I wasn't commenting on the strength of RSA-1024, per se, but on the assumed age of that key. OpenSSH's ssh-keygen hasn't defaulted to 1024 bit RSA keys since before version 4.2, in 2005. (I had to look it up: https://www.openssh.com/releasenotes.html https://www.openssh.com/releasenotes.html) You can still generate a 1024 bit RSA key, but someone would have to go out of their way to do so, and I can't imagine why they would have done that in the past .. decade?
