We talked to Andrea Pfundmeier from Boxcryptor about End-to-End-Encryption
August 21, 2017

Who are you and what do you do?

My name is Andrea and I am CEO and one of the founders of Boxcryptor. Together with my co-founder and our CTO Robert we started Boxcryptor back in 2011. We and our team are located in Augsburg, Germany.

What is Boxcryptor and what is it most useful for?

Boxcryptor in an end-to-end-encryption software optimized for cloud storage. Users of Dropbox, Google Drive, Microsoft OneDrive and many other storage providers (and of course ownCloud users) can use Boxcryptor to encrypt and protect their data. We started Boxcryptor because we wanted to use Dropbox and add encryption without giving up the cloud advantages: We still wanted to be able to share files with others and access them on all our devices. Back in 2010, there was no encryption software available on the market which could fulfill these requirements. Therefore we developed our own solution and Boxcryptor was born. Boxcryptor encrypts the data on the local device before the files are uploaded to a cloud of your choice. What’s most important for us: We want everybody to be able to use encryption even if they are no IT experts. Therefore we focus not only on the security aspects, but also on usability.

Against which threat model does Boxcryptor protect me?

Users often ask us, if Boxcryptor protects them against the NSA. Well, 100% security can never be guaranteed. And of course we don’t know what happens behind closed doors at the NSA. But if your use case is to protect your company’s sensitive information (e.g. HR data, sales insights, client data) against internal and external threats, Boxcryptor is the tool of choice. If you want to make sure that your personal data like you insurance details, health data or financial documents are safe, Boxcryptor adds the security you need without limiting you to any storage provider or a certain device. Clients from more than 190 countries already rely on our security made-in-Germany and add security to their clouds.

Why have you decided against an open source business model?

There are good reason for and against being open source for a company. We just had to decide for one road at some point. One main reason why we decided to keep Boxcryptor closed source is to protect our business model, so we can finance the further development of Boxcryptor, independently from others or donations.

As Boxcryptor is not open source, has your software been audited by an independent party?

Boxcryptor has not been audited yet.

In which direction do you want the Internet to evolve?

For us as security provider, we are curious to see how the general security awareness and knowledge evolves. During the last 6 years, we realized that more and more people really care about their privacy and the security of their data. When we started 6 years ago, we had to explain why there is a need for an encryption software for cloud storage providers. Then there was Snowden and everybody started to realize who important their data is and how easy security gets lost. But there is still along way to go!

Nice, do you have something else to say to the community?

Boxcryptor is available for free in a basic version, so give it a try and let us know what you think! Moreover, if you are interested in security topics, have a look at our blog where we share tips and security insights regularly: https://www.boxcryptor.com/en/blog/

This year‘s FrOSCon was awesome!
August 21, 2017

As we already announced, we have been at the FrOSCon 2017 and had an exciting weekend with the versatile open source community.

When we were still on our way to Bonn, we received the first notice about the ownCloud booth. Cornelius Kölbel from NetKnights had already started building it up with the first roll-up – before we even arrived! He is always sneaking in some nice security stuff, just like that one time when he wrote this guest post about End-to-End-Encryption.

We exchanged experiences with other open source projects, and listened to a lot of talks about what’s new in the world of free and open source software. You can look at them at media.ccc.de, all of them have been recorded.

This set an inspiring foundation for the discussions at our booth. We have spent the weekend talking to a lot of interesting people discussing questions about the ownCloud universe.

Thanks to the FrOSCon orga team for organizing this awesome conference!

They set the bar high for our very own ownCloud Conference, taking place in a month. btw, have you already registered? There will be a lot to learn about what else ownCloud is capable of! See you in September!

ownCloud is a very diverse software and rich in opportunities. It can be used under very different circumstances and does far more than only file sync & share, if you combine the right apps. To make the most of your ownCloud it is good to know every aspect of it.

Cornelius Wachinger’s workshop “ownCloud 101 – the essentials” at the ownCloud Conference 2017 covers all the best practices, prerequisites and architecture recommendations you can use to get the best out of ownCloud. At work, Cornelius has to find solutions for very different situations and has a lot of experience with production environments.

In this workshop, he shares his experience with the community. Come to the workshop and learn all of it.

If you are a Microsponsor, you can also get a special certificate for completing the workshop. Have you already considered a community microsponsorship?

We need testers for an important linux client update!
August 10, 2017


Our Community is making progress with the linux client, as we adapt to better foundations. With the move from the system‘s Qt to shipping our own qt5.6.2, the client will rely on less unpredictable libraries in the future. This will fix a lot of underlying problems we had to work around in the past.

But this big step has to be accompanied by extended testing, so we can assure, that no one will end up with broken software. For this, we need your help.

Download the release candidate, install it on a virtual testing environment, and check if everything works after your liking – and if something breaks, report the bug back to us. Only this way we can ensure, that everyone has nice software at the end of the day.

We also fixed an issue with big file uploading and oC 10.x, you can take a look at the full changelog here. Discuss this release on Central.

Thanks for your contribution!
