22 | | ''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''.) |

24 | | ''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. |
