Cloud Encryption between Linux and Windows - Suggestions Wanted and Questions!

Hi there...

I'm looking for a method that is noob friendly to encrypt data that is then mirrored to the cloud.

Basically how these work (or how the ones I have looked at work) is that you have a "vault" that you keep on the synced cloud folder, this contains all the encrpted files, and then you mount that directory as a unencrpted drive for you to work in. Anything you do is encrpted and it is that folder that is shared.

I have found some options, but having a hard time getting them working between windows and linux.I use a ubuntu 18.04 based distro called BodHi.

This is what I would like....

1. Cloud encryption needs to be per file. Many encryption options encrypt the entire directory and its recursive contents into a solid block. If it does that, then any small change to any file or any file added means the entire vault would need to be re-uploaded to the cloud. So w/e method has to support single file encryption of recursive directories.
2. I need a solution that works both on Windows 10 and Linux
3. I am happy to pay for software as long as it is not a subscription fee.

I have found a bunch of options, but I can not get any of them working on both platforms....

1. Cryptomator : Is software designed to do exactly what I am looking for, but I just can not get it to run on linux. The software installs but I can not seem to get the vault to mount.
2. SirKali : Is a front end for a bunch of command line encryption options. I CAN get this working perfectly on Linux, but I can not get it to work in windows. It "seems" to work, but nothing will ever decrypt! SK I think is working fine, it is the command line exe builds of the actual encryption exe that seem to not be working on windows. Also I can not work out how to get this thing to auto mount on application launch. Small quality of life issue but still anoying.

These are the actual encryption apps I know of that work on windows and linux. These all come from the SK Wiki.

• Cryfs : I think this is the literal best option, but the windows version is in beta and the developers warn not to actually use it in any serious way.
• Securefs : This is the 2nd best option and the one I am trying to get working. I just can not seem to get it to run correctly on windows. It runs in a LITE and FULL mode, I tink LITE is the best for cloud but lower security
• Encfs : This is a famous one, and works basically the same as Securefs-lite but less secure (according to google searches). I have not tried this one yet.
• Sshfs : I do not know anything about this one yet.

So that is basically what I know, and what I am trying to find out. If you have any idea of what to do, or anyway to get anything I have talked about actually working. I would be appreciative!

Thanks!
