ssh-keysend is a tiny script written in bash which read a number of ssh public keys from a file (according to search pattern) and send these keys to remote hosts (taken from another file, also filtered by specified pattern). The remote host add these keys into authorized_keys file for specified user. Here are an example of use:
$ ssh-keysend bill@gates 10.1.10.*
This example send the key for user bill@gates and send the key to any known_host which match with the pattern 10.1.10.* (yes, it’s a regexp). The key is taken from *.pub files in ~/.ssh/ directory.
You can get the code from launchpad ssh-keysend project page, or get the repository code with bzr:
$ bzr get lp:ssh-keysend
