The first type: WinDOS encryption method, suitable for a single word encryption, not conducive to multiple word encryption.
Now I'm going to talk about ways and means to protect Word 2003 files by using Word for years of experience. Hide document Records What do we see first when we open Word? By the click of the "File" menu, the 4 files that you have recently used are listed by default. In this way, we open the file will be completely exposed, no need to find can easily be found by others. For the sake of confidentiality, we often do not want others to see their recently edited files, to achieve this purpose, as long as the "tools" → "Options" → "General" tab does not select the "list of recent files" can be. So no one can find the files that have been used recently? The answer is, of course, negative. In general, the Documents submenu of the Windows Start menu lists all the files that users have recently used, and the sensitive content should be purged in a timely manner. We can click the "open" → "settings" → "Taskbar and Start Menu" → "advanced" tab in the "Clear" button.
To set a password for a document long text entry is finally complete, if you do not want those unauthorized users to use your saved files, you should set a password for it. Open "file" → "Save As" → Click "Security Options" in the "Tools" button, enter the password in the password bar, confirm the input. (as pictured)
Here's how Word provides two types of passwords for File Protection: Open Permissions Password Open password--restrict unauthorized users from opening documents; Restrict unauthorized users from opening documents; Open Permissions password restrict unauthorized users to open the document "Modify permission Password"--Restrict unauthorized users to make changes to the document, users who do not have the password to modify permissions can open the document only as read-only. The two passwords are independent of each other and can be set separately according to their own needs. The maximum length of a password is 15 characters and is case-sensitive. Also, select the recommend open document as read-only option, so that a prompt that advises users to open read-only appears before the document is opened, and the document opens in the normal way if we choose No to accept the recommendation.
Need to remind everyone, do not think that add a password to everything OK, for many cracked Office document password software, the length of too short or more regular Office document password can be said to be fragile. So, the real need for encryption of important documents, we need to pay more attention to the use of digital, letter-case mixed encryption. Small measures after encryption even if the document has been encrypted, I can still learn something about your document just by moving the mouse. You can see part of the body of the document in the title item of the Summary tab by right-clicking the document and choosing Properties from the pop-up menu. Why is that? Many people are accustomed to entering the text directly when editing a new document and then giving the document a title. As a result, Word automatically saves the first dozens of words in the body as document summary information. So in order to make their privacy better protected, we have to form the first to enter the title of the article or in time to manually change the title of the habit. If you don't want people to know about your user information, you should also do some modification work (including "User name", "initials", "mailing address", etc.) in the tools → options → user information tab. Easy to secure review through the above methods of processing documents, can be said to be basically safe. However, once we have finished a document, we may need to give it to someone else to review it and use the tools → protect document command to protect the original document. In this way, the changes that others make to the document's manuscript are recorded in the form of revision marks or annotation marks.
The second way: the use of encryption software, suitable for multiple word encryption
1. First, the Internet to download a cryptographic software, such as the Shadow Encryption king, this is a professional document encryption software. With the fast Shadow encryption king to his hard drive to create a safe. As shown in figure:
2. After the successful creation, you can then log in to the safe you created. The generated safe will map a Z disk, as shown in the figure:
3. Open the safe, and then the need to encrypt the Word file into the z disk, and then exit the safe, it is easy to encrypt these word.
