Keep That Password Encrypted In Code While Checking It Against A Data Store?

Jan 18, 2011

Even with https enabled, you can write a password to the event log in code-behind. Any way to keep that password encrypted in code while you're checking it against a data store?

(using Login control)

(couldn't add comment to Andrew's answer, so I'm putting it here)
NTLM uses the username/password of the machine the user is logged into right? For this, I was thinking using ActiveDirectory on the server as the data store. It would have a diferrent un/pw than what the user is currently signed in to their machine as.

Web Forms :: Forms Authentication With (Encryption) Encrypted Password?

May 7, 2015

I was able to encrypt the password and save it in the database but I need to encrypt the password now when the users try to login.  For example, user comes and types his/her username and password but the password is already encrypted in the database, how can I decrypt and authenticate the user? 

protected void ValidateUser(object sender, EventArgs e)
{
int userId = 0;
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand("Validate_User"))

[code].....

here is the decrypt function

private string Decrypt(string cipherText)
{
string EncryptionKey = "MAKV2SPBNI99212";
byte[] cipherBytes = Convert.FromBase64String(cipherText);
using (Aes encryptor = Aes.Create())

[Code]......

DataSource Controls :: Save Encrypted Password Into Database Table?

Jun 14, 2010

I'm using ASP.NET 3.5 and Visual Studio 2008 C#.

I'm creating a website and currently making tests for registration. I've manage to create a registration form in the web site and save what the user inputs in the textboxes into a sql server 2008 database.

One of the fields is Password. What I want know is how do you save the password into the database but the database stores it encrypted. That way I'm just able to see the password encrypted. Then when I make a log-in form how to validate the password input by the user with the encrypted one and give a succesful login.

Security :: Encrypted Password - Sort Of Encryption Or Decryption In Order To Verify The Credentials

Jun 16, 2010

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.

Security :: Using ASP Tools For Login And Create User / Login Tool Is Going To Get Userid And Password Info?

May 25, 2010

I've created a page to add users, using the CreateUserWizard, I use the Login Control to login.

I have setup the config file to use my SQL server, not express

<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=xxxx.xxxx.xxxx.xxxx;Initial Catalog=aspnetdb;Persist Security Info=True;User ID=xxxx;Password=xxxxxx" providerName="System.Data.SqlClient" />

I go to the create user page, add a user.

I can SEE the user on the database using Server Management Studio...

I go to signon and get "Your login attempt was not successful. Please try again."

I have not customized the login control in any way. (OR the createuserwizard)

HOW can I tell where the Login tool is going to get userid and password info?

How can I tell if it is not finding the user or the password does not match?

How To Implement Dynamic Changing Password

Mar 22, 2010

What is the Best practice of dynamic changing password for this scenario?

The scenario is:

There are three web apps using ASP.NET.

App1 checks the passwords of app2/app3 to authenticate the identity, and if app2/app3 is authenticated then app1 is allowed to receive information from App2 and App3.

And app1 has to change the passwords of app2/app3 every two hour for security reason.

Is it possible that there is a way to implement this scenario without app1 saving the passwords of app2/app3 for security reason?

Or is there any best practice for dynamic changing password scenario?
