scp pasword in a script

I want to use scp to copy files from a cron job from one linux to another linux. I notice that the scp does not have a "batch" option. Is there a way to get scp to copy files without asking for a password?

By using public and private keys you can ssh, scp and rcp without the need for entering passwords. "man ssh" for more info.

I think the easiest way would be to use RSA/DSA keys stored in $ClientHome/.ssh/[ida_dsa/id_rsa] which are compared to $RemoteHome/.ssh/authorized_keys when connecting. If all is well you should just be able to pass the command: $ scp /path/to/foobar username@hostname which will copy the file foobar to the user's home directory on the remote server without asking for a pasword.
