What are you trying to do? Detect corruption? ZIP has internal CRC-32 checksums that should protect against accidental corruption.
Protect against malicious attack? Running GeoServer over SSL/TLS will protect against malicious modification and protect against server identity spoofing. Detect data change? Hashes will not be useful for detecting data change because timestamps in many payload formats will cause them to be different every time. Kind regards, Ben.
