My guess is that if you could write a hash working the way you say, it
would be vulnerable to all sorts of cryptographic attacks: give up!
I have indeed given up and found other ways to incorporate the hash
while verifying the stream integrity.

By design, a cryptographic hash function (on average) changes half the
output bits when a single bit in the input is inverted.

Isn't that a little like the guy who committed suicide, cut himself up in

Some checksums are computed such that the checksum is part of the message,
and if all if well, the checksum of the entire message including the
appended sum is 0 or 0x
