How to easily try out TUF + in-toto

I’ve been speaking quite a lot with quite a lot of people about the benfits of in-toto and TUF together. Indeed, my reaction after saying “hey, you don’t need TUF to use in-toto”, is “but they do go really well together”.

Although this is an important milestone for the history of cryptographic hash algorithms (if that’s even a thing), the practical implications are more nuanced. As it is with the emerging trend of branded vulnerabilities — (this one is called shattered) — the details are lost in a sea of PR-littered vacuity and witty names for vulnerabilities.
