Even improperly used, digital signatures should never be worse than
simple checksums.  Having said that, anyone that is trusting checksums
as a form of authenticity validation is begging for trouble.  Checksums
are not, in of themselves, a security mechanism.  I can't stress this
enough.  There really isn't any comparison here.  Please stop comparing
apples and oranges.  No matter how hard you try, you can not make orange
juice from apples.
