In theory, as Richard already said, it's possible. In reality, the software
would have to be dumb to make it feasible.

seems like 16^32, assuming hexadecimal, as opposed to number of letter which
would make it 36^32. Maybe the random number generator is faulty or maybe
one of the above possibilities would explain this...
It comes down to the question: would you trust a client on the phone or
128bit encryption? People tend to say half truths, even in the case of
technical support that is related to hardware and desktop software. Find out
