Storing && Retrieval Of Encrypted Username And Password Hashes
Nov 22, 2006
Can somebody pls guide me on how i can Store & Retrieve Encrypted Username and Password Hashes.
I want to know following :-
1. I'm doing all the encryption and calculating password hashes on client side (VB), which i want to store in SQL Database when a new user account is created. I want to know what data types to use in Database. I will prefer not to use strings at all on client side due to secruity issues, i want to do all transfer in bytes -> to and from SQL server. How i can do that
2. How the connections can be made encrypted or more secure when doing these communcations.
3. I want to know if this is the right approach or to use the built in features of SQL Server 2005, main reason for not using that is that not all Encryption and Cryptography are supported...
pls help me on this as i'm fairly new to this.

I put this together to export the user name /password to a csv file to test my SP to output the user name/password.
DECLARE @user_name varchar(50)
DECLARE @psswrd varchar(10)
SELECT @user_name ,@psswrd
FROM ngweb_bulk_enrollments
EXEC master.dbo.xp_cmdshell 'bcp NGDevl.dbo.ngweb_bulk_enrollments out C: est.csv -Sserver1 -T -t, -r
-c'
This works but I don't get the headers in the file. How can I include the headers?

I built an eommerce site on my local computer at work. It's now time to
put the site on our server and get things rolling... anyways, I'm
trying to perform an sqldump so I can gather the appropriate text files
so I can upload the database. Anyways, the sqldump program I am
using requires a username and password to access the sql database.
I am using MSDE and have no clue as to what the username and password may be....
My VisualStudio .Net automatically connects when I work on the site.
Does anyone know what the default username and password may be or what my options are to get this sqldump to work?
Any help would be appreciated.

I have a USERS table on an SQL Server 2000 with two fields, USER_NAME AND PASSWORD, and I want to encrypt the passwords when I stored them on the table.
I used {Encrypt N ‘MyPassWord’} to encrypt the password and it looks that the passwords have been encrypted.
Went, however, I execute a SELECT statement for a specific password all passwords are returned.
This is a small sable code:
------------------------------------------------------------------------------------------------
CREATE TABLE dbo.Users
(
User_Name nvarchar (10) NOT NULL ,
PassWord nvarchar (50) NOT NULL
)
GO
INSERT INTO USERS (User_Name, PassWord)
VALUES ('MyName', {Encrypt N 'MyPassWord'})
GO
INSERT INTO USERS (User_Name, PassWord)
VALUES ('YourName', {Encrypt N 'YourPassWord'})
GO
SELECT * FROM USERS
WHERE PassWord = {Encrypt N 'MyPassWord'}
(2 row(s) affected)
-------------------------------------------------------------------------------------------------
Unfortunately both (All) rows are return
Is it any way to encrypt password and be able to select them?
Is it any other way to encrypt data into the database?
Thank You
Elias

Does this make sense for a logon table:CREATE TABLE Logon(ID INT NOT NULL IDENTITY PRIMARY KEY,name VARCHAR(15) NOT NULL,password VARCHAR(15) NOT NULL)GOCREATE UNIQUE INDEX IX_Logon_Name ON Logon(name)CREATE INDEX IX_Logon_NameAndPassword ON Logon(name,password)GOI do want the name to be unique but also will search frequently on bothname & password. Is this how it should be done? I don't fullyunderstand the difference between placing a single index in name &password VS one on both name & password.

I have two questions -
1. I have deployed the reports on our webserver. When I access the link http://servername/Reports from IE it asks me for a username and password the first time. I tried all the passwords including admin user/pwd but the dialog remains there. I close IE and start again I can access the reports. For your information, the checkbox 'Save my password' is checked in the reports. Does anyone know why the username/password dialog appears the first time?
2. Sometimes some of us get a 'Page cannot be displayed' while the others can access it. I have to start Reporting services and everyone can access the reports. Any ideas?
Thanks!!

How do I specify the SMTP username and password for reporting services? It seems like I can specify one for SQLmail, but not reporting services? How the heck is anyone going to use the email feature of reporting services without being able to specify smtp credentials or making their mail server an open relay for spam??

Hi everyone,
I am currently reading ASP.NET unleashed and practising few examples. The following code converts a user's text into a symmetric encryption:
'nd: define keys
Const DESKey As String = "ABCDEFGH"
Const DESIV As String = "HGFEDCBA"
'nd: convert string to byte array
Function convert2ByteArray(ByVal strInput As String) As Byte()
Dim intCounter As Integer
Dim arrChar As Char()
arrChar = strInput.ToCharArray
Dim arrByte(arrChar.Length - 1) As Byte
For intCounter = 0 To arrByte.Length - 1
arrByte(intCounter) = Convert.ToByte(arrChar(intCounter))
Next
Return arrByte
End Function
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
Dim arrDESKey As Byte()
Dim arrDESIV As Byte()
Dim arrInput As Byte()
Dim objFileStream As FileStream
Dim objDES As DESCryptoServiceProvider
Dim objEncryptor As ICryptoTransform
Dim objCryptoStream As CryptoStream
'convert string to bytes
arrDESKey = convert2ByteArray(DESKey)
arrDESIV = convert2ByteArray(DESIV)
arrInput = convert2ByteArray(txtInput.Text)
objDES = New DESCryptoServiceProvider
'pass keys
objEncryptor = objDES.CreateEncryptor(arrDESKey, arrDESIV)
'create to file to save password
objFileStream = New FileStream(MapPath("secret.txt"), FileMode.Create, FileAccess.Write)
'pass in file and keys
objCryptoStream = New CryptoStream(objFileStream, objEncryptor, CryptoStreamMode.Write)
'pass in text
objCryptoStream.Write(arrInput, 0, arrInput.Length)
objCryptoStream.Close()
lblDone.Text = "Done!"
End Sub
It works fine. But, how to i save this encrypted password into a database field instead of a writing it to a file? Also, could some please tell me how to paste code into this forum? I tried <code></code> tags but it did not work.
Many thanks,
Kevin

I have multiple databases, one for each client. I created a master report. Then I created links to this report for each client database in separate client-specific folders. I parameterized the connection string so that the server name and the database name are parameters of the linked report. The connection string is: ="data source=" & Parameters!SrvrName.Value & ";initial catalog=" & Parameters!DbName.Value.
The problem is that the security for now is Windows Authentication. (We are in the testing phase). However, my users will be both internal (company) and external (client) users. We do not want to set up database user IDs for each client user. I could create a single SQL account that has read access to all databases, relying on the Reporting Services security. But I would prefer to create separate SQL accounts for each database as the information is sensitive. Then I would probably pass that information in as a parameter to the report as well. Either way, I would have to include the password somehow. But, if I do that, I'm not sure how to include the password parameter. I would like it to be secure and passing it in as a parameter is not very secure.
I would really appreciate some suggestions on how to proceed.

Hello. I have recently installed MS SQL SERVER 2005 and when I was installing it, it asked me for the username and password, and there I had 2 options: either write my own, either select "Use Windows Authentification". I selected the "Windows Authenthification" ( I guess that means that it uses my username and password from Windows ).
Now, Im trying to connect to the Server using Java and JDBC, but I have a problem: I have to specify the username and the password of the connection! My windows' only account is "Vlad" and I have no password. I tried these options, but it didn't work. I also tried with empty string "", and with "sa", "sa" but it didn't work either. I get an error saying that "Login failed for user 'Vlad'. The user is not associated with a trusted SQL Server Connection."
Any ideea of what the username/passwords are or how to get them?.
Thank you for your time.

I am trying to use a first_name , Last_name and append this as username something like mike test and create username like 'Mtest@123'. and password as well.
The first_name, last_name comes from a table called "person".
Right now the user name and password is hard coded and I need to make this dynamically generated, is that possible within SQL?
How can I do this within SP? Below is my sp:
Alter PROCEDURE PatientEnroll (@person_id AS uniqueidentifier)
AS
BEGIN
SET NOCOUNT ON
INSERT INTO dbo.ngweb_bulk_enrollments(row_id, person_id,practice_id,

Are you one of those, like me, who has plenty of SQL Servers in Enterprise Manager, but have forgot over the time which username and password you used to add the SQL Server to the list of servers and groups?
Run this VbScript code!Dim oApp, lServer, lGroups
Set oApp = CreateObject("SQLDMO.Application")
For lGroups = 1 to oApp.ServerGroups.Count
For lServer = 1 To oApp.ServerGroups(lGroups).RegisteredServers.Count
MsgBox oApp.ServerGroups(lGroups).Name & " - " & _
oApp.ServerGroups(lGroups).RegisteredServers(lServer).Name & " - " & _
oApp.ServerGroups(lGroups).RegisteredServers(lServer).Login & " - " & _
oApp.ServerGroups(lGroups).RegisteredServers(lServer).Password & " - " & _
oApp.ServerGroups(lGroups).RegisteredServers(lServer).UseTrustedConnection
Next
Next
Set oApp = NothingEDIT: Typos

Hi All
I am trying to connect to my report server through URL access and then trying to retrieve some values from my SSRS from my local machine like :
<a href="http://IPAddressOfServer/ReportServer/Reports/?%2fDashboardReports%2fHorse_Profile&rs:Command=Render&HorseID=117415"><%=name%> </a>
But when i click on this hyperlink it asks for the username and password for that server.
However , i am using the following code to connect to my server :
String url = "http://IpAddressOfServer/ReportServer/ReportService2005.asmx";
ReportingService2005Soap port = null;
ReportingService2005Locator loc = new ReportingService2005Locator();
// Retrieve a port from the service locator
try {
port = loc.getReportingService2005Soap(new java.net.URL(url));
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
org.apache.axis.client.Stub stub = (org.apache.axis.client.Stub) port;
stub.setUsername("IpAddressOfServer\USERNAME");
stub.setPassword("PASSWORD");
It is getting connected withut any problem and i am retrieving values also from my SSRS.
But the problem comes when i want to click on some hyperlink and it should go to the report server and generate the corressponding report.
But it is asking for the username and password which is not required.
If there will be some security issue it must not be get connected with the server through the code i am using.
I have tried to connect with wrong password but it gives unauthorized exception.
SO please anybody has any idea, advise me.
Regards.

Am getting ready to perform upgrade/migrate from 2000 to 2005 and have concerns about all the usernames/passwords converting accurately, as the existing 2000 instance has hundreds of them (am used to conversions with few usernames/passwords). Any suggestions as to the best way to proceed. The upgrade/migration is being done on the same box. Will a straight upgrade convert the master db cleanly with u/p, what issues does a migration on the same box present? Thanks.

Hello -
I dont know something weired happened on our MSSQL server today. We are able to connect to any Databases from Enterprise Manager from a Remote server.
Once we logged in and connected to a database on my database server, it keep prompting for the user id and password as we browsing through different tables in that database?
(Right click on the table then select Open Table -> Return all rows -> and it prompts for password )
Now when we enter password the contents of Table are displayed and now when we try to see contents of another table in the database it again prompts for password.
Any Idea whats wrong? How this can be resolved as it was not happening before .. :(
