Try this: ^.*(?=.{8,20})(?=.*[a-z])(?=.*[A-Z])(?=.*[-_]).*$ or just look around in the forum

You can use this regex:

^(?=.*?[A-Z])(?=.*?[a-z])(?!.*?[=?<>()'"\/\&]).{8,20}$

But it will be better in future if you show your own attempts to solve the problem.

hey special character is not compulsary ok. – Swapnil Jan 10 '14 at 14:21
It may include special chara that means the special chara is not compulsary. – Swapnil Jan 10 '14 at 14:22
It is definitely not made necessary by above regex since I have `(?!.*?[=?<>()'"/\&])` which means those listed characters are NOT allowed. – anubhava Jan 10 '14 at 14:25

Have you tried this? - ^(?=.\d)(?=.[a-zA-Z]).{4,8}$

I also found this within this site: ^(?=.[a-z])(?=.[A-Z])(?=.\d)(?=.[$|~=[]'+@.-])[a-zA-Z0-9$|~=[]'+@.-]{8,}$
