Does The Password Have Alphanumeric Character
Apr 12, 2010
My ChangePassword method returns a boolean value indicating whether the change of password has been successful or not. When the user enters a new password, I want to check if the password length is at least 8 and there is at least one non-alphanumeric character(both these parameters specified in the web.config file). If I want to check in my code if the password entered is at least 8 characters, I would write some code like this:
if(newpassword.Length !=8)
{
//do something
}
Like the Length property, is there some property that can check if the password contains at least one non-alphanumeric character?

I am using Forms Authentication in a new ASP.NET 3.5 Application.I have created the Tables in my database and run the Web Site Administration Too.When I try to create a user I get a password error no matter what I throw at it and I am becoming sure of that this is a symptom of an a setup error and not a password problem.One of the things that I notice is that my aspnet_Applications is empty and I am not sure what is supposed to fill it.I have tried to delete all the aspnet tables and done the procedure again but with the same result.

How can I use Membership.GeneratePassword to return a password that ONLY contains alpha or numeric characters? The default method will only guarantee a minimum and not a maximum number of non alphanumeric passwords.

I'm trying to connect to my sql server 2008 database and I'm using impersonation within my asp.net 3.5 application
<identity impersonate="true" userName="testUserName" password="test&test" />
Naturally the compiler won't compile until I use the escape character:
<identity impersonate="true" userName="testUserName" password="test&test" />
So it compiles, unfortunately when I run my app, it get this:
Parser Error Message: Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.
Source Error:
<identity impersonate="true" userName="testUserName" password="test&test" />

I looked up the msdn documentation and it says that InvalidUserName is thrown when it does not find the username in the database, which is fine because the user I am creating should not exist in the database. If I use test@example.com, it works, but if I try it with test.@example.com, the status from Membership.CreateUser is InvalidUserName.

How to read character by character in line from text file?

I have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this:
hashedsalt =
Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--")
hashedpassword =
Digest::SHA1.hexdigest("#{hashedsalt}:#{password}")
So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data.
But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related.
So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle.

I'm trying to implement a code that will generate a fix lenth alphanumeric code; number from 0...9 and capital letters A...Z. I want the code to be formated as this: XXX-XXX (where X representes a random character between 0...9 and A...Z). It doesn't matter if the letters and/or the numbers repete. But it will be great if the don't. I'm using VB.Net. How can I do this?

I specified to have a user creation wizard that accepts a password with NO alphanumeric characters:
<add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="watermeConnectionString" enablePasswordRetrieval="false" enablePasswordReset="true"
requiresQuestionAndAnswer="false" applicationName="/" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="5" passwordAttemptWindow="10" passwordStrengthRegularExpression="(?=.{6,})[a-z]+[^a-z]+|[^a-z]+[a-z]+"
minRequiredNonalphanumericCharacters="0"/>
still, I do get the error that I have to provide at least one alphanumeric character.I do so and the error is still the same.why? is my regex wrong? I also took out the "confirm password" step. is that ok?

When a user that has their IE set to save passwords hits my "Reset Password" form, the first text box set with TextMode set to "Password" is populated with the users saved password. Understandable, this is not the affect I would like as this is their "old" password. I cannot set the text of a text box with mode set to "Password" (naturally). Does someone know how to suppress or clear this value when IE is saving passwords?
