How to encrypt a document

When editing some very important Word documents, especially some confidential documents, adding passwords to word documents is a very useful function and a security guarantee. In order to prevent others from seeing the content, we must add a password to the Word document. After the Word document is encrypted, anyone must enter the correct password to view the content.

The following methods are shared with word document encryption, and the methods of word2003 and word2007 are introduced respectively.

Word2003 document encryption method

How to encrypt the files in the computer?

Win XP file encryption method

I. Format of office documents

1, Word file

To encrypt a Word file, first open the file to be encrypted, click Tools menu → Options to open the Options dialog box, and select the Save tab. Enter passwords in the "Open Permission Password" and "Modify Permission Password" input boxes. It should be noted that the previous password is used to open the file. Without this password, the file cannot be opened. The latter is based on the former to set whether the opener has the right to modify the file. If not, it can only read and cannot modify the content.

2.excel file

The encryption method of Excel file is different from that of Word file. After editing the file, click File menu → Save As. , the Save As dialog box pops up, and then click the Tools button on the toolbar to pop up the drop-down menu, select the general option, and enter the initial password and modify the password in the pop-up settings window. Click OK and save.

Step 3 access files

The encryption of the Access database file is carried out according to the following steps:

(1) Close the database. If the database is shared on the network, make sure that all other users have closed the database.

(2) Make a copy of the database and store it in a safe place.

(3) Click the "Open" command in the "File" menu.

(4) Click the arrow to the right of the "Open" button, and then click "Open Exclusive".

5] On the Security submenu of the Tools menu, click the Set Database Password command.

[6] In the password box, type your own password. Passwords are case-sensitive.

(7) In the verification box, type the password again to confirm, and then click OK.

This completes the password setting. The next time you open the database, a dialog box asking for a password will be displayed.

4.WPS file

WPS file encryption is very simple, just click File menu → Save As. , a dialog box pops up. Check the "File Encryption" checkbox to pop up the "Set Password" dialog box. Enter the password in the text box first, and then select the encryption type, where "ordinary encryption" is suitable for most cases and "top secret encryption" is suitable for cases with high confidentiality requirements. Moreover, according to Jinshan Company, they can help customers to delete files encrypted by "ordinary encryption", but they can't do anything about files encrypted by "top secret encryption", so we should pay attention to keeping passwords well to avoid unnecessary losses.

Second, compress the file.

1、Winzip

Winzip is the most popular compression and decompression software. Of course, it also provides a very simple encryption function.

It is best to create a new blank compressed file and add the files to be compressed to the compressed file. Click "Password" in the "Options" menu. . "command, the password setting window will pop up, and enter the set password in the text box. As you type, you want the password in the text box to be invisible. Please select the Mask Password check box.

2、Winrar

Now Winrar is likely to replace Winzip, so we need to learn the encryption method of Winrar. Encryption with Winrar can be done in graphical interface and command line mode.

In the graphical interface, you can press Ctrl+P or select a password from the file menu to pop up the "Enter Default Password" dialog box, and then enter it.

Description:

A. If the "Show Password" option is disabled, you will be asked to enter your password twice to ensure it is correct.

B. If "Encrypt File Name Option" is set, WinRAR

Encrypt not only the data, but also all sensitive areas of the compressed package, such as file name, size, attributes, comments and other data blocks, which provides a higher level of security. In the compressed package encrypted with this command, even the file list cannot be viewed without a password. This option only makes sense when compressing data into a RAR compressed package, and is ignored when decompressing data with a default password or compressing it into a ZIP format.

In command line mode, you can operate in the following format:

WinRAR -

Third, Windows 2000/XP encryption.

Win2000/XP provides the function of encrypting folders, and we can certainly use it to protect files. Before using the encryption function provided by the system, you should make sure that the partition format of the folder you want to encrypt is NTFS, because this function can only be used under NTFS.

(1) Use Windows 2000 Explorer to select the file or folder for which you want to set encryption properties.

(2) Click the right mouse button and select Properties to start the Windows 2000 Properties dialog window.

(3) Click the Advanced button in the General tab to start the Advanced Properties dialog box.

(4) Select the "Encrypt content to protect data" check box in the "Compression or encryption properties" box, and click [OK] to complete the encryption of the file or folder.

How to encrypt files?

Encryption is the process of converting data into a format that others cannot read. If the data is stored on the hard disk, you can use EFS to automatically encrypt the data. Note: Administrators can recover data encrypted by other users.

(Note: Microsoft Windows XP Home Edition has no EFS function. )

How to encrypt files

You can only encrypt files on volumes formatted as NTFS file systems. To encrypt files, follow these steps:

1. Click Start, point to All Programs, point to Accessories, and then click Windows Explorer.

2. Locate the file you want to encrypt, right-click the file, and then click Properties.

3. On the General tab, click Advanced.

4. Under Compression or Encryption Properties, select the Encrypt content to protect data check box, and then click OK.

5. Click OK.

If the file to be encrypted is located in an unencrypted folder, an encryption warning dialog box will appear. Please use one of the following steps:? If you only want to encrypt files, click Encrypt files only, and then click OK. ? If you want to encrypt the file and its folder, click Encrypt File and its parent folder, and then click OK. If another user tries to open the encrypted file, the attempt will fail. For example, if another user tries to open an encrypted Microsoft Word document, a message similar to the following will appear:

Word cannot open this document: the user name does not have access rights.

(Drive: \ File name. doc)

If another user tries to copy or move the encrypted file to another location on the hard disk, the following message will appear:

Error copying file or folder.

Cannot copy file name: Access denied.

Make sure that the disk is not full or write-protected and that the file is not in use.

Troubleshooting? You cannot encrypt files or folders on a volume that uses the FAT file system.

You must store the file or folder you want to encrypt on an NTFS volume. ? You cannot store encrypted files or folders on an untrusted remote server.

To solve this problem, configure the remote server as a trusted delegation. To this end: 1. Log on to the domain controller with an administrator privilege account. 2. Start the Active Directory Users and Computers snap-in. 3. In the left pane, expand the domain container. Locate the target server, right-click it, and then click Properties. 4. On the General tab, select the Trust this computer as a proxy check box, if it is not already selected. When the message "Active Directory" appears, click OK. Click ok, and then log off the Active Directory users and computers. ? You cannot access encrypted files from Macintosh client computers. ? You can't open documents stored by other users in the encrypted folder you created.

If another user creates a document in an encrypted folder, the document will be encrypted (by default) so that only that user can access it. Therefore, the folder you encrypted may contain files that you cannot open. If you need to access these files, please add your user account to the list of users who enjoy encrypted files.

How do I encrypt my document?

It is highly recommended that the high-intensity folder encryption master 8000 ⅶ.36 ber/softhtml/268 can encrypt any folder, and the address can be found at will. I wonder if it can be encrypted and decrypted in NTFS format. NTFS is an advanced file system, which provides security and reliability supported by WinNT and higher versions.

In Win2000 and WinXP, NTFS can also provide advanced functions such as file and folder permissions, encryption, disk quota and compression. 1. Encrypt files or folders 1: Open Windows Explorer.

Step 2: Right-click the file or folder you want to encrypt, and then click Properties. Step 3: On the General tab, click Advanced.

Select the "Encrypt content to protect data" check box, and pay attention to the following five points when encrypting: 1. To open Windows Explorer, click Start → Programs → Accessories, and then click Windows Explorer. 2. Only files and folders on NTFS partition volumes can be encrypted, and files and folders on FAT partition volumes are invalid.

3. Compressed files or folders can also be encrypted. If you want to encrypt a compressed file or folder, the file or folder will be decompressed.

4. Files marked with the "System" attribute cannot be encrypted, nor can files located in the systemroot directory structure be encrypted. 5. When encrypting a folder, the system will ask whether to encrypt its subfolders at the same time.

If "Yes" is selected, its subfolder will also be encrypted, and all files and subfolders added to this folder in the future will be automatically encrypted when added. Step 1: Open Windows Explorer.

Step 2: Right-click the encrypted file or folder, and then click Properties. Step 3: On the General tab, click Advanced.

Step 4: Clear the Encrypt content to protect data check box. Similarly, we should pay attention to the following issues when using decryption: 1. To open Windows Explorer, click Start → Programs → Accessories, and then click Windows Explorer.

2. When decrypting a folder, you will be asked whether to decrypt all files and subfolders in the folder at the same time. If you choose to decrypt only the folder, the encrypted files and subfolders in the folder to be decrypted will remain encrypted.

However, new files and folders created in decrypted folders are not automatically encrypted. The above is how to use file encryption and decryption! In the course of use, we may encounter the following problems, which are explained as follows: 1. Advanced buttons cannot be used. Reason: Encrypted File System (EFS) can only handle files and folders on NTFS file system volumes.

If the file or folder you are trying to encrypt is on a FAT or FAT32 volume, the Advanced button does not appear in the properties of the file or folder. Solution: Use the conversion tool to convert the volume to an NTFS volume.

Open a command prompt. Type: Convert[drive]/fs:ntfs(drive is the letter of the target drive) 2. When the encrypted file is opened, an "Access Denied" message is displayed. Reason: Encrypted File System (EFS) uses a public key certificate to encrypt files, and the private key associated with this certificate is not available on this computer.

Solution: Find the private key of the appropriate certificate, and use the certificate snap-in to import the private key into the computer and use it on this computer. 3. Users are encrypted files based on NTFS, and cannot access the encrypted files after reinstalling the system (note: the encrypted user's certificate must be backed up before reinstalling Win2000/XP): Step 1: Log in to the computer with the encrypted user.

Step 2: Click Start → Run, type mmc, and then click OK. Step 3: On the console menu, click Add/Remove Snap-in, and then click Add.

Step 4: Under a separate snap-in, click Certificates, and then click Add. Step 5: Click "My User Account" and then click "Finish" (as shown in Figure 2, if the non-administrator user is encrypted, this window will not appear, and go directly to the next step).

Step 6: Click Close and then click OK. Step 7: Double-click Certificate-current user, double-click individual, and then double-click certificate.

Step 8: Click on the "expected use" column to display the certificate with the words "encrypted file". Step 9: Right-click the certificate, point to All Tasks, and then click Export.

Step 10: According to the instructions of the certificate export wizard, export the certificate and related private key in PFX file format (Note: it is recommended to export the private key to ensure that the certificate is password-protected to prevent others from stealing. In addition, certificates can only be saved to directories for which you have read and write permissions.

4. Save the certificate and pay attention to save the PFX file. After reinstalling the system in the future, no matter which user, just double-click this certificate file and import this private certificate to access the encrypted folder of the original user of this certificate under NTFS system (note: the encrypted folder on NTFS partition backed up by backup recovery function cannot be restored to non-NTFS partition).

Finally, I would like to mention that this certificate can also be used for the following purposes: (1) granting different users access to encrypted folders, exporting my certificate as an "export private key" and sending it to other users on this computer who need to access this folder. Then he logs in, imports the certificate and realizes the access to this folder.

(2) Access the previously encrypted folder backed up by the "Backup Recovery" program on the WinXP machine. Back up the encrypted folder with the "Backup Recovery" program, and then copy the generated Backup.bkf together with this certificate to another WinXP machine and restore it with the "Backup Recovery" program (note: it can only be restored to NTFS partition). Then import the certificate, and you can access the recovered file.

Win98 Four Ways to Encrypt Folders 1. In the Windows Explorer window, right-click the folder you want to encrypt, click Properties, and then select the Hide check box. Set the key value of "Checkedvalue" under the branch of "HKEY _ local _ machine \ software \ Microsoft \ Windows \ currentversion \ Explorer \ advanced \ folder \ hidden \ showall" in the registry.

How to encrypt files?

It's simple to say, it's encrypted by the system.

Right-click the file to be kept secret = => Select attribute = => Advanced = => "Encrypt content to protect data" = = > Make sure that the file encryption is completed. This encryption method can only be accessed and modified by the currently encrypted user, and other users, even system administrators, cannot access and modify it.

Other encryption methods will use software. If it is text encryption, you can choose to use Notepad to enter the content, then save Notepad as a format, and then open the file and select File = => Save as = => to pop up a dialog box: select the encoding option and select other encoding except Simplified Chinese. Save the file as a. txt file.

Then open it again to see what effect the notepad file you just saved has. .

How to encrypt files in the mobile phone?

The first method is to encrypt with a mobile phone lock.

You have to lock the program that opens the file with your mobile phone lock. You can't open the program without a password, so as to achieve the purpose of file encryption.

The second method is shift encryption.

Just put the files you want to hide in a hidden folder, such as System, so that your files will not be displayed. This method of hiding files is very useful, but finding this hidden file is very annoying. Of course, having a computer is another matter.

The third method is to change the suffix encryption.

Use your own file management to change the suffix names of pictures, videos and sound files, and then the changed files will not appear in multimedia. If you need to see them, just change the suffix name back.

The fourth method is to encrypt with the file lock Best_Crypto.

This software can encrypt files in various folders of mobile phone C/D/E, such as,, sis, 3gp, etc. It is the early encryption software of S60 third edition, and its encryption method is to copy the original file and encrypt it.

The fifth method is to use file force encryption, Y- manager or Q- manager.

Change the properties of the folder to hidden, and then move the files that need to be encrypted to the folder. However, in practice, it is found that files that have been searched in multimedia can still be found in multimedia even after the files are moved to hidden folders. The solution is to change the file name after the file is moved to the hidden folder.

The fifth method is to use telephone wizard to encrypt.

The encryption function of the telephone wizard is extremely powerful, which can encrypt short messages, call records and files. Here I only talk about the method of file encryption: enter the telephone wizard-file manager-enter the password (if the password has not been changed, the default is 123)- find the file to be encrypted-options-encryption (if multiple files are encrypted, mark them first and then encrypt them). The telephone wizard can only encrypt files, not folders. You can use Y- Manager or Q- Manager to view encrypted files, but you can't open them. When decrypting, just enter the file management of the mobile phone wizard, click Options, and then select Decryption.

In order to prevent others from seeing the private files on our mobile phones and bring some unnecessary troubles to our lives, then you can choose to encrypt the private files. The above methods are commonly used and each has its own advantages. If you have other good ways to encrypt mobile phone files, you can also exchange them.

Set the password according to the above two methods. 3. Click Save in the toolbar (or click Save in the File menu). Every time you start Word, you will be prompted to enter your password.

How to encrypt files

If it is a single file such as WORD and EXCEL. , which itself has encryption function. WORD in Tools → Options → Save; EXCEL is located in the general options of the save dialog box.

If there are not many files, you can also copy them into a folder, right-click the folder → Add to compressed file → Advanced → Set password, and delete the source folder after compression.

If there are many files, I suggest you use:

Enterprise information security expert v2.0 Green Edition (with registration machine)

Software size: 700.98KB

Software Language: Simplified Chinese

Software category: portable application/freeware.

Operating environment: Win9X/WinXP/Win2000/

Software Description: This is a special software for encrypting local hard disk and mobile hard disk (or USB flash drive) folders. The software adopts a unique and secure encryption algorithm, which solves the problem that many users who use mobile hard disks need to encrypt the U disk folder urgently. Its main functions are as follows: (1) plus fast mobile encryption: this method is fast, safe and reliable, and it takes less than 3 seconds to encrypt 10G data. Encrypting folders can prevent copying, copying and deletion. After successful encryption, perform "decryption". Exe "file will be generated in the root directory of this folder. When you take the mobile hard disk or USB flash drive to another computer, you only need to run this "decryption". Exe file, enter the correct password, and the folder will be automatically encrypted after the operation. (2) Intensity compression encryption: Compared with fast mobile encryption, the biggest feature of intensity compression encryption is that it can compress and encrypt a folder into an EXE file. Just copy the executable file to another computer and enter the correct password after running, which is extremely safe and has good portability. If you send important confidential files to your friends, you can use this function (hint: the weakness of intensity compression encryption is that it is slow to encrypt folders larger than 100M, so it is recommended to use fast mobile encryption to encrypt large folders). Encryption and decryption operations are very simple, just like fast mobile encryption, just select "strength compression encryption" in the window below. (3) Hard disk encryption and system security settings: This function can lock and protect the hard disk, provide double insurance for your computer, and solve your worries.
