[Bf-committers] Bundling Python `requests` module for 2.70

I did a local pip install of the requests file to take a look at the
cacert.pem file. It would appear that it is a copy of all the main
certificate authorities for use with SSL, so it would be rather large.
I was a little concerned to see other posts online (
mentioned things like being slightly out of date, ignoring checks for
revoked certs, and what not, so they seem a little on the slow on the
update end of things.
I can't (won't) verify the actual authenticity of all of those certs to
prove that they aren't "fake" or anything, but probably minor since only
HTTPS requests using this lib would be able to be MITM'd if there were some
fakes in there (unless they found a way to install into your browser
storage via another script since users generally have full access to their
own browser settings, for example).
Personally I wish they would set this up to point at the system maintained
certs, but these paths vary too much on the OS's and would require root
access. If you ask me, it is a can of worms to install CA files on to a
users system as that is half of the attack (getting the file on someones
computer, the second being to install it in the proper place and MITM a
users connection). Wouldn't it be better to leave out and tell the user
that if they want SSL, they should configure the library to point at the
system wide certs instead?
