ssh is not support in macos

[jadeydi]

import ssh from 'ed25519-keygen/ssh';
...

I used the example, to generate a ssh private & public, for macos there will be an error

-> % ssh-add id_ed25519
Error loading key "id_ed25519": invalid format

It's valid. You are doing something wrong. I've just tested it by doing ssh -i ./id user@hostname

For people like me and @jadeydi, I think I found the issue:
On macOS the last line should be a new blank line

Example that give you an invalid format:

-----BEGIN OPENSSH PRIVATE KEY-----\nb3...EBQ==\n-----END OPENSSH PRIVATE KEY-----

Example that works

-----BEGIN OPENSSH PRIVATE KEY-----\nb3...EBQ==\n-----END OPENSSH PRIVATE KEY-----\n

@jitbasemartin I don't see a problem. The output clearly has \n. Maybe you are copy-pasting it?

> require('./ssh').getKeys(new Uint8Array(32).fill(2)).privateKey
'-----BEGIN OPENSSH PRIVATE KEY-----\n' +
  '\n' +

Thank you @paulmillr for the investigation. I confirm I did a copy paste, this is why.
