This is interesting, but shows some of the problems with the word "secure"

The app. promises to be more secure than OpenSSH and provides a number of reasons why it thinks it will be.

However the site is entirely anonymous, so you have no idea who wrote this tool and what their affiliations or background are. So either you audit the code to get some assurance, or you trust the author(s) without any evidence.

Also the lack of any form of signed binaries would make me a little nervous from a security focused tool. You're then not only trusting the author(s) but their web hosting providers as anyone with access to that webserver can change the binary without it being obvious that they have.
