ed25519 keys still don't work #159

Closed prpr19xx closed 2 years ago

As detailed in #136, ed25519 keys still don't work with 2022.82 I generated a key in openssh format, converted it to dropbear format and back again and the result is different:

The result isn't expected to be identical - OpenSSH keys have 8 bytes checkint that will differ. Testing here an OpenSSH key converted to use with dbclient works successfully. What steps fail for you?

Apologies for the confusion on my part. Connections work successfully. I was previously unaware of the expected difference in the keys.
