A patch for ssh

This patch adds a program called snk and a configuration option called SNKFile to openssh-3.2.3p1. snk computes responses to chalanges and manages files that store your SNK key encrypted with DES. To use it with ssh simply create the keyfile with snk and add "SNKFile <the_file>" to your config file.

To apply the patch, download it and run this in the openssh source tree.

$ patch </path/to/the/patch

After that you can build ssh just as you normally would.
