  4. Enter your desired password and click ‘OK’.
  5. Click ‘OK’ again to complete the RAR file creation process.

Pros:

  • Easy to use.
  • RAR format is widely supported in most operating systems.
  • File size is compressed during encryption.

Cons:

  • WinRAR is not a free software.
  • If you forget your password, you cannot recover the file.
  • Files can only be accessed by people who have the password.

Method 2: 7-Zip Encryption

7-Zip is a free file archiving tool which also supports password-based encryption. Here’s how you can use 7-Zip to lock your text file:

  1. Download and Install 7-Zip software from the official website.
  2. Right-click on your text file and select ‘7-Zip’ > ‘Add to Archive’.
  3. In the Archive name field, rename the file with .7z extension (e.g. newfile.7z).

Why Can’t I lock A Text File with Password?

If you are having trouble while locking your text file with a password, there could be several reasons:

1. Not Using The Correct Method

Make sure you are using the method that is suitable for your operating system and file format.

2. Incorrect Password

It is important to use a strong password and avoid using common words and phrases. If you have forgotten your password, you may not be able to unlock the file.

3. Software Compatibility

Encryption software may not be compatible with all operating systems. Check the software manual to ensure compatibility with your operating system.

Fixes

1. Use The Correct Method

Research the methods carefully and choose the one that is compatible with your operating system and file format.

2. Use Strong Passwords

Always use strong passwords that contain at least eight characters, including uppercase and lowercase letters, numbers, and special characters.

3. Check Software Compatibility

You should check the software manual to ensure compatibility with your operating system.

Implications and Recommendations

Encryption is a powerful tool that helps you protect confidential information from unwanted access. Password-protected text files ensure that only authorized users can access the data. However, it is important to use strong passwords and choose the encryption method that best suits your needs. We recommend using a password manager to create and manage your passwords, as this ensures the security of the password itself.
