I agree with Jonatec and Xartrix.
Boxcryptor Portable needs - A LOT - of love from boxcryptor developers.
I am a long-term Boxcryptor supporter and customer. I think that I pay the yearly fee since 2014. Since the beginning, I really liked Boxcryptor and I have encrypted pretty much every file with this tool. However, my appreciation for Boxcryptor is falling rapidly, since I made the decision to transfer from Windows to Linux Mint a few days ago.
What is my issue with Boxcryptor Portable?
I do have a big interest to go out to nature in my spare time and photograph high quality pictures of our world. Therefore, I need a lot of storage for my media content. As a reference point: Currently, I am storing around 50 TB (TB! not GB!) on external harddrives. All my harddrives are encrypted with Boxcryptor. That was fine, until I changed my operating system from Windows to Linux Mint 20.1.
Boxcryptor Portable is horrible to use!
Yes, it is able to connect to my external harddrives and I can - theoretically - decrypt my media content and watch it. However, this is really just theoretical. If I open a small file (like a .txt with 50 KB), it's no problem to double click in the "File Browser" of Boxcryptor Portable. The tool will decrypt the file and show me the content. However - and this is really the big problem - if I want to open a picture or a 4K video (50 MB - 500 MB), Boxcryptor Portable takes very long to open just a single file of this size. It's not seconds - it's minutes! In between, Boxcryptor Portable is "freezing" up. Sometimes, I don't know if the tool is still decrypting the file or I should just kill the process. I also think that Portable is just single-threaded. I think that it just uses 1 of my CPUs to decrypt the files.
So basically, I am not able to use my media content - which I collected over several years - with my new operating system Linux Mint 20.1.
I am even more disappointed from Boxcryptor, because Boxcryptor is first and foremost an IT security / IT privacy company. I changed to Linux, because I wanted to have a more secure operating system compared to Windows. I thought that this would not be a problem at all, because Boxcryptor stands for Security / Privacy and Linux stands for Security / Privacy. I was already disappointed that there is no fully integrated Boxcryptor tool for Linux like for Windows and Apple. I was even more disappointed that the only way to use my encrypted file is this Portable version, which is just crap.
So now I have to go back to Windows to find a solution to decrypt all my 50 TB of data and encrypt it again with a Linux-friendly encryption tool. Thats just ridiculous.
When will be a fully integrated Linux client available? You are a IT security company. You should provide a tool for a secure operation system like Linux.
If you don't plan a fully integerated Linux version, do you plan to upgrade Boxcryptor Portable (very hugh steps are necessary) to be a useable tool for Linux?
