Password generator

[ozzroo]

I have a registration page that creates a new user account. I was wondering I would I create a random alpanumeric password (in the password field) for each new registration in an sql server database. would it be best to use a stored procedure or do it through .net code.

if the first option is best, how do i incorporate/run the store procedure from my registration page and ensures it inserts into the new registration

thanks

You could use the Membership.GeneratePassword method.

Hi ozzroo,

The Membership.GeneratePassword method seems to generate rather complicated passwords although I believe you can tweak this (ca8msm ?)

I use this function that turns a Guid into an alphanumeric password

Public Function GetRandomPasswordUsingGUID(ByVal length As Integer) As String

        'Get the GUID
        Dim guidResult As String = System.Guid.NewGuid().ToString()

        'Remove the hyphens
        guidResult = guidResult.Replace("-", String.Empty)

        'Return the first length bytes
        Return guidResult.Substring(0, length)

    End Function

just pass along the number of characters you want such as

Dim _Password As String = GetRandomPasswordUsingGUID(8)
Membership.CreateUser(txtUsername.Text, _Password, txtEmail.Text)

HTH,

Jon

The Membership.GeneratePassword method seems to generate rather complicated passwords although I believe you can tweak this (ca8msm ?)

The method takes two parameters; length and numberOfNonAlphanumericCharacters

The numberOfNonAlphanumericCharacters is actually the minimum number of punctuation characters included in the returned string (as opposed to the maximum which would then allow you not to include any), so you can't actually make the password less "complicated", although you could strip out these characters afterwards if you really wanted. Personally, I prefer to leave them in to make the password more secure.

Thanks for your help guys.

I am creating the password perfectly with the punctuation characters. They are fine for now.

I may try the other function and see how it works
