RTFM ;-). `man ssh' describes how you can copy your public key to
your ~/.ssh/authorized_keys file on the remote host.
Unless you can physically guarantee that your public key cannot be
compromised, I would strongly urge you to protect it with a pass
phrase (which you were asked to enter when creating the key with
ssh-keygen).
Now, if you use a pass phrase, you have to enter it each time you
use your private key, which is what you would have to do when using
scp. What the other folks didn't mention is that you should then
ensure that ssh-agent is running so that you can run `ssh-add,'
enter your pass phrase, and not have to be asked for your pass
phrase again during that session.
Note that Debian/Gnome/X installations start ssh-agent for you.
However, if $SSH_AGENT_PID is not defined, you can start it yourself
like this:
$ exec ssh-agent bash
This runs a bash shell under the ssh-agent. As described above, use
ssh-add to enter your pass phrase for the session, and then scp
away.
You can then run `ssh-add -d' to forget your passphrase, which you
should do when leaving your terminal in a public environment.
