1. ACCESS数据能直接导出到EXCEL表格,但如何实现对导出的EXCEL表格加密呢
刚写了一个:
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：菜单“工具”—〉“保护”—〉“保护工作表”，根据提示输入密码和要保护的内容。
方法二：菜单“工具”—〉“选项”—〉“安全性”，在对应的栏输入密码。
方法三：F12，在“另存为”窗口点击“工具”—〉“常规选项”，在弹出的窗口输入密码
方法四：如果你使用NTFS磁盘保存excel文件，右键点击excel文件选“属性”——〉“高级”，“加密文档以保护数据”前面打勾。这个要特别小心，一定记得导出密钥，否则重装系统或者更改密码后就打不开了。
3. 在c#中如何把从界面导出的excel加密并能解密
你拥有修改读写权限的话，进“工具”——“选项”——“安全性”，把密码去丢就行了。
没有修改读写权限的话，找个去excel密码的软件去密。
4. php 导出Excel 加水印,加密
composer require phpoffice/phpspreadsheet
然后直接按示例操作就好了
5. 从某个系统中导出的电子表 身份证号码是一串字符怎么回事怎么转换回来
你好，这个有可能是加密的，系统为了保护个人隐私所以加密的。一般只有系统高级的管理员可以查看。
6. mysql里的数据如何实现导出后变成加密的数据
好像没有；
其实也可以想象到，既然 可以导出，你可以在导出后进行处理加密！
如果备份数据，倒是可以直接加密的。
网上可以直接找到

7. sql 导出表的数据password <9MoZNpexGbg=> 解出密码是*963. 能告诉我是怎么加密的吗
这会有无数个答案。需要取很多的样本才有可能猜出。
最简单直接的一种是：
9Mo代表*
ZNp代表9
exG代表6
bg=代表3
......
函数里对每个要加密的字符设置一个对应的字串进行加密。
8. 如何加密导出mysql数据库
导出数据库文件，用7z打包成带密码的压缩文件就行了。
9. 从软件导出的excel数据被加密,如何解密
用不着软件
EXCEL工作表保护密码破解
方法:
1\打开文件
2\工具---宏----录制新宏---输入名字如:aa
3\停止录制(这样得到一个空宏)
4\工具---宏----宏,选aa,点编辑按钮
5\删除窗口中的所有字符(只有几个),替换为下面的内容:(复制吧)
6\关闭编辑窗口
7\工具---宏-----宏,选AllInternalPasswords,运行,确定两次,等2分钟,再确定.OK,没有密码了!!
内容如下：

此方法，本人亲自试过，确实不错
