Comment (by dkocher):

 > ssh-keygen(1): write OpenSSH format private keys by default instead of
 using OpenSSL's PEM format. The OpenSSH format,
 supported in OpenSSH releases since 2014 and described in the PROTOCOL.key
 file in the source distribution, offers substantially
 better protection against offline password guessing and supports key
 comments in private keys. If necessary, it is possible to write
 old PEM-style keys by adding "-m PEM" to ssh-keygen's arguments when
 generating or updating a key.
