Finally, depending on the software you use to access or edit the file, it’s possible that temporary copies might be created in unencrypted locations.įinally, make sure you back up your files regularly. In addition, simple deletion of that unencrypted file might not be enough - undelete utilities might be able to recover it. If you’ve copied the file to an unencrypted location on your machine, it’s available to anyone with access. Second: an encrypted volume does you no good if the files are also elsewhere on your machine. Length matters, so using a multi-word phrase is key to keeping your data secure. This is why we talk about a pass phrase instead of a pass word. If you choose an obvious, short, or otherwise easy-to-guess passphrase, an attack can certainly unlock your encrypted volume. There are a couple of important caveats to encrypting your data using tools like VeraCrypt.įirst, encryption does not make a bad passphrase more secure. In cloud storage situations, alternatives such as BoxCryptor or Cryptomator - both designed specifically for this cloud storage scenario to encrypt files individually - may be more viable. If you have a large container (and a slow internet connection), that can become quite the burden. If you place your VeraCrypt container into a cloud storage folder (such as Dropbox, OneDrive, or others), even the smallest change taking place within the container will cause the entire container to be uploaded when it’s unmounted. When one file within the container changes, the entire container is considered to have changed. A VeraCrypt container is a single file on your hard disk that contains all the individual files you’ve elected to store within it. VeraCrypt containers are what I refer to as “monolithic”.

Personally, I tend to use OS-specific whole-drive encryption for my portable devices, but would use VeraCrypt containers for collections of data that need to be secured, particularly if those collections need to be copied from machine to machine. You can elect to mount a VeraCrypt volume only when needed, thus limiting the amount of time the data is accessible in its unencrypted form.

This extends to your other Windows computers, as well as other platforms, including Macs and machines running Linux. VeraCrypt containers can be copied to, opened, and mounted on any device that supports VeraCrypt. In my opinion, container encryption has two advantages over whole-drive encryption: Once the drive is unmounted, the data is once again unrecoverable without knowing the passphrase. Reading from and writing to that drive transparently decrypts and encrypts the data. You then “ mount” that container file using VeraCrypt with the correct passphrase. The contents of that file appear as another drive on your system. Using this approach, you create a single file on your computer’s hard drive that is encrypted. Once your machine is turned off, the data is unrecoverable if the user doesn’t know the passphrase. Once running, data is transparently encrypted and decrypted as it travels to and from the disk. Using VeraCrypt, you can encrypt your entire hard disk, including the boot partition. You supply your passphrase to enable decryption in order to boot. There are two approaches to using VeraCrypt. And yes - the vulnerabilities are fixed in VeraCrypt. VeraCrypt is a free, compatible, supported alternative, based on a fork (copy) of the original TrueCrypt code. In 2015, it was reported that a serious security vulnerability had been discovered in TrueCrypt. With TrueCrypt development halted, there’s no fix forthcoming. TrueCrypt development was abruptly and somewhat mysteriously halted in 2014. Indeed, this article is based on an earlier article specifically about TrueCryp t.

Everything described below applies to both. VeraCrypt is based on, and the heir-apparent to, the exceptionally popular TrueCrypt. VeraCrypt makes encryption not only easy, but nearly un-crackable.

The concern is that someone might gain access to sensitive data.Įven if your device falls into the wrong hands, proper encryption renders that access useless. People are concerned about privacy as well as identity and data theft, particularly on computers or portable devices where they don’t always have total physical control of the media. Encryption comes up frequently in many of my answers.
