Another plus.if you use this method instead of password authentication, no one will be able to crack away at your router trying to guess the password! It functions similar to HTTPS, as all transmissions are encrypted with a key that only the client and server will have. Public key authentication is one of the most secure methods of logging into SSH. Have to be careful that you don't get any line breaks (ie it is one Long continuous line).

Multiple keys can be entered by placing them on separate lines. The DD-WRT firmware can use user/pass logon or only allows connections from clients whose public keys are manually entered via the web interface. Private keys are never exchanged, and are used to decrypt the information encrypted with the associated public key. Your client encrypts information to the server using the servers public key and the server encrypts information sent to you using your public key. For the latter to work, a small public key is given to the server and the server gives your client its public key. SSH operates just as telnet with a user/password combination or on a Public/Private key infastructure. Unless changed, everything SSH operates on port 22. It can also be used for creating secure tunnels, somewhat akin to Virtual Private Networks, and for use as a network file system ( Sshfs). SSH, or Secure Shell, is an encrypted protocol and associated program intended to replace telnet. When asked for the password, enter your router's password (default "admin").When asked for the username, enter root (even if you changed username in web interface).
