Zero-Knowledge Encryption Cloud Storage: What’s the hype about?

When it comes to cloud storage security, we all look for private cloud storage or end-to-end encryption on our data.

After all, we all would like to know how our files can be safe in cloud storage.

That’s why we’ve come out with the most secure cloud storage in the first place.

But, what happens if those files are leaked or hacked?

What happens when authorities show up to your provider’s offices with a warrant?

Your data are exposed when it comes to these situations.

Therefore, it is imperative that your cloud storage is secured.

While the top cloud storage providers do go all out to ensure that your files are safe, they can’t provide 100% security on your data.

For that very reason, it is time to know more about zero-knowledge encryption.

All You Need to Know About Zero-Knowledge Encryption?


Zero-knowledge encryption also known as private encryption is a type of security where cloud storage providers never store your login credentials in their servers.

In other words, they can never find out your password. It is one of the ultimate ways to keep your data private.

Though, if you ever lose your password, it is gone forever. So, make sure never to forget your password.

Essentially, a zero-knowledge cloud means that all data is encrypted and anonymized so that even the cloud provider doesn’t know what’s inside your data. It’s important because you don’t want a cloud provider or anyone else to know what you’re storing in your data.

The concept of a zero-knowledge cloud becomes even more important when it comes to digital signatures.

A zero-knowledge cloud is a cloud of encrypted data that is made available to a group of people. In order to access the data, each member of the group must present a unique key that is used to unlock their individual data.

Without a way for the provider to verify that you really own the files you’re storing, you can end up storing data whose authenticity is completely up to someone else (including the provider), potentially allowing other parties to invalidate your code or data.

The “Zero-Knowledge” encryption protocol is a file storage security measure that doesn’t rely on either end-user or admin authentication to verify the validity of stored data. The benefit of this method is that only the intended recipient can decrypt data, even if a hacker were to gain access to the files.

No third-parties (and certainly not the providers like Google, Dropbox, etc) are permitted access to the data stored by your chosen provider.

The limitation of zero-knowledge cloud storage to only storing data owned by you is an important security principle that companies take precautions to implement to provide continued value for their customers.

How does zero-knowledge encryption work?

Glad, you asked!

Most cloud providers retain user login information by giving you access to enter into your account in case you forget or lose your password.

One of the most common ways in recovering your password is typically performed with a question-answer setup.

You, basically enter your pre-selected answer to your chosen pre-selected question, and you get to reset your password.

Typically, this kind of method leaves the door wide open to hackers or others that would want to access your account.

Sounds dangerous, right?

With zero-knowledge encryption, your files are protected as well as your login information.

As previously mentioned, no one knows your login information except you.

You have the pilot seat over your login credentials.

Moreover, these zero-knowledge encryptions will never trace your information, store cookies, and meta tags.

Additionally, only you can access your data because you and only you hold the keys to decrypt it.

Advantages of using zero-knowledge cloud storage:

  • Highest plausible control over your files & data
  • The ability to use the most convenient and user-friendly cloud storages with the uppermost security
  • Highest safety from data breaches and data privacy
  • No need to trust your provider except for the physical protection and storage of your files & data

Disadvantages of using zero-knowledge cloud storage:

  • If you forget your password, you can never access it again, or your data is lost.
  • Some require additional charges and it’s not free.

Which cloud storage providers provide zero-knowledge encryption?

Now that the information about zero-knowledge encryption is out of the way, let’s get to the important stuff!

As you probably know by now, most cloud storage providers do not offer zero-knowledge encryption technology as part of their free or standard plan.

In fact, most cloud storage providers don’t provide it. Not even when you are ready to pay for it.

They furnish users convenience in favor of protection and security.

What’s more surprising is that some of the dodgy cloud storage providers do not even have decent security features for their services!

But not to fret!

When is it appropriate to use zero-knowledge storage?

If your data isn’t sensitive, or you don’t have any regulations to adhere to, then you probably don’t need to use a zero-knowledge solution.

You can store your files on the cloud using any of the existing providers out there, like Box, Google Drive, Dropbox, iCloud, or any of those offering free cloud storage.

This article focuses only on the zero-knowledge cloud storage solutions that allow advanced encryption capabilities such as the ones offered by pCloud and Tresorit — encrypted local storage.

If you can’t trust your data in the hands of others, a NAS might be your final choice.

Zero-knowledge encryption means that your data and files are going to be more secure than Dropbox or Google Drive.

This would be the most effective way to prevent hackers, and since hackers tend to target cloud storage providers, it is strongly recommended to select one that offers this secured feature.

But it would be great if you know how encryption works to protect our data.

The privacy of your data is your responsibility at the end of the day.

It is up to you how and where you want to store your data.

After all, zero-knowledge encryption keeps your data like a fortress of privacy.

Even if you’re slightly a bit hesitant about the prices, don’t be – the cloud storage mentioned above is affordable, and some are free, which makes this storage a choice for a no-brainer. is a very affordable zero-knowledge cloud backup for their 100% private end-to-end encryption.

“Your data security is your responsibility, and safe, private cloud storage should be a high priority for everyone where data is the new currency today”.
