I think that PyPI *should*, by the default, be the central authority to be trusted specifically for this item, that is the association between developers, projects and their GPG signatures. This is important because most people would be perfectly fine with trusting PyPI and can not be reasonably asked to acquire valid GPG key fingerprints through external channels for all packages they want to install. We cannot sacrifice this UX part as it is crucial for the pip/PyPI experience. On the other hand, it is perfectly fine to make sure you can configure pip to disable all trusts on PyPI (= not asking PyPI what is the official GPG fingerprints associated with a project). This is an advanced security feature that you might want to employ on your servers, but it cannot be the default. > All that I want pypi to do is to have non borked database where I can > register my software.

Most people want to be able to write "pip install django" and get django, with all the dependencies. That's it. They are doing it today through HTTP with not even a signature verification on the download, and they will be perfectly fine with trusting PyPI just like they trust Canonical when they write apt-get install (actually, technically we require *less* trust than those using apt-get, since the packages are not signed by PyPI but by the original developer). >> If you don't trust PyPI then you have to create and maintain your >> own mapping of key fingerprints to projects. > > Yes, that is what I want to do. That's OK, we can make sure in the design that you will be able to do it. -- Giovanni Bajo :: ra...@develer.com Develer S.r.l. :: http://www.develer.com My Blog: http://giovanni.bajo.it
