I'm using the following regex to validate password complexity:
/^.*(?=.{6,12})(?=.*[0-9]{2})(?=.*[A-Z]{2})(?=.*[a-z]{2}).*$/
In a nutshell: 2 lowercase, 2 uppercase, 2 numbers, min length is 6 and max length is 12.
It works perfectly, except for the maximum length, when I'm using a minimum length as well.
For example:
/^.*(?=.{6,})(?=.*[0-9]{2})(?=.*[A-Z]{2})(?=.*[a-z]{2}).*$/
This correctly requires a minimum length of 6!
And this:
/^.*(?=.{,12})(?=.*[0-9]{2})(?=.*[A-Z]{2})(?=.*[a-z]{2}).*$/
Correctly requires a maximum length of 12.
However, when I pair them together as in the first example, it just doesn't work!!
What gives? Thanks!
