All About Encrypt and Decrypt Using CMD

There are various ways to encrypt and decrypt files, but in this blog, we’ll focus on using CMD on Windows.

You will understand how to use CMD on Windows to encrypt and decrypt files by the end of this guide.

What are Encryption and Decryption

Encryption and decryption are essential concepts in computer security.

Encryption is the process of converting readable data into unreadable data.

Decryption is the process of converting unreadable data into readable data.

How to encrypt a file using cmd

Encrypting a file using CMD on Windows is simple. The first step is to open the Command Prompt on your Windows computer.

To do this, press the Windows key + R on your keyboard, type “cmd” in the Run box, and press Enter.

Once you have the Command Prompt open, you can use the “cipher” command to encrypt a file. The basic syntax for encrypting a file is:

cipher /E path\to\file

By using the “cipher” command along with the “/E” switch, you can encrypt any file on your computer.

For example, encrypt the “secret.txt” file located on C:\Documents. The code is:

cipher /E C:\Documents\secret.txt

After you run this command, you can see the encrypted file with the “.EFS” extension.

The original file will still exist, but it will be unreadable.

When you encrypt a file, only the person who encrypted the file (and the system) will have access to it.

To share the encrypted file, you have to export and import the encryption certificate. Also, it’s crucial to have a backup plan in case you lose access to your encryption key while using EFS.

In summary, encrypting a file using CMD on Windows is a straightforward process.

How to decrypt encrypted files using cmd

Decrypting a file using CMD on Windows is as easy as encrypting a file.

You will start by opening the Command Prompt, like before. Once you have the Command Prompt open, you can use the “cipher” with the “/D” switch command to decrypt a file. The basic syntax for decrypting a file is:

cipher /D path\to\file

For example, decrypt the “secret.txt.EFS” file located on C:\Documents. The code is:

cipher /D C:\Documents\secret.txt.EFS

Run this command to decrypt the file and restore the original file.

It’s important to note that you can only decrypt a file if you have the encryption certificate for the file. If you don’t have the certificate, you won’t be able to decrypt the file and you’ll see an error message.

you can decrypt any encrypted file on your computer and regain access to the original data.

Conclusion

In conclusion, encrypting and decrypting files on Windows is a breeze with the Command Prompt and the built-in Encrypting File System (EFS) tool. It’s a great way to secure sensitive information and keep it away from prying eyes. So, don’t wait any longer, start encrypting your files today!
