Encryption utilities are a special niche for the paranoid. Not everyone is willing to waste time on this kind of data protection. In this post, I will introduce several applications that automate this task.
I want to say right away that we will talk specifically about encryption when working with cloud storages like Google Drive and Dropbox. Therefore, in this post you will not find VeraCrypt and similar utilities. Also, there will be no cloud storage, which natively supports End-to-End encryption.
Boxcryptor (Windows, macOS, Linux, Android, iOS)
I talked about Boxcryptor in a separate review. To encrypt data, you will need to connect one or more cloud storages, and then simply transfer the file to the application.
On the site, I have not found anywhere exactly how information is encrypted, except that it is End-to-End encryption.
Cryptomator (Windows, macOS, Linux, Android, iOS)
Cryptomator encrypts files and their names using AES round-trip encryption and a 256-bit key.
The application creates a folder with a password that participates in encryption. All files in this folder are automatically encrypted before being sent to the cloud. When such a folder is accessed on the system, it is mounted as an external USB drive. Dropbox, Google Drive, One Drive, WebDav and local storage are supported.
odrive (Windows, macOS, Linux)
odrive is primarily designed to access popular cloud services through a single interface. However, you have the ability to create encrypted folders with a password, the files in which will be hidden from prying eyes.
Like its counterparts, here End-to-End AES encryption.
Cloudevo (Windows, macOS, Linux, Android, iOS, web)
Like the app above, Cloudevo is primarily needed to combine popular cloud storage. But the issue of encryption comes first here.
All connected services are combined into a Cloudevo virtual disk. All data on this disk is encrypted on the client side by default.
BoxWrap (Windows, macOS)
There is almost nothing to tell about BoxWrap. Nothing is said about the encryption itself on the developer's website. As well as the supported repositories.
It is only clear that when the cloud storage is connected, a virtual disk is created. On it, in turn, all the encryption takes place.
Safebox (Windows, macOS)
The most simple application for encrypting data in Dropbox. The source code is open.
A folder is created on the disk, the data in which is pre-encrypted. And already this folder is sent to Dropbox. Several such folders can be created. At the same time, you do not need to remember any passwords, and everything works without any participation on your part.
CryptSync works in a similar way. But in this case, OneDrive, Google Drive and Dropbox are supported. You can configure synchronization of one folder with several storages at once. The source code is also open.
