""""""If you click on the download page it comes up with some kind of security page that seems strange.""""

That is your browser warning you that the particular server doesn't have a current security certificate (or response)

You can still download chipp's tool there.

You can also bypass the error message by copying the link then removing the "S" from the https part.

Then your browser wont expect to get a current server security certificate to provide a secure connection.
