If a password is alphabetic only (all letters) and not case-sensitive, how many possible combinations are there if it has seven characters?
1,853,494,656
8,031,810,176
7,793,657,239
59,406,880
There are 26^7 = 8,031,810,176 possible combinations. -To clarify, there are 26 letters in the alphabet. So... 26 x 26 x 26 x 26 x 26 x 26 x 26 = 8,031,810,176 --HDL.
Was this a genuine question and if so...are calculators allowed?! -- The teacher I spoke to said that you could have scratch paper. But he also said there wouldn't be any math on the CEH (like this, or subnetting). I'm about 65% willing to trust that... so I'm prepared to do this long-hand if I need to. OK, so this discussion begs the question, if Skillset "test engine" does not contain actual or even likely CEH questions...what is its purpose?
