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...
I need help(Tutorials or online links) regarding storing and retrieval of files in Sql server (BLOB) using ASP.net and C#. Secondly,Is it possible to search file in BLOB using SQL server Full text search service.
when we built the login control by built in login control of vs2005 the passwords are saved in the database which is automatically created.how can i get the unencrypted form of these passwords from database.
I wonder if it is possible to retrieve encrypted password somehow? Like I have saved password (blueRays) in encrypted formate. How can I retrieve it "where password='blueRays' "?
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?
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?
I Forgot for my longtime used home expense update application password which has backend sql expressedition database.
i was used the application before 3 years, unfortunately i stopped updating my home expendature to the software.and now i require to login the application but i dont how reset the password in db, i have open database include tables of users profile. and password, but its encrypted.
I built an vb.net app that set some parameters and runs a store proc. Besides, the vb.net app creates an user with admin rights, his credentials: username and password are stored in DB.
I thouth to encrypt password with hash + salt method.
The problem....
Hashing password means that they are not decrypted ...only compared ..and here the problem....I would like to reuse this password to be used in the addlinked server store proc and other sql statement.
How can I Manage encrypted password to be used later...
I have installed MSDE using the following parameter:
commandline> setup SAPWD="MySAPwd"

then i logged in using :
commandline> osql -E
It successfully logged in... and i was able to create databases and tables...
can someone tell me how to set a username and password for MSDE please... so that i can connect to MSDE using WebMatrix...
i m coming from a PHP/MySQL background so i know SQL and stuff... but dont know how to handle and configure MSSQL...
waiting for the response.. thanks in advance... Bye. Kamran.
I need to get into a database and need the password and username for a Microsoft SQL Server v.6.5 database. Can you help or do you know someone else who can? This database is owned by us and this is a "legal" project.
Thank you.

My problem iam unable to connec to the SQL Server from my .net windows application.My application code is
Dim strCon As String Dim sValue As String Dim strQuery As String Dim dsEventTransac As New DataSet Dim daEventTransac As New SqlClient.SqlDataAdapter Dim rowCount As New Integer Dim oWebService As New WebReference.TkmService 'Dim nwRow As DataRow 'Dim delCmd As SqlClient.SqlCommand

When i donot specify user ID and password i get connected correctly.But when i run the above code i get an error "Unable to connect to the remote server" Now i want to change the username and password.Please tell me how to do
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'm trying to get into an installation of v.6.5 to use with anotherserver and I need the following information:Database hostnameDatabase nameDatabase usernaneDatabase passwordIs this information available anyplace within the installation files?I'm not asked for uname and pwd to get into the database.Thanks!
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?
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 can't figure it out how to create a database with an username and a password. I'm using Visual Studio 2005 and Microsoft SQL Server 2005. Can someone help me out? Greetings,Persyn Bert.
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?.
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
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 :
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(); }
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.
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.

Is there any way to Remembering the username and password on report manager? I have set the credentials to "Credentials supplied by the user running the report" ... cant use the Windows credentials for some reasons...
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 .. :(
