I'm evaluating different hash algorithms for use in my application. One of the kind of algorithms I am looking at are cryptographically secure ones to protect against DOS attacks.
SipHash seems pretty great, but the creators seem very careful to not call it "cryptographically secure".
In the SipHash paper (PDF), they call it “cryptographically strong”, but not secure. Is there any reason to trust SipHash over SpookyHash if both have no known DOS attacks and neither is “cryptographically secure”?
