The performance may not be so good with sufficiently large RSA keys, but I think that is a bottleneck only when creating those keys and signing metadata with those keys. Verifying signatures created by those keys should be cheap enough, and that is how most people would use TUF (for reading, not writing). Vlad, what do you think?

Ok good, as long as what someone installing a package needs done can be done in pure python that's fine. Pip can't have dependencies in the traditional sense so everything needs to be embeddable and pure python. An optional C module for speed ups is fine.

What about a precompiled Python extension?  Bundling wheels?

Packaging tools on the other hand IMO can require compiled code.

Among other things, the PyPI server will also have to change a bit to generate some TUF metadata itself.

Right now i'm porting over database tables to be "owned" by Warehouse (Warehouse and legacy PyPI run in tandem). After that i'll be working on porting the existing API. I'm hoping to have something that people can install from to test in a month or two.
