i need to verify if the password is correct for a user.
i have this code: private bool checkOldPasswordValid(string password, string username)
{
using (DirectoryEntry entry = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer"))[code].....
but this just gets the name and doesnt verify the password.
I need a control that will accept an email address and password/verify with a password strength indicator.
Has anyone seen a similar type control?
For our website, we have decided we would like to maintain our user passwords as encrypted binary data in our database. We are using ASP.NET 3.5 to host our site and SQL Server Express 2008 for the database, both running on the same server. When a user logs in and submits a username and password, there will need to be some sort of encryption or decryption in order to verify the credentials. To me, it would appear that there are 3 ways to do this:
1)[C# Encyrption] On User creation, perform encryption in the Web App and submit the encrypted password to the database. To verify credentials at Login, perform the same encryption on the submitted password and ensure that it matches the value stored in the database.
2)[SQL Encryption] On User creation, submit the plain-text password to the database and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, have the database perform decryption on the password during the SELECT statement, and compare the plain-text submitted password to the one in the database.
3)[Mix] On User creation, submit the plain-text password to the database, and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, perform the same encryption algorithm used by SQL on the submitted password ( is this possible? ), and ensure that it matches the value stored in the database.
Does anybody have an opinion as to which of these options is best? Number 1) is the most familiar to me, and would be the easiest to use with LINQ to SQL ( which is our current data model ), so I am leaning towards that. But if there are better options I would love to know about them.

My Login.aspx form in Visual Studio 2013 just seems to be 'static' after I enter the correct username and password. I don't get any errors. My Login.aspx.vb code looks like this:

Imports Microsoft.AspNet.Identity.Owin
Imports System.Linq
Imports System.Web

Don't I need a file name/URL to direct the user to after he has successfully logged-on? How would I script that? Finally, I only have one Web.config file (associated with Register.aspx) and that looks like this:

<configuration>
<system.web>
<customErrors mode="Off"/>

I don't need another Web.config file for Login.aspx, do I?

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?
View 4 RepliesI am using Entity Framework with partial classes added on so I can use DataAnnotation attributes. Does anyone know how to add a data annotatin which will verify that a field is a whole number (or a DataType of int or long)? I'm surprised there is no [DataType(DataType.Integer)] attribute. I tried to create a custom attribute, but it doesn't work because the value it receives is always null:

so I have code like above, I need to assure a record was actually returned before trying to use it... I assumed I could test for null, but that doesn't appear to work.
I tried: if (task != null) {yada yada yada}
but if I put an ID that doesn't exist in my querystring it throws an exception 'sequence contains no elements'. I realize I can catch the exception but I want to understand how I should be checking for a returned record. The .Single method intellisense says it returns exactly one record or throws an exception if more than one is found... is it also throwing the exception when zero are found I'm not sure if the issue is my check for null or that line that calls .single itself? Now I'm guessing I'm supposed to just catch the exception on the line that's calling .Single... yes?

I posted this previously but it ended up in Languages/C# rather than here. I'm not sure if I chose the wrong forum or the admin moved it. I wanted it in here so I'm re-posting it:
I have an APK file (android application archive, same as JAR file format) that I need to determine whether or not is signed, and if so, extract the certificate info.
The JDK provides a command line tool to do this:

I'm trying to determine if there's a way using the Security classes to accomplish the same thing in C# code.
Does anyone check the domain of an email address as part of their verification steps? eg. Confirm that gmail.com exists if the user specified blah@gmail.com as their address.
I should note that in my webapp an existing user can forward invites to their friends. I have no need to verify those invites at all. Rather, I just want to warn my user if a typo etc. may be sending an invite to the wrong person. Is this even worthwhile to do?
How do I check if a value in the dropdownlist is in the table bound to the girdview?
Some fields bound to the gridview contain values that are not in the dropdownlist. I would like to check in the code behind whether the value is there and if not set the ddl selected value to "Select" with a value of "". If the value is there then set the selectedvalue to the value in the gridvidew.
Also, the ddl is nested inside an edit template.
Here's an example:
