Yes. If the source files are being modified via a MITM attack (which is
trivial if the host uses HTTP) the checksum is still useful.

I would suggest considering TUF - The Update Framework or stealing their
signing scheme which withstands all kinds of attack scenarios.

Before you discuss it further, Ralf and piequiex, I did announce using
bofh excuses earlier in this thread.
I actually pulled the part with Germany randoly from collection of bofh excuses.
None of any of that was real.

We're having extreme gravity fluctuations, please move your pc to the
floor rapidly.

cheers!

This happen automatically on mail service side. I see nothing offensive in
this action.

You mean the source files that you downloaded and then hashed...

It would at least indicate that the source file has been tampered with in
some way. Even though there would be no way to know the "correct" checksum.

But using and hash value without the possibility to verify the hashed
files, adds no security. It provides a false sense of security instead.

I agree that we should use a strong hash by default where it makes
sense. But in the absense ob effective validation of upstream packages,
this is meaningless.

Then

  1) you could argue our using SHA512 is meaningless, but
  2) it doesn't matter; we should still be doing the Right™ thing.

Welp, sounds like you a kernel bug, either the kernel just locked up or

I need to correct Martin, only your mails are censored:

https://lists.archlinux.org/pipermail/arch-general/2016-December/042686.html

They censor your mails and after that they fix the broken PGP signature,
too.

I never noticed that content of my mails is missing in the archive,
resp. for mails that came through the list and it would be easier to
do this, since I don't sign mails sent to mailing lists.

Ralf
