Please try to configure your email client so that it performs word
wrapping at around 72-78 characters. Thank you.

Pretty secure, IMO.

If you connect for the first time over a trusted network (say, over your
own LAN), then that's no problem. The SSH client (putty) caches the
server key somewhere on the disk, and since the LAN is trusted, you know
it's the correct key. From then on, you can just go ahead and connect.

OTOH, if putty tells you after a while that the server key changed, that
may be a sign of a man-in-the-middle attack.
However, that's pretty rare, usually it's just someone who reinstalled
the OS on the server. :-)

no

Yes, openssh was probably smart enough to figure that out itself.

OTOH, if you don't have special requirements, you can just use the
binary OpenSSH package provided by your distribution, no compilation
required. In the overwhelming majority of cases, that's all you'll ever
need.
