Subject: [PATCH] upstream: When signing certificates with an RSA key, default
to
using the rsa-sha2-512 signature algorithm. Certificates signed by RSA keys
will therefore be incompatible with OpenSSH < 7.2 unless the default is
overridden.
Document the ability of the ssh-keygen -t flag to override the
signature algorithm when signing certificates, and the new default.
