Hi I am not so good in regular expression so I am here for your help.

I have field password which should be minimum 8 character length with atleast one numeric one special character one uppercase one lower case.

This is my regular expression which I have placed in regularexpressionvalidator
^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=]).*$

But this will accept only in this format Password@1. But I need to accept in any format with above condition. Please help me to solve this issue
