I'll like to self nominate GitHub - radumarias/rencfs: An encrypted file system written in Rust that is mounted with FUSE on Linux. It can be used to create encrypted directories
An encrypted file system written in Rust that is mounted with FUSE on Linux. It can be used to create encrypted directories.
You can then safely backup the encrypted directory to an untrusted server without worrying about the data being exposed. You can also store it in any cloud storage like Google Drive, Dropbox, etc. and have it synced across multiple devices.
You can use it as CLI or build your custom FUSE implementation with it.
