Adding an extra layer of protection is essential to avoid theft especially on your personal files saved on a computer. Encryption allows you to password protect any file or folders inside your device to ensure that no one steals your private information. Learn how to encrypt files on Mac in this brand new post.
We all have files saved on our Mac that we don’t want other people to see or gain access to; these files may include your bank details, personal records, and other important notes. Good thing we can easily encrypt these files on Mac using the Disk Utility.
Although we can use FileVault, which is full-disk encryption that prevents unauthorized access to the information on your startup disk, we could feel safer when we also encrypt specific files or folders most especially when we are sharing computers with someone else.
How to encrypt files on Mac? We will use Disk Utility and set a layer of protection by adding a password.
You can now find the encrypted disk image inside the folder location you have set earlier as a DMG file with the filename you have also entered. You can now delete the old file or folders without the encryption. Before you delete the old file or folder, make sure you have created a backup in case you messed up somewhere in the process.
In order to access or open the encrypted disk image, you simply need to double-click on the disk image file and enter the password and click OK. Note that you don’t need to tick the box below to remember the password in keychain otherwise, it just voids all the process we did especially when other users have access to your keychain. After entering the correct password, the disk will be mounted and the files will appear and will be now accessible.
Like we mentioned earlier, FileVault is a special encryption setting provided on your Mac to ensure that you get full disk protection which uses XTS-AES-128 encryption with a 256-bit key.
If you have multiple users on a Mac, each user should also need to enter a password for them to be able to unlock the disk. The encryption takes a while since it is using a more secure key however, you can continue working on your Mac. It continues the encryption on the background and only when the Mac is awake and plugged in.
After the encryption is completed, restart the device and enter the password you have created earlier. You will need to do this every time you log in to your Mac on startup. All users are required to enter their own passwords.
If in any case, you may want to turn off the FileVault, simply go back to Security & Privacy> Find and click FileVault> Click the lock icon and enter the Admin user and password> Click Turn off FileVault. Decryption process also takes a while before it will be completed.
What will happen if you have forgotten your FileVault password? There are three ways you can choose to reset the password.
If you only want to encrypt a single file, well you can also take advantage of the Print to PDF option. We assume everyone is familiar with this option. Any files which allow you to print to PDF can be encrypted. Check these steps below:
That’s it! You have practically encrypted a PDF document. You can do this for your personal notes and other single file or documents.
There you have it, we have finally learned how to encrypt files on Mac using Disk Utility as well as encrypting the entire disk using FileVault. However, using FileVault might consume or take much space on your drive and may cause latency or poor device performance.
