Regular Expression for a password

[Joe]

Hello,

I want to verify that a password is:
- Minimum 7 characters (can be any character)
- Includes at least 1 number.

I thought this would work but it does seem to:
^(?=.*[a-z])(?=.*[A-Z]).{7,}$

Thanks,
Joe

There is no check for a number in there at all....

^(?=.*[0-9]).{7,}$

should do the trick.

password complexity in your applications:
^.*(?=.{7,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=]).*$

The regular expression enforces the following rules:

a.. Must be at least 7 characters
b.. Must contain at least one one lower case letter, one upper case
letter, one digit and one special character
c.. Valid special characters (which are configurable) are - @#$%^&+=
