How Office encrypts Word, Excel, and PPT documents

Encrypt documents using the Office software itself

The Office software itself can be used to encrypt documents. In Word, for example, open the document you want to encrypt, and from the File menu, select information → protect document → Encrypt with password, and after entering the password, the document is protected. Excel and PPT are similar in Chinese file encryption methods.

Another way to set up a document password with Office is to select the file → Save As command, next to the saved button in the Save window, select the Tools Drop-down menu, select General Options, and then set the document access password in the active window.

Convert to zip file with password anti-open

Windows 8-plus systems can read documents directly in the zip, but do nothing with password-coded documents. As a result, we can package our Office documents as zip packages, while adding access passwords to the compressed package. To use good compression for example, right-click the document and select "Good pressure → add to compressed file."

Then in the compressed File Settings window, select the Password tab, enter the compression package open password, confirm after the compression can begin. Windows will not be able to view the Office documents in the compressed package after the password is not available later.

Encrypt documents with Third-party gadgets

We can also use a Third-party encryption gadget encrypt care to encrypt Office documents. After starting the Encrypt care software, drag the encrypted document into the window, enter the password at the top of the window, click on the Encrypt button, and then determine the location of the target file, and the resulting file needs a password to open.
