These are key samples. I think that the key generated by 8 digit hexadecimal(0-9, A-F),, it has 16^8 possibilities. I want to reduce the combinations by restricting conditions. e.g.
a) no more than three consecutive alphabet/numbers, AAAxxxxx , 111xxxxx (x)
b) no more than four repeating alphabet/numbers A1234AAA (x
four A's)
c) must include 1 alphabet
d) must use at least four distinct alp/numbers
how to do calculate the possible combinations?
