Each SlackBuild archive is signed by the SBo devs, so any modifications
on the server (or in-between) would fail subsequent verification. In
that case it's the GPG signature that you trust to verify the .info file
contents (and all the rest of the SlackBuild stuff), not the MD5 sum or
whatever else is inside it.
