Passwords with fghijkl are reported as more secure than they are

[davidjwilkins]

Describe the bug
The getLength function is supposed to strip sequential characters after a run length of 2. e.g. fghijkl should become fg.

However, because it first replaces the sequence asdfghjkl, it changes fghijkl to fgijk, which then becomes 'fgij, a length of 4.

To Reproduce

#14

Expected behavior
It should change fghijkl to fg
