1. ACCESS數據能直接導出到EXCEL表格,但如何實現對導出的EXCEL表格加密呢
剛寫了一個:
Dim wb As Object
Dim ws As Object
Dim xl As Object
Dim pword As String
Set xl = CreateObject("excel.application")
Set wb = xl.Workbooks.Open("C:\book1.xlsx")
Set ws = wb.Worksheets("sheet1")
xl.Visible = False
ActiveWorkbook.Sheets(1).Select
pword = "123"
ws.Protect pword
wb.Close savechanges:=True
Set xl = Nothing
MsgBox "protect successfully"
2. Microsoft Excel 工作表如何加密
方法一：菜單「工具」—〉「保護」—〉「保護工作表」，根據提示輸入密碼和要保護的內容。
方法二：菜單「工具」—〉「選項」—〉「安全性」，在對應的欄輸入密碼。
方法三：F12，在「另存為」窗口點擊「工具」—〉「常規選項」，在彈出的窗口輸入密碼
方法四：如果你使用NTFS磁碟保存excel文件，右鍵點擊excel文件選「屬性」——〉「高級」，「加密文檔以保護數據」前面打勾。這個要特別小心，一定記得導出密鑰，否則重裝系統或者更改密碼後就打不開了。
3. 在c#中如何把從界面導出的excel加密並能解密
你擁有修改讀寫許可權的話，進「工具」——「選項」——「安全性」，把密碼去丟就行了。
沒有修改讀寫許可權的話，找個去excel密碼的軟體去密。
4. php 導出Excel 加水印,加密
composer require phpoffice/phpspreadsheet
然後直接按示例操作就好了
5. 從某個系統中導出的電子表 身份證號碼是一串字元怎麼回事怎麼轉換回來
你好，這個有可能是加密的，系統為了保護個人隱私所以加密的。一般只有系統高級的管理員可以查看。
6. mysql里的數據如何實現導出後變成加密的數據
好像沒有；
其實也可以想像到，既然 可以導出，你可以在導出後進行處理加密！
如果備份數據，倒是可以直接加密的。
網上可以直接找到

7. sql 導出表的數據password <9MoZNpexGbg=> 解出密碼是*963. 能告訴我是怎麼加密的嗎
這會有無數個答案。需要取很多的樣本才有可能猜出。
最簡單直接的一種是：
9Mo代表*
ZNp代表9
exG代表6
bg=代表3
......
函數里對每個要加密的字元設置一個對應的字串進行加密。
8. 如何加密導出mysql資料庫
導出資料庫文件，用7z打包成帶密碼的壓縮文件就行了。
9. 從軟體導出的excel數據被加密,如何解密
用不著軟體
EXCEL工作表保護密碼破解
方法:
1\打開文件
2\工具---宏----錄制新宏---輸入名字如:aa
3\停止錄制(這樣得到一個空宏)
4\工具---宏----宏,選aa,點編輯按鈕
5\刪除窗口中的所有字元(只有幾個),替換為下面的內容:(復制吧)
6\關閉編輯窗口
7\工具---宏-----宏,選AllInternalPasswords,運行,確定兩次,等2分鍾,再確定.OK,沒有密碼了!!
內容如下：

此方法，本人親自試過，確實不錯
感謝寫出這段編碼的同志
