Generating ssh key pairs

[Steve Matzura]

In order to use SFTP, I will be needing to generate key pairs for all
my users, all of whom will log into the same directory structure. It
seems no one on the system has keys generated, or they're not in what
I think is the normal place, ~/.ssh - Should I just create this
directory and use ssh-keygen to put the key files there, naming them
appropriately for each FTP user?
