Cryptomator: create a secure vault for your files

Reading time: 2 – 2 minutes

Yesterday I found a tool called Cryptomator, this is a client-side encryption for your files. You can use it with Dropbox, or any other cloud filesystem or you can use it in your local filesystem. Anyway, this open-source piece of software is really simple to install and is compatible with Windows, Mac and Linux. Once this is installed, using the UI the only thing we have to do is create, or select, a folder where the secure vault is going to be created. It uses a symmetric password for cyphering and when the vault is unlocked a new removable drive appear in your system. So, at the end, the vault is like a pendrive and there is no complexity on add, rename, remove, create folders, etc. inside the new drive. Once the vault is locked, the removable drive is unmounted and if you go to the location where the vault is created a tree structure with cyphered files is the only thing that you can see. Cryptomator works cyphering each file, not the complete vault as a package.

So far I installed the tool on my Windows computer for securing some sensitive files that I have on my laptop. But if it works like I expect I’m going to extend the usage with the rest of my computers. As I said it’s not required any cloud filesystem, by the way, I use Cryptomator in conjunction with Resilio Sync.
