[Editor's note: we always face a variety of data in our lives. We will choose various encryption methods for the data that requires confidentiality. How can we encrypt documents, tables, presentations, and databases created using office software ?]
In our daily work, we often use some Office software (Microsoft Office and WPS Office) to create documents, tables, presentations and databases. For the sake of confidentiality, we usually need to encrypt these files.
1. Encrypt Microsoft Office files
1. Encrypt Word, Excel, and PowerPoint files
The methods for encrypting these three types of files are similar. They can be implemented irregularly in the following two ways.
Method 1: Set options. In the preceding application window (such as Word2002), run the "tool options" command to open the "options" dialog box and switch to the "Security" tab (1 ), after setting "Open permission password" and "Modify permission password", confirm to exit and save the current document.

When you "save" or "Save as" for the preceding documents (such as "presentations"), open the "Save as" dialog box and press the drop-down button on the right of the "Tools" button on the toolbar, in the subsequent drop-down list, select "Security Options" to open the "Security Options" dialog box (2). After setting "Open permission password" and "Modify permission password, exit, and then save the document.

[Note] ① you can set only one or all of the "open permission password" and "Modify permission password" based on your confidentiality. (The two passwords can be the same, ). ② For PowerPoint, the encryption function is added only in versions 2002 and later. ③ When using Channel 2 to encrypt files, select "security measure options" in Word, and select "general options" in Excel ".
2. Encrypt Access Database Files
Start Access2002, run the "open file" command, open the "open" dialog box, select the database file to be encrypted, and then press the drop-down button on the right of the "open" button in the lower right corner, in the following drop-down list (see figure 3), select the "open exclusively" option to open the corresponding database file.

2. Encrypt WPS Office files
Encrypted files created using Kingsoft text, Kingsoft table, and Kingsoft demo components in WPS Office are in the same method and easy to operate.
In the corresponding component (such as "Kingsoft table 2002") window, run the "file encryption password" command, open the "password" dialog box (5), and confirm the return, save (or save another) The current file.
