Thanks for putting this together! Just a few notes regarding key management: - the PSF board generally stays out of the technical details of running the python.org infrastructure, so it's likely that any root keys would be handled by the PSF infrastructure committee. A (2, 4) or (3, 5) trust configuration would likely be manageable at this level. - at the target delegation level, PyPI supports the registration of new projects through the web service (see http://docs.python.org/2/distutils/packageindex.html). If my understanding of target delegation is correct, this means the "simple" and "packages/source/<letter>" delegations will need to be (1, 1) and online. - higher levels of the target delegation hierarchy could conceivably be kept offline, but there seems little value in doing so if they're trusting on online (1, 1) key - many PyPI packages are maintained by single developers, so (1, 1) or (1, n) is likely to be the only generally feasible level of signing at the project level. With the current focus being on getting an improvement from the status quo that we can successfully deploy in a reasonable period of time, the target delegation side of things probably needs to be substantially simpler in the initial iteration. Yes, it leaves us open to certain vulnerabilities we would like to remove in the long run, but we need to be very cautious in the additional demands we place on the users uploading to PyPI. It may even mean the initial iteration allows projects to rely on a PyPI provided signing key for their TUF metadata, using the existing upload mechanisms to add the files to PyPI.
