This week’s open source software highlight is Cryptomator. It is a unique free open source encryption software that allows you to encrypt data before uploading it to the cloud.
There are several cloud services available for Linux, and almost all cloud services do not provide End-to-end encryption, At least not by default.
Usually, the connection between the device and the server is secure. But the data you store on the server is not encrypted. Employees who directly access your cloud service provider’s infrastructure can access this data.
Of course, these companies have strict policies for such intrusions, but rogue employees can cause great losses. Remember when the event occurs Outgoing Twitter employee deactivates US President Donald Trump’s account.
If you are one of those who are cautious about privacy, you want to simplify cloud storage, but increase the security of encrypted storage.
Now some Services like pCloud do provide end-to-end encryption But this requires an additional fee. If you can afford it, great. If not, you can use free open source tools, such as Cipher.
Cryptomator helps you protect data by encrypting it before uploading it to any cloud storage service. In this article, I will focus on the main functions of Cryptomator and instructions for use.
Encryptor: add an encryption layer to your cloud data
Cryptomator is a solution to encrypt data locally before uploading it to the cloud.
This way, you can create a vault locally and sync it to the cloud storage service you use.
It’s very easy to use, and you don’t need to have any specific technical knowledge to encrypt data-this is what Cryptomator is tailored for you.
Cryptomator is a simple encryption tool with basic functions. It provides:
- AES And 256-bit file encryption.
- Ability to create vaults and synchronize them with cloud storage services
- Optional recovery key for the vault master password
- Cross-platform support (Linux, Windows, macOS, Android and iOS)
- Support one-time use of dark theme.
- stand by WebDAV, fusewith Dokany Easy integration with your operating system.
caution Android system with IOS The application is a paid application, you must purchase it separately, and the desktop program is completely free to use. In addition, you need to purchase a one-time license to unlock the dark mode. Please don’t blame them. They need to make money to develop this open source software.
Cryptomater provides an AppImage file that you can download to get started on any Linux distribution.
You can get it from it Official download page. If you do n’t know, read how to use AppImage files to get started.
Encryption is a double-edged sword. It can protect you and may harm you. If you are encrypting data and forget the encryption key, you will always lose access to the data. Cryptomator provides a recovery key option, so use your password and recovery key with caution. Don’t forget it or lose the recovery key.
After installing Cryptomator, you can follow the user interface or Official documents.
However, to save you time, I will highlight some important things you should know:
After starting Cryptomator, you need to create a file library where you want to store encrypted data.
Depending on your requirements, it can be an existing location or a new custom directory.
Now that you continue to create a new vault, you will also observe that you can also open an existing vault (if it already exists). So, just in case, please always back up your vault.
Here, I assume that you are a new user. So, obviously, continue to create a new vault and name it:
Next, you need to specify a storage location. If you have used OneDrive, Dropbox, Google Drive or similar tools, it may automatically detect it.
However, if this is not the case (for example, I use pCloud), you can manually select the cloud sync directory or any other custom location.
After selecting the location, you only need to create a password for it. It is best to create a strong password that is easy to remember.
Also, I suggest you choose to restore the key and store it in a separate USB drive, or just print it on paper.
That’s it. You have finished creating a safe vault that can be synchronized with the cloud.
Now, how to add files to it? Let’s see:
note: Not only can you enter the folder created from the file manager, but you can also find the files there. Follow the steps below to properly add files to the encrypted vault.
After creating the file library, you only need to enter the password to unlock it, as shown in the following figure. If you are using a personal computer, you can choose to save the password instead of entering the password each time you access the vault. However, I recommend against this. Entering the password manually helps memorize.
Next, after unlocking the vault, you simply click “Show library“Or display the drive to use to open it File manager The location where you can access / modify or add files.
You only need to copy and paste the created folder to another location other than the USB drive or cloud storage folder to ensure you have a backup of Vault.
The important thing is masterkey.cryptomator To open the file library file.
You should enable the automatic update feature to ensure that you will automatically have the most stable and error-free version.
In addition to the most important functions of the Cryptomator application, you can adjust some other functions, such as:
- Change the type of your virtual drive
- Adjust the vault to read-only mode
You can explore Safe deposit box options And settings on Cryptomator to understand what else you can do.
Now that you know Cryptomator, you can easily encrypt important data locally and then upload it to the cloud.
