Hi,
Does anyone know which algorithm is being used to encrypt the passwords in the sysxlogins for SQL Server 2000? I've been googling for some time..but I can't seem to find this information. Please help.
Many thanks,
Leona
Hi,
I need know what algorithm to encrypt the password into Security Directory, if anybody know the name.
Thanks
I have a package protected by a password - I am already unhappy that to get it to use the configuration file to change connection strings for the production servers I have had to hardcode the password into the config file - very insecure!
However, the package now deploys correctly to the production server and will run from there OK, but NOT if scheduled as a SQL Server Agent Job. Thus is because however often I edit the command line to include the password after the DECRYPT switch (which it has prompted me for when I click on the command line tab), the Job Step will not retain it.
If I open it up after I have edited it and closed it, the password has disappeared.
I know that if I run dtexec plus the code in the Command Line tab (with the password), the package runs OK.
This is driving me insane!
I have read all the other posts and so I tried replacing the SSIS package step with a CmdExec step and pasting that code into there - then I get an OLEDB error..
The code I use is:
DTEXEC /SQL "ImportRateMonitoringTables" /SERVER servername /DECRYPT password /CONFIGFILE "D:Microsoft SQL ServerSSISDeploymentsRateMonitoringImportTasksDeploymentImportRateMonitoringTables_Production.dtsConfig" /MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING E
and I get
SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x8000FFFF
although the same code executes perfectly from a command prompt.
Please does anyone have any experience with a similar problem and if so, how did you get round it?
Thank you
Hello,
I do have one application in VC++ as a Front End & Sql Server 2005 as a Back End.
i want to store my username's password in encrypted format, means no one can able to see the password.
Ex:- if i enter password as a "xyz" then it should be save as a some encrypted [base 64 encoding scheme] format.
Can any one help me out?
Thanks

Hi,
I would like to encrypt and decrypt password in my own tables
select stuff
from mytable
where password = decrypt('ackdo$$y')
How can I do this? Is there any decrypt or crypt function?
thanks,
I am setting up several isql job in Enterprise Manager and as a cmdexec job I need to pass the user id and password( -P). I shtere any way not to pass this as text and perhaps hide/encrypt it since any one who opens the task scheduler and looks at the job can read the password?
Thanks.

Hi,
I have a login table with username and password as attributes. I need to encrypt the password using stored procedure and then save it in the database. And also while retrieving the password, decrypt using the same stored procedure and get the original text.
I dont know how to do it in SQL server 2000.
Please help me on this. Its urgent.

How to find hash algorithm and salt value for sql logins in sql server 2005.
View 7 Replies View RelatedI am trying to learn how to store a web form password and than check it when the user log in. So far none of the code I can find works.
Why the following test does not work and what the correct code should be?
Insert Into [user]

GO
Why does the following produce no rows?
SELECT *
From [user]
Where HashBytes('SHA1', password) = HashBytes('SHA1', 'bob')

Hi there ,1. i have a database and i want to encrypt my passwords before storing my records in a database plus i will later on would require to authenticate my user so again i have to encrypt the string provided by him to compare it with my encrypted password in database below is my code , i dont know how to do it , plz help 2. one thing more i am storing IP addresses of my users as a "varchar" is there a better method to do it , if yes plz help me try { SqlConnection myConnection = new SqlConnection(); myConnection.ConnectionString = ConfigurationManager.ConnectionStrings["projectConnectionString"].ConnectionString; SqlDataAdapter myAdapter = new SqlDataAdapter("SELECT *From User_Info", myConnection); SqlCommandBuilder builder = new SqlCommandBuilder(myAdapter); DataSet myDataset = new DataSet(); myAdapter.Fill(myDataset, "User_Info"); //Adding New Row in User_Info Table DataRow myRow = myDataset.Tables["User_Info"].NewRow(); myRow["user_name"] = this.user_name.Text; myRow["password"] = this.password.Text; // shoule be encrypted //not known till now how to do it myRow["name"] = this.name.Text; myRow["ip_address"] = this.ip_address.Text; myDataset.Tables["User_Info"].Rows.Add(myRow); myAdapter.Update(myDataset, "User_Info"); myConnection.Close(); myConnection.Dispose(); } catch (Exception ex) { this.error.Text = "Error ocurred in Creating User : " + ex.Message; }

I have connected to Database using my credentials by checking remember password option. After few days I forgot my password. How can I recover the password as SQL remember it. Is there any way to recover my password instead of resetting it.
View 3 Replies View RelatedI am receiving the following error message when attempting to create a new SQL Authenticated login id.
Password validation failed. The password does not meet the requirements of the password filter DLL. (Microsoft SQL Server, Error: 15119)
I have four servers all running SQL Server 2005 SP2 on Windows 2003 Ent. SP1. Of the four servers, only one received the above error message using the same TSQL below.
CREATE LOGIN TEST_LOGIN WITH PASSWORD = 'pvif9dal' MUST_CHANGE, CHECK_EXPIRATION = ON
All four servers are in the same domain, which if I understand correctly, the password policies are therefore inherited at the OS level by the domain. The password being used is within the password policies of the domain.
Any ideas as to a root cause?

Does any have a algorithm that can divide A into B without using the divide
sign (/) or the multiplication sign ( * ).
I am new to DM and I am not sure which algorithm would be best to use.
I am trying to build a custom comparitor application that companies can use to compare themselves against other companies based on certain pieces of information. I need to group a company with 11 other companies based on 6 attributes. I need the ability to apply weightings to each of the 6 attributes and have those taken into consideration when determining which 10 other companies each company is grouped with. Each group must contain 11 members, the company for the user logged in and 10 other companies that it will be compared against.
At first I thought that clustering would be a good fit for this but I can not see a way to mandate that each cluster contain exactly 11 members, I cannot see a way to weight the inputs, and I think each company can only be in one cluster at a time which do not meet my requirements.
Any help will be greatly appreciated!
Well, i have read in claude seidman book about data mining that some algorithm inside in microsoft decision tree are CART, CHAID and C45 algorithm. could anyone explain to me about the tree algorithm and please explain to me how the tree algorithm used together in one case?

On the login prompt for Report Server, there is a checkbox option to "Remember my Password." I check this, login successfully... but when returning to the Report Server, I am again prompted for the password, although the user name is saved. No matter how many times I do this, the password will not save in IE7. I have tried this on 3 different computers with IE7. In IE 6, I do not even get the checkbox as an option, just the user name/password prompt. In Firefox, the password saves fine. Any ideas what would be causing this?
Thanks,

Hello,Do you know if the algorithm for the BINARY_CHECKSUM function in documentedsomewhere?I would like to use it to avoid returning some string fields from theserver.By returning only the checksum I could lookup the string in a hashtable andI think this could make the code more efficient on slow connections.Thanks in advanced and kind regards,Orly Junior
View 3 Replies View RelatedWhat kind of algorithm does the MAX command uses? I have a table that I need to get the last value of the Transaction ID and increment it by 1, so I can use it as the next TransID everytime I insert a new record into the table. I use the MAX command to obtain the last TransID in the table in this process. However, someone suggested that there is a problem with this, since if there are multiple users trying to insert a record into the same table, and processing is slow, they might essentially come up with the same next TransID. He came up with the idea of having a separate table that contains only the TransID and using this table to determine the next TransID. Will this really make a difference as far as processing speed is concerned or using a MAX command on the same table to come up with the next TransID enough? Do you have a better suggestion?
Thanks
Hi,

Thanxs for any info.
Hi All!
I have few questions regarding Clustering algorithm.
If I process the clustering model with Ks (K is number of clusters) from 2 to n how to find a measure of variation and loss of information in each model (any kind of measure)? (Purpose would be decision which K to take.)
Which clustering method is better to use when segmenting data K-means or EM?
Thanks in advance!
Hi.
Does anyone know of or where I can find implementation of these C# algorithm /class libraries:
a) RLS - Recursive Least Square algorithm?
b) MWAR - Multi-resolution Wavelet Auto-regresive algorithm?
c) AR - Autoregresive moving awerage algorithm?
d) EWMA - Exponentially Weighted Moving Average
The .NET framework System.Math class do not seem to have these libraries.

hi,
i am using sqlserver2005 as back end for my project.
actually we developing an stand alone web application for client, so we need to host this application in his server. he is not willing to install sql server 2005 edition in his sever so we r going by placing .mdf file in data directory of project.
but before i developed in server2005 i used aes_256 algorithm to encrypt n decrypt the pwd column by using symmetric keys.it is working fine.
but when i took the .mdf file of project n add into my project it is throwing error at creation of symmetric key that
"Either no algorithm has been specified or the bitlength and the algorithm specified for the key are not available in this installation of Windows."
please suggest me a solution
Hi,
i'm making my master thesis about a new plug-in algorithm, with the LVQ Algorithm.
I make the tutorial with the pair_wise_linear_regression algorithm and i have some doubts. i was searching for the code of the algorithm in the files of the tutorial and i didn't saw it. I have my new algorithm programmed in C++ ready to attach him, but i don't know where to put him, in which file i have to put him to start to define the COM interfaces? And in which file is the code of the pair_wise_linear_regression algorithm in the SRC paste of the tutorial?
Thanks

I am trying to predict Revenue gererated by each Person.
My Input like this:
Month Person Revenue
-----------------------------------------
20050101 Person1 $1000
20050101 Person1 $2000
20050201 Person1 $1000
20050101 Person2 $5000
20050201 Person2 $2000
20050201 Person2 $3000
Obviosly for Person1 and 200501 I expect to see on MS Time Series Viewer $3000, correct?
Instead I see REVENUE(actual) - 200501 VALUE =XXX,
Where XXX is absolutly different number.
Also there are negative numbers in forecast area which is not correct form business point
Person1 who is tough guy tryed to shoot me.
What I am doing wrong. Could you please give me an idea how to extract correct
historical and predict information?
Thnak you,
Tim.
