Comment Comment by 7steps2much You are correct, at least in theory.Assume you have two inputs, A and B.A may hash to: A38uT75kjGz B may hash to: A38uHso629tSo yes, if you were to cut these off after the A38u then you would no longer be able to say for sure if you hashed A or B to arrive at your hash.Of course in practice this usually isn't a problem as long as you have "a long enough" output. parent 7steps2much 4 years ago
Assume you have two inputs, A and B.
A may hash to: A38uT75kjGz B may hash to: A38uHso629t
So yes, if you were to cut these off after the A38u then you would no longer be able to say for sure if you hashed A or B to arrive at your hash.
Of course in practice this usually isn't a problem as long as you have "a long enough" output.
