Encryption-program

php写的一个简单的加密代码的程序

##加密规则

用特定字符代替原有字符，具体规则为数据库记录下字符串并给一个自动增量值，如变量$abc，会把abc存入数据库，自增量为1，按照十进制转八进制的规则转换成15位长度的数，并按键值获取对应字符；如000000000000001转换后为LLLLLLLLLLLLLLl;以极低可读性达到类似加密效果。

可替换字符如下:

'0' ='L', '1' ='l', '2' ='I', '3' ='i', '4' ='O', '5' ='o', '6' ='J', '7' ='j',

###需要过滤的变量

目前不需要加密的变量有$this,$_COOKIE,$_ENV,$_FILES,$_GET,$_POST,$_REQUEST,$_SERVER,$_SESSION

##加密代码片段示例

public function getDataList($model, $where, $order = "id desc", $page = 0, $listRows = 0, $fields = "", $templateName = 'list', $fnName = 'dataList'){ if (empty($listRows)) { $listRows = $this->rows; } if (empty($page)) { $page = empty($_REQUEST['p']) ? 0 : $_REQUEST['p']; } $return = array(); $tempObj = $model->where($where)->order($order); if ($fields) { $tempObj = $model->field($fields); } $list = $tempObj->where($where)->page($page, $listRows)->select(); $count = $model->where($where)->count(); if (method_exists($this, "_after_".$fnName)) { $fnName = "_after_".$fnName; $this->$fnName($list); } return ['list'=>$list, 'count'=>$count]; }

混淆后

public function getDataList($LLLLLLLLLLLLLOi, $LLLLLLLLLLLLlLo, $LLLLLLLLLLLLlLJ = "id desc", $LLLLLLLLLLLLlLj = 0, $LLLLLLLLLLLLllL = 0, $LLLLLLLLLLLLlll = "", $LLLLLLLLLLLLllI = 'list', $LLLLLLLLLLLLlli = 'dataList'){ if (empty($LLLLLLLLLLLLllL)) { $LLLLLLLLLLLLllL = $this->LLLLLLLLLLLLLJo; } if (empty($LLLLLLLLLLLLlLj)) { $LLLLLLLLLLLLlLj = empty($_REQUEST['p']) ? 0 : $_REQUEST['p']; } $LLLLLLLLLLLLllO = array(); $LLLLLLLLLLLLllo = $LLLLLLLLLLLLLOi->where($LLLLLLLLLLLLlLo)->order($LLLLLLLLLLLLlLJ); if ($LLLLLLLLLLLLlll) { $LLLLLLLLLLLLllo = $LLLLLLLLLLLLLOi->field($LLLLLLLLLLLLlll); } $LLLLLLLLLLLLLOI = $LLLLLLLLLLLLllo->where($LLLLLLLLLLLLlLo)->page($LLLLLLLLLLLLlLj, $LLLLLLLLLLLLllL)->select(); $LLLLLLLLLLLLllJ = $LLLLLLLLLLLLLOi->where($LLLLLLLLLLLLlLo)->count(); if (method_exists($this, "_after_".$LLLLLLLLLLLLlli)) { $LLLLLLLLLLLLlli = "_after_".$LLLLLLLLLLLLlli; $this->$LLLLLLLLLLLLlli($LLLLLLLLLLLLLOI); } return ['list'=>$LLLLLLLLLLLLLOI, 'count'=>$LLLLLLLLLLLLllJ]; }
