I agree with Martin. If the point is to "to protect against cryptography
that is not used", then not using the de-facto standard in signing
open source distribution files, which today is PGP/GPG, misses that
point :-)

Note that signing such distribution files can be handled outside
of the wheel format PEP. It just way to complex and out of scope
for the wheel format itself. Also note that PGP/GPG and the other
signing tools work well on any distribution file. There's really no
need to build these into the format itself.

It's a good idea to check integrity, but that can be done using
