1. Document password protection: In Word, the simplest encryption method is to set a document password.

In this way, every time you open a document, you need to enter a password to view the content, ensuring the security of the document.

In the "Review" option, you can select "Protected Document" - "Restrict Editing", then set editing permissions and set password protection. This can effectively control the modification scope of the document and protect the integrity of the document.

You can check whether the signature is valid after the document is modified to ensure the authenticity of the document.

3. Things to note when encrypting Word documents

1. Password selection: When setting a password, it is recommended to use a complex password, including numbers, letters and special characters, to avoid using simple passwords that are easily cracked and ensure the security of the document.
2. Password management: When setting a password to protect a document, be sure to remember the password to avoid the embarrassing situation of being unable to open the document if you forget it. Also consider saving your passwords in a safe place in case you need them.
3. Back up important documents: Although encryption can protect the security of documents, sometimes passwords may be lost or forgotten. Therefore, it is recommended to back up the document before encrypting it to ensure that the original document can be retrieved even if the password is lost.
