SyncThing – it is possible to set a password on a folder when it’s shared with another device so data sent will be encrypted by this password and data received will be decrypted by the same password
To do that there is a command to convert the encrypted data to plaintext on disk meaning you should only do that on a trusted device to decrypt the data run the following command pointed at the root of the encrypted folder
C:\PC_TOOLS\syncthing-windows-amd64-v1.27.6\syncthing.exe decrypt –to C:\FolderSyncThingDecrypt –password <password> C:\FolderSyncThingEncrypt
