Which would be harder to crack: a password comprising of n characters randomly selected or a password comprising of x randomly selected characters repeated m times so that m*x=n.
As oppose to:
As far as I can tell none of the above contain dictionary words and they all contain a good mix of keyboard characters, i.e the attacker would to try capitals, numbers, special chars etc. so they should be hard to crack.
Why might the former example be harder to crack than either of the latter two?
The intention is be able to provide password advice that renders brute forcing attacking really difficult but gives a human easy visual / muscle memory.
For the purpose of the question assume the attacker is coming in blind, they have no knowledge of the pattern or whether or not a pattern would be used and there is no requirement that a password be a repeating pattern, it could be anything, though they do know that any character and any length is allowed for the password.
