: Don't have that book, but if your book says "P<math>\neq</math>NP implies one way functions", then it's certainly talking about complexity (worst-case) one way functions, not cryptographic (average-case) one-way functions. It can get confusing, but no one really does anything with worst-case OWFs these days. [[User:Blokhead|Blokhead]] 03:09, 30 October 2006 (UTC)
 
I am quite certain that having a constructive proof of P=NP would bring you no closer to reversing SHA-1 or SHA-256. --- Joshua
