opacity-electron VS Cryptomator

Another option you can try is to use the Desktop Application. You can download it here: https://github.com/Mavahu/opacity-electron

I'm looking for apps that can manage Opacity. I have recently discovered this community while looking for cloud storage solutions and now I'm trying to figure out if it meets my needs so I can decide whether or not to use it. If I'm not mistaken, Opacity Electron is supposed to be a Windows desktop client for Opacity. However, the official Opacity page on community apps doesn't seem to outline an app for Android, which is a huge letdown.

You're giving some valid criticisms and I have to agree, their webinterface sucks atm. They are aware of it and they're working on an overhaul of the metadata system so these issues will be resolved. The patch will go live next month (according to their AMA). The workaround for now would be using the app. You can find it here: https://github.com/Mavahu/opacity-electron - For me the app works flawlessly and it's a lot faster too! Try it out and let me know what you think. :)

I believe their code is open source so that's a good thing. I'm using their services for a year now and it works pretty well. It also has a strong community support, I'm actually using a community released client atm (which is also open source).

the best way to do this is with https://cryptomator.org

Before putting anything on a cloud service I would recommend 3rd party tools, like Cryptomator, to encrypt folders and such, then upload to a cloud service.

I use Cryptomator - https://cryptomator.org

I've used countless encryption "schemes" over the years, from True/Vera-Crypt to encrypted sparse bundles/images, and none have ever really felt right.

These days i tend to use Cryptomator[0] instead. It accomplishes what none of the others could do, which is transparent encryption across devices.

With Cryptomator, i simply create a vault somewhere in the cloud, stuff data in it, and i can access it from my laptop, phone or tablet, and not think much about it. It integrates into the normal file browsing APIs, and doesn't get in the way.

Because it does "per file" encryption, it also doesn't need to download a 20-100MB chunk from the cloud before decrypting, so it's rather fast (depending on file size of course).

Cryptomator's arguably the most popular encryption software for cloud storage (you can give yourself zero-knowledge encryption by using them) - it's actually what they specialize & focus on (cloud encryption). It's 100% open source and Free to use on computers. On phones I believe it's just a 1-time fee of a few bucks ($13-14, then you have it forever) - note: their iOS offering is still new, so may be a bit unpolished at the moment.

This is the solution: https://cryptomator.org/

Cryptomator. It is made for uploading files securely to cloud storage, but works locally, is easy to use, and completely free for your use case.
