Cross Platform Question

Our household needs encrypted folders that can be created/unlocked/modified on Windows and macOS. This discussion of Keka for macOS and 7-zip for windows led me to download Keka. On Mac, it works great: creating a zipped folder (and its contents, including other directories) that can be unlocked from Finder by entering password. On Windows, I was sad to see no password asked for to unzip, and all filenames and directory structure visible. Fortunately, the file contents themselves were locked so couldn't be viewed unless dragged into 7-zip and password entered. How do I use Keka to ensure no access to directory data on Windows? Is this possible? And if not, is the restriction Keka-related or Windows related? Thank you very much. Keka looks and feels like a very beautifully designed product.

Please confirm you are using:

1. 7z format
2. Encrypt filenames option
3. AES-256 encryption (not sure if this is required)

Encrypt filenames is not available for .zip format

Thanks, the 7z format wasn't being used (AES-256 was enabled). Couldn't find "encrypt filenames option" until i selected 7z, but then everything works as expected on the windows :-)
One thing that initially confused me was when clicking on this 7z file in finder, it asks for password, but then just keeps re-asking in an endless loop. I guess this is b/c Finder is using its default decompresser (i.e. assuming its .zip, which doesn't support encrypt filenames option).
As it is, I can access Keka compression and decompression using Finder's context menu for item under Services. Alternatively, I could make it the default uncompressor (requires download)
Haven't played around w/Keka Finder extension as I've got the bare minimum of what I need.
I'm very impressed w/the quick response, the documentation, and the general feel of the product.
Thanks!

Great to hear! I'm also a happy user.

@billJelavich the ZIP file structure is not encrypted, that’s why it’s visible without the password. You can use the 7Z format with the “encrypt filenames” but note you’ll need 7-Zip or similar in Windows, since the encryption used (AES256) is not natively supported in Windows.
