-*p* is the success probability of an attack (0 < *p* <= 1), and *c*(*p*) = sqrt(2.ln(1/(1-*p*))). (For example, *c*(1/2) = 1.18 and *c*(2^-40) = . For small *p*, ln(1/(1-*p*)) approx= *p*.)

-*N* is the number of targets for preimage attacks; this assumes that the attacker has stored the relevant hashes for *N* files and is content with finding a preimage for any of them.
