I'm trying to get Matthew Wall's sftp extension working with weeex 3.9.2 on my Raspberry Pi 4.0. It's a patched up to date version of Raspbian, but I get the following error on upload to an sftp server:

I am using Ed25519 elliptic curve cryptography that I thought should work. I'd use regular RSA, but the "guy on the other end" wants Ed25519. Should this work, or is it limited to RSA/DSA cryptography? Or . . . am I missing something else?
