Package: openssh-client
Version: 1:7.1p2-1
When you generate an Ed25519 key, the comment is embedded in the private
key, but there doesn't seem to be a way to change this comment:
$ ssh-keygen -t ed25519 -N '' -C foobar -f tmp
Generating public/private ed25519 key pair.
Your identification has been saved in tmp.
Your public key has been saved in tmp.pub.
The key fingerprint is:
SHA256:...
The key's randomart image is:
...
$ grep -v ^-- tmp | base64 -d | strings | grep foo
foobar
$ ssh-keygen -c -C moobar -f tmp
Comments are only supported for RSA1 keys.
