Determine the appropriate criteria for a cryptographic hash function h. We can find different data x and y where h(x)=h(y). For a given digest z, it is impossible to reconstruct the data x where h(x) = z. For a given data x where h(x) = z, we can find a data y different from x where h(x)=h(y)= z. For a given data x and a key k, it should be easy to compute h(x) = z using the key k.
