Password Strength
 

Hi friends,
The code i attached is used for checking password strength!. I have a html page which calls this.
Problem is if i change the following code
Code:

if (bCheckLowerCase)

    {

        strCheck = "abcdefghijklmnopqrstuvwxyz";

        if (doesContain(strPassword, strCheck) > 0) 

        { 

                nCombinations += strCheck.length; 

            }

    }



to 

 Code:

if (bCheckLowerCase)

    {

        strCheck = "a";

        if (doesContain(strPassword, strCheck) > 0) 

        { 

                nCombinations += strCheck.length; 

            }

    }



then also if i enter "abcde" the thing works..ie it then  also works for all lowercase alphabets.. how does it do so..



also what  does this part of code do..

 Code:

// -- 500 tries per second => minutes 

        var nDays = ((Math.pow(nCombinations, strPassword.length) / 500) / 2) / 86400;

 

    // Number of days out of password lifetime setting

    var nPerc = nDays / nPasswordLifetime;

    

    return nPerc;

Am worse in java so confused!
Please help!

JavaScript is client-side. You are allowing the user's own computer to check his password.
