[arch-devops] Arch Linux ISO Checksums on archlinux.org

Linux Mint had a security breach [1] and was serving an infected ISO. I
think this would be a good moment for thinking about our Arch Linux
Download-page on [2]. I recommend to change the checksums. MD5 and SHA1 are
both broken.[3][4]

What do you think about using SHA256 ( or even better SHA512 ) for this?
Maybe we should also sign the ISO with a GPG-Key.

I don't mean that we should remove the MD5 checksum but we should add some
other checksum and sign the ISO. 

You can call me paranoid but I don't want too see such a security fail on

Best regards,
