Generate usable keypair for OpenSSH?

[766F6964]

How can one generate a private-public ECDSA keypair that is in the right
format to be used for OpenSSH authentication? OpenSSH uses its own format
where as the example suggested in the README uses the .pem format that OpenSSH can not understand.
Can someone please show me an example how I can generate a private public ECDSA keypair in a format that OpenSSH can understand?

if to_pem() does not work, then that will require support for new format

Yeah, support for OpenSSH would be great.
Right now working with keys in the OpenSSH format does not seem to be possible.
