regular expression validation

[jim_balthrop]

i have a form password to be server validated
the password needs to be at least 8 characters with at least 1 being numeric.

this expression example that i found is supposed to be 6-8 characters with at least 1 letter

/^(?![0-9]{6,8})[0-9a-zA-Z]{6,8}$/

can anyone help change this expression to match my requirements?

i can see the {6,8} being {8,9} but not sure of the other changes?

thanks for your help

Try:
^(?=.*[A-Za-z])(?=.*[\d])(?!.*[A-Za-z0-9])(?!.*s).{8,}$

That should require at least 8 characters with one digit.
It might be easier just to do separate tests, though. Up to you, really.

Pseudocode:
If Len(password) >= 8
RegExp = "[\D]"
stripped password = RegExp.Replace(password,"")
If Len(stripped password) > 0
OK!
Else
You forgot to include a number!
End
Else
That's not long enough
End

couldn't get that to work but i did find the answer on line

i found this expression for at least 1 numeral and at least 1 letter
/^\w*(?=\w*\d)(?=\w*[a-z])\w*$/

i ended up applying a seperate validation for the minimum characters of 8 and applied both the entry length and the regular expression validation to the password textbox

thanks for your help; it pointed me in the right direction
