SHA-2 and SHA-3 are used not only for networking, they are general. Hence, they were developed to be slow enough to prevent brute force for some other applications.
Since you are asserting that the hash functions must be "slow" in order to resist brute force attacks, could you perhaps give us an estimate of *how* slow they must be? And how you arrive at that (e.g. how much resources does the attacker deploy, and how long walltime do you give the attacker)? /Bellman
