Howdy!
Couple quick questions:
1) How much does setting encryption cost in terms of speed of querying and cpu usage?
2) If encryption is not set, is the password "encrypted" when its sent with the initialization routine?
Thanks in advance!

I currently have a login page in asp.net 2.0 linked to a SQL 2005 database table that holds the usernames and passwords. At present, I am on an "honor system" where I do have access to the passwords of the other users but would like to change it so that I cannot know what the users' passwords are. Thank goodness that there is no personal information within the pages and the logins were created to keep a log of who logs in and what not. However, I would like to soon hold more personlized information, hence the need to encrypt each user's password even from myself.
I have read up on Symmetric Encryption for SQL 2005 but I would like to know if there is anything else available, any good proven methods that someone else has already tried.
Also, while testing out Symmetric Encryption, I noticed that I have to supply the encryption password for the decryption. However, if I know what the password for the encryption/decription is, does it not defeat the purpose of having the encryption at all, in terms of the "Admin" having access to sensitive information? Just curious if I understood the concept correctly or not.
Thanks in advance to all.
I have created two user defined functions for encryption and decryption using passphrase mechanism. When I call encryption function, each time I am getting the different values for the same input. While I searching a particular value, it takes long time to retrieve due to calling decryption function for each row.
best way to encrypt and decrypt using user defined functions.Below is the query which is taking long time.
SELECT ID FROM table WITH (NOLOCK)
                    WHERE dbo.DecodeFunction(column) = 'value'
When I try to use symetric or asymetric encryption, I am not able to put "OPEN SYMETRIC KEY" code in a function. So, I am using PassPhrase mechanism.
I'm trying to protect a package... using an owner password.
After I create an owner password and generate a dts command line from

DTSRun /S "svr-eqanalysis" /N "OrgExtract Rename" /M "password" /G "{2E2B6F07-0E56-4212-A894-B85A4EAA6C8C}" /W "0" /E
We can not remove the builtin administrators group from the machine
therefore system admins that want to poke around into our work can do so....
any suggestions......

Alright, so I have a basic search function to look through a field in my database which is decided by a query string. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseConnectionString %>"
SelectCommand="SELECT * FROM [Employee] WHERE ([Responsibilities] LIKE '%' + @Responsibilities + '%')"> <SelectParameters> <asp:QueryStringParameter Name="Responsibilities" QueryStringField="q" Type="String" /> </SelectParameters> </asp:SqlDataSource> But, I'd really like to fix it using parameterized SQL queries, so that people aren't dropping my tables. >_>I've been lookin' around for some code on how to do this in C#.NET, and most of them seem to look like this: SqlConnection objConnection = new SqlConnection(_ConnectionString);objConnection.Open();SqlCommand objCommand = new SqlCommand( "SELECT * FROM User WHERE Name = @Name AND Password = @Password", objConnection);objCommand.Parameters.Add("@Name", NameTextBox.Text);objCommand.Parameters.Add("@Password", PasswordTextBox.Text);SqlDataReader objReader = objCommand.ExecuteReader(); My problem is that I don't know how really know how to go from my code to this code... I mean, would I throw the latter in my backend code and call what it returns as a string, would I entirely replace my Datasource and do soemthin' with the code? Any help, in the form of tutorials or just straight up tellin' me here, would be greatly appreciated.Thanks. =D
Hello all,
I'm using the following code to query my database...
public static void InsertsComments(string Comments, string TagID, string UserName) { SqlCommand cmd = new SqlCommand("insert into TG_UserComments (Comments, Tag_ID, UserName) values (@Comments, @TagID, @UserName)", conn); conn.Open(); cmd.Parameters.Add(new SqlParameter("@Comments", Comments)); cmd.Parameters.Add(new SqlParameter("@TagID", TagID)); cmd.Parameters.Add(new SqlParameter("@UserName", UserName)); cmd.ExecuteNonQuery(); conn.Close();
}
My first question is, should I be making @Comments, @TagID, @UserName a little more cryptic? Liks @CommDBQ23 or something? Does that make it safer?
Also, I'm going to use stored procs query the database, instead of how I'm doing it above. What would I need to change in the code to do this? Obviously I'd need to call a stored proc on the server, but can I still protect myself from sql injections with the above code? Is there anything else I should be doing to secure my application at this level?
Thanks!

Hi all,
I've developed a database driven web app in ASP.NET and ready to deploy to my customer. However, I'd like to know is there any way to encrypt / protect the source of my stored procedure and view in SQL Server? My web app make heavily use of SPROCs and DB Views and I don't want my client to view / alter it, compared with the web app, I can compile it into a .DLL file and remove all business logic, any similar thing in SQL world?

I'm having problems with ftp tasks in SSIS packages where protectionlevel=EncryptSensativeWithPassword. I've used this many times with no problems, but now that I've upgraded to 2005 SP2, It's not working as before.
I have a functioning SSIS package with an FTP download. It works fine on my workstation in the developement environment.
If I load it to the SQL server using Server Manager Studio under my account, I cannot run the package from the server when logged on as Administrator, nor can I schedule it to run under the SQLAgent account as a job. The error mesages are: Unable to connect to FTP server using "FTP Connection Manager" and "The password was not allowed". Obviously the password being sent to the ftp server is wrong, but it was right under developement. Further more, If I log into the server under my account the package runs fine!
If I load the package while logged in as administrator, I can only run the package as administrator. And of course, if I load the package as SQLagent, I can only run the package as SQLagent.
This is not how SSIS packages were operating before I upgraded! In fact I've reloaded some existing packages and found that they now have inherited this behavior (after they have been re-imported)
It looks to me like SSIS is using the EncryptSensativeWithUserKey option, instead of the EncryptSensativeWithPassword option. I'm not sure how to confirm this, short of using a packet sniffer to watch the ftp traffic.
I could switch to PackageConfigurations, but I was happy with the EncryptSensativeWithPassword option, which seemed appropriate for our operation.
Does anyone have any ideas what could be going on, or any suggestions to troubleshoot this? How can I tell if password is encrypted or not?
Hi All,
I would like to build a standard BI solution based on MS SQL2008 - integration services, analysis service and reoprting services.
This stardard BI solution can be distributed to multi customers - however I want to protect the source code so customers cant access the code.
I would like to be able to ecrypt or protect the solution - so the customer only get the "executable" but they cant access the soruce code. This is to protect my intellectual property.
Kindly advise if there are any way to achive this objective in SQL2008.
I did some research in SQL 2005 long time back - but I was unable to find resolution to protect the intellectual property.
I would be extremely pleased to get some good advise on how to protect IP in SQL 2008.
Thanks heaps, Thomas
we are using sql server 2000 and it's on a remote system. One of the databases "Dbase1" went to Suspect mode. when we checked both the .mdf and .ldf files were missing from the Server. they were not there at all. Is there any way to recover the databse. To make it more secure what are the possibilities which we can use so that in future we should be able to restore our databse.
Thanks in advance

I have a question that I am sure that others have had to deal with in the past. I am writing business requirements for a web application that stores names, addresses, etc. I have hit a bit of a problem in design with allowing users to enter data they need, like the name O'Brien, and developers saying that allowing the single quote in a field could allow for an injection attack.
Developers want to strip out single quotes when they occur in the data, however the users are insistent that names and addresses that have single quotes in them are shown properly.
Is there any middle ground so that the system can be built to avoid an injection, but still allow data to be entered as intended.
I just installed SQL7.0 on a windows 98 machine. When I go to register a new database, I get the following message.

Help - what else
Hello everyone,
Can someone recommend me the most efficient protection level for SSIS
packages for my environment? I've been doing some reading on this lately, but can't really decide which one to use. The Rely on server storage for encryption (ServerStorage) seems interesting, but I'm unsure if that would work on my environment (Windows Authentication).
Currently I'm saving my packages to my dev server under "Encrypt sensitive data with user key" Protection level, but seems like the passwords for the FTP Connection for instance doesn't get saved when I deploy my package to the server.
Our environment consists of 2 dev servers + 2 prod servers with windows authentication, our SQL Agent Account is a domain account with local admin rights and sysadmin rights on the SQL Server and we try to use proxy accounts to access network resources instead of giving the agent access to everything.
This is what I found on MS's web site.

All:
I am aware that I am raising an issue/question that has quite a number of ancestors in this forum. In reviewing some of the threads I still believe my situation has a bit of a twist; but that could just be me.
The process I used until a change I made recently worked just fine. A handful of my packages connect to our ERP system that only supports an ODBC connection. I set the Protection Level to the default, and then deploy the packages to the server. I use an agent to run the jobs that include these packages as steps. I have hardcoded the userID and password in the SQL jobs and so they have run fine.
In an effort to reduce maintenance on the packages I decided to run the packages from the File System instead of deploying them to the server. Now, the packages are not running as I have not changes the Protection Level yet. I did test running one of the packages using a Proxy I have created but that does not work either.
Based upon what I have read it appears that the first thing I need to do is change the Protection Level to DoNotSaveSensitive. How do I then pass the ID and password to the agent?
a. Create a confirguation file?
b. Create a package template?
c. Both of the above
To reiterate I do not wish to deploy the packages to the server; I prefer to run the packages from the File System. Further, I just have one box on which everything happens; there are no migration issues across servers.
Some insights from this group will be greatly appreciated.
Thank you!
Hello,
I have a package that contains a connection manager to a DB2 source. The password is configured within the connection mananger. The configuration string was included in the package configurations (SQL Server). The package is saved in VSS, and locally on my hard drive.
When a colleague attempts to open the package is Visual Studio (from VSS), He gets a message similar to the following.
Error 1 Error loading 'Geac_RK502.dtsx' : Failed to remove package protection with error 0x8009000B "Key not valid for use in specified state.". This occurs in the CPackage::LoadFromXML method. . C:Documents and SettingscdunnMy DocumentsVisual Studio 2005ProjectsGeac_RK502Geac_RK502Geac_RK502.dtsx 1 1
I'm very sure the package protection level was to encrypt sensitive data with user key. After he ran into this problem, I tried again to open the package from my computer (the machine that the package was created on) and now I get the same message. If I attempt to open the package anyway, I first get a message that there were errors in the package while it was being loaded, and that the package might be corrupt. After that message, I get one that states the document contains one or more extremely long lines of text....do you still want to open the file. If I click yes, the package opens read only with the following message:
Microsoft Visual Studio is unable to load this document. Failed to remove package protection with error 0x80090008. "Key not valid for use in specified state". This occurs iin the CPackage:LoadFromXML method.
I'm looking into more information about package protection. What can I do to avoid this problem, and what protection level should I be using so that my colleague can open the package? How can I correct the problem with this particular package, and have the package open?
Thank you for your help!

Hi all,
I have a problem while trying to deploy my packages that are configured in ProtectionLevel=EncryptSensitiveWithUserPassword
I use the Deployment Utility to deploy my packages. I set the password when deploying and the deplyment works fine. But I run the packages I have the following error : " Failed to decrypt an encrypted XML node because the password was not specified or not correct."
Did I miss something ?
How can we control the accesses to a SQL Server that has been deployed on customer site? Basically, we do not want user to log in the database server, even as sa, except through our application.
Any recommendation?

For those of you who have had a hard time like me trying to figure out using Protection level for an SSIS package whilst deploying the package via the SQL Server Agent, here is a piece of advice:
Firstly the protection level is set by Default to - "EncryptSensitivewithUserKey".
The encryption actually takes place only if you have things like - passwords etc..
From my experience - using both - "EncryptSensitivewithUserKey" and "EncryptSensitivewithPassword" Security features have turned out to be unreliable when deploying through SQL Server Agent (even while using a Proxy account having all previliges).
This is it seems because of issues with the user who created the package being different from the user who deployed the package. (which is really ridiculous).
So I used the ProtectionLevel - "DontSaveSensitive" - which means it is not going to encrypt anything in the package and so ur sensitive information would be blank. You would have to then supply your password etc using a configuration XML file. - using SSIS "Package configuation" in your menu....
This has been the most reliable way of solving the whole problem with encryption.
bear in mind that you might want to put the XML file in a secure location to which no one else has access to.
Thanks

I am currently designing a SSIS package that will migrate data from Syabse to Sql server. If these packages are to be deployed to file system (as this is one time run for migrating data) or to SSIS catalog or to Sql server.
Also, I have not changed the default protection level value in packages during design time and would like to know if I have to change it while handling the deployment using DTutil (yes, i need to deploy & execute using command line utilities).
Please note that I do not have access to PROD, UAT environments and deployment team will use my BAT file that is expected to deploy and execute the packages.
Hi,
Can anyone explain to me why my ssis packages will not work when DontSaveSensitive protection level is selected? My package configurations are set as SQL server configuration type, and I have a table in a database that contains all the sensitive information (passwords and such). If I select "EncryptSensitiveWithUserKey" everything works, but I will be the only one able to execute the packages (not good, I need others to be able to execute them as well).
The error I'm getting tells me that the connection is not configured correctly or I may not have the right permissions on the connection.
My guess is that the DontSaveSensitive drops the passwords, but when I edit the data source and re-enter the password, it still does not work. Also, the database table I use that contains the sensitive data is not affected, all data remains.
What the fudge is going on here? I'm a newbie at this, can someone help me out?
I made a merge replication and sucessfully connected with mobile device. Everything works fine. Because I wanna try asynchronous synchronization (which won't stop my application executing when subscribing) I read How to example from MSDN :
http://msdn2.microsoft.com/en-us/library/ms172391.aspx
But there is a problem with creating SyncStatus class object. I can't get into it and I can't create. maybe some reference will help? (I use reference to SQLServerCE). This error stoped my work for now, so I am waiting for some answers.
And if it's simple resolution for this problem - sorry. I just started programming applications for Mobile Devices.
Best regards. Maciek Wysocki
