    8181[comment:44:ticket:217 #217:c44] says that, if we don't need to prevent collisions, then we can use a K-bit hash for K-bit second-pre-image resistance. However, see [comment:6:ticket:882 #882:c6] for a counterargument saying that 50 extra bits or so are needed to be secure against multi-target attacks (i.e. T = 50). This page has now been updated assuming the counterargument is correct.
