Re: [opensuse-buildservice] adding checksums to the buildinfo

While this is basically true MD5 is used in OBS all over the place and
thus for consistency and code reuse reasons it might still make sense
to go with that. It should also be noted that the intent of the MD5
sum in Marcus' proposal is not to add a layer of security for
malicious attacks (that you better prevent by verifying RPM signatures
and SSL certificates for the connection (when using https)) but to use
it as a simple checksum mechanism to detect technical transmission
issues.

Anyway... isn't the bulk of the complexity of checking signatures the
computation of the hash value? (reading the whole package and
computing the hash implies processing massive amounts of data).

I don't see why verifying the package's signature would be so much worse.
