strlen($text)-1}); if ($pad > strlen($text)) return $text; if (strspn($text, chr($pad), strlen($text) - $pad) != $pad) return $text; return substr($text, 0, -1 * $pad); }
替换后:
//要改的加密 public function desEncrypt($str,$key) { // $b = openssl_get_cipher_methods(); // echo ''; // print_r($b); $iv = $key; // $size = mcrypt_get_block_size ( MCRYPT_DES, MCRYPT_MODE_CBC ); // var_dump($size);exit; // $str = $this->_pkcs5_pad ( $str, $size ); // return strtoupper( bin2hex( mcrypt_encrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_CBC, $iv ) ) ); $data = openssl_encrypt($str,"DES-CBC",$key,OPENSSL_RAW_DATA,$iv); $data = strtolower(bin2hex($data)); return $data; } //要改的解密 public function desDecrypt($str,$key) { $iv = $key; // $strBin = $this->_hex2bin( strtolower( $str ) ); // $str = mcrypt_decrypt( MCRYPT_DES, $key, $strBin, MCRYPT_MODE_CBC, $iv ); // $str = $this->_pkcs5_unpad( $str ); // return $str; return openssl_decrypt (hex2bin($str), 'DES-CBC', $key, OPENSSL_RAW_DATA,$iv); }这些网上都有,在作者使用的过程中因为使用的是MCRYPT_DES,无法得知openssl对应的是那种加密方式,所以通过手册找到了openssl_get_cipher_methods();该方法可以找出openssl支持的所有方法,进行替换即可。
