The Cryptomator is a simple tool for your digital self defense. Allows you to protect the data you send to in cloud on your own and regardless of the encryption it offers the service you are using.
Most providers in cloud encrypt your data only when you upload it or have the keys to decrypt it if it is stored encrypted. These keys can be stolen, copied or used for reasons you would not like. Here comes the application Cryptomator, so that only you have your data key.
The Cryptomator allows you to access your files from all the devices you have.
How does it protect your data?
To begin with Cryptomator, enter a password for the vault folder in your cloud. That was all. You do not need a complicated key generation process and a lot of settings.
To access the vault, simply use the same password. The folder will open. It is a virtual encrypted drive on which you can move and store your data, just as you would a USB stick. Each time you save something to this disk, the Cryptomator the data will be encrypted automatically.
The encryption technology it uses, as mentioned above, is AES at 256 bits. So if one looks at the folder in in cloud you will not be able to understand what you have saved after encrypted in addition to the data, and the file names.
Is it safe and reliable?
The developers state that there are no backdoors, expiration date and that the application is open source.
This means that you should not blindly trust it Cryptomator, since it is an open source software. For you as a user, it may not mean anything, but those who know can read every line of code to see how the application behaves.
So in addition to independent security checks, the software is constantly and publicly tested in an automated way.
