I guess you could download it from the Jenkins job

although the job itself downloads over http from files.pharo.org… but
Jenkins should be fine enough if you are worried about MitM between you and

For SHA you still need a secure connection assuming the website wouldn't
get compromised,
or digitally signed releases assuming the signing won't be misconfigured,
or the keys won't get compromised.

But I agree that this should be solved, or at least improved; but then
again whole smalltalkhub doesn't use https and you are sending your
credentials in plaintext over the network (have fun committing from a hotel
room wifi)… security through obscurity can be incredibly efficient.

Of course that means that we need someone with the time and knowledge that
can invest effort into this.
