I met a problem, and I don't have experience to solve it. Thus, please give
me a help.
My question is:
I have a hash function: h().
I have a plain text: A
So I can get a hash value B = h(A)
Suppose that I have a reverse hash function: h'()
Then I can get a fade plain text A'= h'(B), probably A' is not equal to A,
but it doesn't matter!
I want to ask: Is it possible to build a reverse hash function h'() so that
h(h'(B)) is equal to B?
I do appreciate if you could answer me or send me a hint.
