If you are concerned about security you should NOT use FTP, as FTP
authentication is based on a clear-text protocol, i. e. it will
transmit your password in plain text over the network.  Anyone able
to run a sniffer anywhere on this net will be able to see it.

This probably makes more sense - especially, as it's already supported
in mainline U-Boot - assuming you have good ways to manage your keys
on your device.

Best regards,
