How do I add end to end encryption on my files?

I'm extremely disappointed by Dropbox's handling of the Boxcryptor acquisition. I've been a Dropbox user since 2009 and a paying subscriber since 2014. I've used Boxcryptor for years to secure all of my critical files in Dropbox, and then suddenly I was forced to decrypt all my files before BC went offline last fall. That was a major hassle and it caused me to fall behind on work projects to make the transition.

 

Unfortunately, I've not been able to find an on-the-fly encryption tool like Boxcryptor for PC, so I begrudgingly moved to Cryptomator temporarily, hoping that Dropbox would be true to its word by bringing BC encryption technology to Dropbox by 1Q24. 

 

Well, today marks the end of 1Q24 and it looks like Dropbox Droppedtheball.

CM is a fine tool, but it's riskier than BC: I have to maintain multiple vaults instead of a single login like BC offered. I have lots of encrypted data, so it requires lots of vaults. I now have to be careful to close out of vaults when I'm done and not shut down (or lose power) in the middle of a session without closing out, as opposed to BC which was seamless and virtually invisible once logged in. What's more, I've had syncing issues with CM.

 

So I'm not a happy camper. Dropbox demonstrated lousy customer care by negotiating an acquisition so carelessly that thousands (or hundreds of thousands?) of its customers have had to deal with an as-yet open-ended gap in available zero-knowledge encryption options. It's a real head-scratcher why DB didn't arrange for Boxcryptor to continue to support theirs subscribers for a few more months until this highly-touted technology transfer was complete.

 

I hope Dropbox steps up and offers zero-knowledge encryption to all of its paying customers soon.
