Framasoft is using Lufi for their encrypted file-sharing service hosted at framadrop.org.
I filed an RFP for it. Any help with Debian packaging is welcome!
YouTransfer doesn’t do client-side encryption like Lufi. Also, it is currently looking for maintainers.
We tried Filetea and Coquelicot earlier. They were both abandoned by their upstream maintainers. Hence, we had to drop them from FreedomBox as well.
I’m betting on Lufi being maintained since Framasoft is using it in production.
