The Challenge of Password Protected Text File
Password-protected text file can be a tough nut to crack, especially if you’ve lost or forgotten the password. Unfortunately, there is no default option to open or access a password-protected text file without entering the password. A password-protected file is encrypted and only the correct password can decrypt it, making it unreadable and inaccessible. However, there are several methods that can help you get through this challenge, as long as you have a bit of technical knowledge.
Things You Should Prepare for
Before we dive into the methods, there are some important things that you should prepare for. The first and foremost thing is to make sure that you are authorized to access or view the encrypted file. If you’ve lost the password, you must note that resetting the password can be a lengthy process.
You will need a lot of patience and time to successfully retrieve the password or break the encryption. Also, some of the methods might require additional software or tools, so make sure to go through each method properly before proceeding.
Method 1: Use Notepad
Notepad is a simple and quick solution if the password protection on the text file is weak. This method works only if the file is password protected and not encrypted using a strong algorithm. Follow the steps below:
1. Open the password-protected text file in Notepad.
2. Select the text that is being used as a password on the file.
3. Press "Ctrl+C" or "Right-click" and select "Copy".
4. Open a new Notepad document.
5. Paste the copied text in the new document.
6. Save the new document with a ".txt" extension as the file format for readability.
7. Open the new document, this time without a password.
Pros:
– Quick and easy solution.
– No additional software or tool is required.
Cons:
– Works only if the password protection is weak.
– Cannot work if the file is encrypted with a strong algorithm.
Method 2: Use a Text Editor
If Notepad is not working, you can try using a more advanced text editor. Sublime Text is a popular text editor that can be used to open password-protected text files. Follow the steps below:
1. Download and install the Sublime Text editor on your computer.
2. Open the password-protected text file with Sublime Text.
3. Select the password section of the file.
4. Right-click and select "Copy".
5. Open a new document on Sublime Text.
6. Paste the copied password in the new document and save it with a different name.
7. Right-click on the saved file and select "Open in Hex Editor".
8. Once it’s open, search for "þ7z¼".
9. Change the value from "þ7z¼" to "7777777".
10. Save the changes and close the Hex Editor.
11. Double-click on the new file you created to open it without a password.
Pros:
– Works on more advanced passwords that Notepad cannot handle.
– No additional software or tool is required, except for Sublime Text and a hex editor.
Cons:
– Takes longer than Method 1.
– Not guaranteed to work on heavily encrypted file formats.
Method 3: Use Online Decryption Tools
If you’re looking for an online solution, there are multiple online decryption tools available. Follow the steps below:
1. Search for an online tool such as Recoverit or Passper for PDF.
2. Upload the encrypted text file.
3. Follow the instructions provided in the online tool to decrypt the file.
4. Once the file is decrypted, it can be opened and read.
Pros:
– No need for technical knowledge.
– No software installation required.
Cons:
– Cannot be used if the content that you want to encrypt is too large.
– Data leakage risk is high if the online platform is not trusted.
Method 4: Use CMD
If you are not comfortable with online tools or downloading an additional editor, CMD can be used as a workaround. Follow the steps below:
1. Press "Win+R" key and type "cmd" in the "Run" box.
2. In the CMD window, navigate to the directory where the password-protected file is saved.
3. Run the following command "notepad file_name.txt".
4. This will open the file in Notepad. Copy the password section of the file.
5. Close the file without saving it.
6. Open a new Notepad document.
7. Paste the extracted password in the new document. Save the file with a ".txt" extension.
8. Return to the CMD window and run the following command "cipher /u /n /h /r:filename.txt".
9. This will decrypt the file using the key extracted from the password section.
Pros:
– No need for any additional software.
– Works on most encryption types.
Cons:
– May not work if the encryption type is highly complex.
– Requires basic knowledge of CMD commands.
