there's also resilio sync that gives you the option have the node/folder on your vps be encrypted. hopefully syncthing will add that feature at some point in the future
I have been considering spending more money than I should finding someone on a freelancer site to add the untrusted node / encrypted file transfer but don't give a certain node the key to decrypt the file support, that is the number one missing feature for syncthing for me.
It would unlock scenarios like share your files with me and I'll share files with you and neither of us will know the others files unless your house burns down in which case you can get your files back just by hookin the sync back up with the encryption key pulled from your password manager.
