Our focus on privacy means we do not want any unencrypted data sent to our servers. Proton Drive decrypts files locally and doesn’t have access to your data This simply does not meet Proton’s standard for privacy. This system, while efficient and direct, requires the server to be able to decrypt your files. In this example, your cloud storage service’s backend server does most of the work. The backend server finds the files, creates an archive (if needed), and sends everything back to your browser as a file download.Have the frontend client, such as your browser, initiate a request and have the backend server deal with it.The simplest way to fetch an encrypted file is to: This brings us to your standard cloud storage service. Instead of being able to use the massive amounts of memory and computational power of a server in a data center, the application is bound by the amount of memory, features, and computational power of the device it’s running on.Ĭurrent app development is a balancing act between what tasks the server will handle and what tasks the client (or app) will handle. While this allows for more functionality, it comes with a downside. In the early days of the internet, servers handled the vast majority of the “work” (data processing, encryption, etc.), and web apps did relatively little beyond relaying information to the user.Īs the internet developed, applications became more complex and handled more of the processing themselves on the user’s devices. How other cloud storage services download your filesīefore we can explain how Proton Drive downloads your files, we’ll need to look at how most cloud storage services download files. In this article, we explain how Proton Drive downloads your files so that you receive them quickly while making sure your information remains private and encrypted, even from us. This approach also means we often have to create entire new frameworks to handle what otherwise might seem like a simple function. This is a radically different approach to most Big Tech offerings, where data collection is the true purpose of the service. Whenever we develop a service, our goal is to make sure it does not leak or expose any of your information at any time to anyone, including ourselves.
