Hi,
Is there any way of decrypting password value stored in sysxlogins table of SQL database?
Thx in Adv
Hi there,
I am having a table in Sql which has 2 columns which has data in encrypted format. It shows data in junk format (ascii format). But in frontend (tht is in software)it shows data in proper format. Can any one help me in decrypting data.
Thanks,
Regards,

CREATE TABLE TabEncr (
id int identity (1,1),
NonEncrField varchar(30),
EncrField varchar(30)
)
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'OurSecretPassword'
CREATE CERTIFICATE my_cert with subject = 'Some Certificate'
CREATE SYMMETRIC KEY my_key with algorithm = triple_des encryption by certificate my_cert
OPEN SYMMETRIC KEY my_key DECRYPTION BY CERTIFICATE my_cert
INSERT INTO TabEncr (NonEncrField,EncrField)
VALUES ('Some Plain Value',encryptbykey(key_guid('my_key'),'Some Plain Value'))
CLOSE SYMMETRIC KEY my_key
OPEN SYMMETRIC KEY my_key DECRYPTION BY CERTIFICATE my_cert
SELECT NonEncrField,CONVERT(VARCHAR(30),DecryptByKey(EncrField))
FROM dbo.TabEncr
CLOSE SYMMETRIC KEY my_key
What is the problem with this code. It works fine , inserting the value encrypted but when i try to decrypt ,it returns a null value. What is missing. I also tried with symmetric key encryption with asymmetric key. Result is same, returns NULL value. I am using SQL 2005
Happy Coding...
Hi!
I want to encrypt a whole column in my table and I do this with this SQL code:
OPEN symmetric key Sym_Key DECRYPTION BY certificate My_Cert
GO
UPDATE [My_demo].[dbo].[My-DemoList]
SET [Test_crypt] = encryptByKey(Key_GUID('Sym_Key'),[Test])
GO
CLOSE all symmetric keys
GO
And this seems ok but when I want to decrypt it with the view I have created it seems that I get a "rubbish" character between each "real" character.
So my questions is: What am I doing wrong?
Because if I do an insert like this
OPEN symmetric key Sym_Key DECRYPTION BY certificate My_Cert
GO
INSERT INTO [My-DemoList] (Test_crypt) VALUES(encryptByKey(Key_GUID('Sym_Key'),'1234567'))
GO
CLOSE all symmetric keys
And then use my view to look at the decrypted value that I put in its ok.
Many thanks in advance!
I find it weird when decrypting a column from a baked up database and restoring it to another database. Here's the scenario:
Server1 has Database1.
Database1 has Table1 with two columns encyrpted -- Card Number and SS Number
Encryption and decryption in this Database1 is perfectly fine. Records are encrypted and can be decrypted too.
Now, I tried to backup this Database1 and restore it to another server with SQL 2005 instance called Server2. Of course the columns Card and SS Numbers were encrypted. I tried decrypting the columns using the same command to decrypt in Database1, however, it returns a NULL value
Here's exactly what I did to create the encyprtion and decryption keys on the restored database:
-- Create the master key encryption
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'myMasterPassword'
-- Create a symetric key
CREATE SYMMETRIC KEY myKey WITH ALGORITHM = DES
ENCRYPTION BY Password='myPassword';
Go
-- Create Card Certificate
CREATE CERTIFICATE myCert WITH SUBJECT = 'My Certificate on this Server';
GO
-- Change symmetric key
OPEN SYMMETRIC KEY myKey DECRYPTION BY PASSWORD = 'myPassword';
-- I then verified if the key is opened
SELECT * FROM sys.openkeys
If I create a new database, say Database2 from that Server2, create table, master key, certificate, and symmetric key. Encrpytion and decryption on Database2 will work!
Any suggestions gurus? I tried all searches and help for almost 2 weeks regarding this issue but nobody could resolve this.
Thanks in advance!

I have a OLE DB Source that has a varbinary column of encrypted data. The sorce table is on a hosted SQL Server database where I cannot install a asymetric key. The SSIS package is running on a local SQL Server box that does have the asymetric key installed and working. Can you recommend the best way to transform this column is SSIS using a connection to the local SQL Server box that has the installed public key?
select @encryptedstuff = 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
SELECT CONVERT(nvarchar(50),DecryptByAsymKey(AsymKey_ID('rsakey'), REVERSE(@encryptedstuff), N'P4ssw0rd'))
Each row of the OLE DB Source contains a varbinary column with the ecrypted data. I need to to transform that one column and end up with a new record set that contains all of the columns from the OLE DB Source plus a new decrypted column.
Thanks,

I have following problem. I would like to provide to my STP encrypted data and decrypt them inside it. To decrypt the data I'd like to use DecryptByKey. Encryption should be made on the Win32/.NET client.
Unfortunately I cannot find the way to make the data understable between the both worlds. First how to assign the same key on the both side? Do I get the same key from
Code Snippet
create symmetric key MyKey with
algorithm=triple_des,
key_source='abrakadabra'
encryption by password='aaa'
and from
Code Snippet
string Key = "abrakadabra";
byte[] bKey = Encoding.ASCII.GetBytes(Key);
byte[] salt = new byte[8];
RNGCryptoServiceProvider rnd = new RNGCryptoServiceProvider();
rnd.GetBytes(salt);
PasswordDeriveBytes pdb = new PasswordDeriveBytes(bKey, salt);
TripleDESCryptoServiceProvider prov = new TripleDESCryptoServiceProvider();
prov.GenerateIV();
prov.Key = pdb.CryptDeriveKey("TripleDES", "SHA1", 168, prov.IV);
???
I have read somewhere that create symmetric key calls CryptDeriveKey, but I'm not sure.
The next point is the format of the output data. I have noted, that the output from EncryptByKey is 16 bytes longer (after stripping key guid and fixed 0x01000000) than the one from Win32/.NET application. I assume, that it can lie in the inserting of IV as the first block, but should not IV be only 64 bit long in the DES family of algorithms?
Neverthless I have not magaged to perform encrypted communication such way between SQL Server 2005 and client application. Is it possible at all?
Hi all,As all of you are aware you can Encrypt your Triggers/Stored Procedures/Views And Functionsin Sql Server with "WITH ENCRYPTION" clause.recently i came across a Stored procedure on the Net that could reverse and decrypt all Encrypted objects.i personally tested it and it really works.That's fine (of course for some body)Now i want to know is it a Known Bug for Sql Server 2000 and is there a permanent solution for Encrypting mentioned objects.Thanks in advance.Best Regards.

Im wondering how do you encrypt and decrypt a stored procedure within sql server 2000 ?
i want to be able to encrypt data been inserted / updated using triple des algorithm and then on select / read - decrypt it.
Does anyone know a solution / stored procedure on how to do this? any ideas.
Thanks
Paul..
Im also wondering if there is a away of doing this on the code side without using stored procedures (asp.net c#) i have been able to encrypt and decrpt to a string but unable to do it through the datagrid object (dataset) or a datareader..
Any tips / help would be helpful
Thanks..
i have a ms sql base which contains tables encrypted with EncryptByKey, who knows how to make me a script do save the encrypted tables to clear text pm me in ym : hgfrfv or msn : [URL], i have all the keys used on encryption and all those stuff.

View 2 Replies View RelatedHello,
In SQL 2000,
I have created a Stored Procedure as follows,
Code Snippet
CREATE PROCEDURE MyTest
WITH RECOMPILE, ENCRYPTION
AS
Select * From Customer
Then after this when i run this sp it giving me the perfect results wht i want, BUT when i want to change something in sp then for I am using the below line of code.
Code Snippet
sp_helptext mytest
But its displaying me that this sp is encrypted so you can't see the details and when i am trying to see trhe code of this sp from enterprise manager then also its not displaying me the details and giving me the same error,
So i want to ask that if there is a functionality of enrypting the sp code then is there any functionality for decrypting the Stored Procedure also,
or not,
If yes then wht it is and if NO then wht will be the alternative way for this,
?????
I am executing a stored procedure in one database (Database1) that pulls data from another database (Database2) that is the back end for a third party application. Some of the fields in that other database are now encrypted. I need to decrypt those fields but since the query is running in a database other than where the data lives (which is also where the symmetric key + cert lives), I am getting the following error: "Cannot find the symmetric key" Below is an example of what I am running in the stored procedure:
OPEN SYMMETRIC KEY [XXXXKey] DECRYPTION
BY CERTIFICATE [XXXX_CERT];
select CONVERT(Varchar(50), DECRYPTBYKEY( <ENCRYPTED FIELD> ))
FROM Database2.dbo.TABLE1
CLOSE SYMMETRIC KEY [XXXXKey];
What do I need to add to Database1 so the stored procedure can decrypt the data it pulls from Database2?
In SQL 2005, I've created a test scenario in AdventureWorks where I:
1.) Create a database master key:
IF NOT EXISTS (SELECT * FROM sys.symmetric_keys WHERE symmetric_key_id = 101)
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '<password>'
GO
2.) Create a certificate:
CREATE CERTIFICATE HRCert
WITH SUBJECT = 'Comments'
GO
3.) Create a symmetric key:
CREATE SYMMETRIC KEY CommentKey
WITH ALGORITHM = DES
ENCRYPTION BY CERTIFICATE HRCert
GO
4.) Add a test column to the HumanResources.JobCandidate table:
ALTER TABLE HumanResources.JobCandidate
ADD Comments varbinary(8000)
GO
5.) Open the symmetric key for use:
OPEN SYMMETRIC KEY CommentKey
DECRYPTION BY CERTIFICATE HRCert
GO
6.) Insert and Encrypt values ('Yes') to the newly created column:
UPDATE HumanResources.JobCandidate
SET Comments = EncryptByKey(Key_GUID('CommentKey'), 'Yes')
GO
-------
Great. Now all the textbooks say that, to view the column values in a decrypted state, you should:
SELECT CONVERT(varchar, DecryptByKey(Comments)) AS [Decrypted Comments], *
FROM HumanResources.JobCandidate
------
Great, I get it. But here's the rub. What is the best way to permanently decrypt the column and keep it in a cleartext state?
Running the following works, but keeps the column values in a varbinary (hexadecimal) state which is what we originally created:
UPDATE HumanResources.JobCandidate
SET Comments = DecryptByKey(Comments)
GO
But if I want to transform this varbinary(8000) column into a human-readable varchar column, the only thing I could come up with was a temp table solution:
UPDATE HumanResources.JobCandidate
SET Comments = DecryptByKey(Comments)
GO
DECLARE @temp varchar(1000)
SET @temp = (SELECT TOP 1 CommentsFROM Human Resources.JobCandidate)
CREATE TABLE #decrypt (Comment varchar(1000))
INSERT INTO #decrypt (Comments) VALUES (@temp)
GO
ALTER TABLE HumanResources.JobCandidate
ALTER COLUMN Comments varchar(1000)
GO
UPDATE HumanResources.JobCandidate
SET Comments = (SELECT Comments FROM #decrypt)
GO
DROP TABLE #decrypt
GO
--------
It works, but seems so inelegant to me.
Is there an easier way?
I have an encrypted column of data that is encrypted by a passphrase. The passphrase was encrypted by a symetric key in a key pair. The passphrase also is stored in a table. I can get the passphrase as needed to encrypt/decrypt the columns. I copied the production database to a new database for development. Subsequently I had to create a new symmetric/asymmetic key pair and recreated my passphrase with the new key pair. Now the passphrase will decrypt a text column but it will not decrypt two other columns which are of type varchar in the database. Here is an example:
DECLARE @pss varchar(30)
EXEC [dbo].[uspPassPhraseGet] @pss OUTPUT
SELECT DISTINCT contactid, uissueid, createdby, created_dt
,CONVERT(varchar(max),DecryptByPassPhrase(@pss, CONVERT(varchar(max),dbo.tbl_msg_app_legislativeinquiry.title), 1, CONVERT(varbinary, 23))) as title
,CONVERT(varchar(max),DecryptByPassPhrase(@pss, CONVERT(varchar(max),dbo.tbl_msg_app_legislativeinquiry.description), 1, CONVERT(varbinary, 23))) as description
,CONVERT(varchar(max),DecryptByPassPhrase(@pss, CONVERT(varchar(max),dbo.tbl_msg_app_legislativeinquiry.shortdesc), 1, CONVERT(varbinary, 23))) as shortdesc,
closed_dt, confidential, statusid, due_dt, deleted_dt,deletedbyid, highrisk, dbo.tbl_msg_app_legislativeinquiry.designator, dbo.tbl_ref_sys_status.description AS statusdesc
FROM dbo.tbl_msg_app_legislativeinquiry INNER JOIN
dbo.tbl_ref_sys_status ON statusid = dbo.tbl_ref_sys_status.ustatusid INNER JOIN
dbo.tbl_gbl_lkp_security ON uissueid = dbo.tbl_gbl_lkp_security.msgid AND
dbo.tbl_msg_app_legislativeinquiry.designator = dbo.tbl_gbl_lkp_security.designator
Like I said I can execute the uspPassPhraseGet stored procedure and I get my passphrase. It will correctly decrypt the dbo.tbl_msg_app_legislativeinquiry.description field which is great but the other two fields will not decrypt. When i copied the database over the encrypted fields do not display the same on the new database. The old database shows a box character followed by a bunch of junk (as expected). The new copied table on the new database shows only a single box (not the same as the original). Is there a known bug with copying a table with varchar fields that are encrypted to a new database? I tried to run a test and got the same result. I also tried to convert the varchar columns to text to see if that solved the problem and it didn't. The description field however is a text type column and it reads exactly as the original. The problem I think is that the Copy Database didn't actually copy my data correctly. How can I get the original encrypted data from the production into my development. I also tried just dropping the table and reimporting the table but that didnt take either. Scratching my head on this one.
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 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
I 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?

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,

I put this together to export the user name /password to a csv file to test my SP to output the user name/password.

I have an internal Project Management and Scheduling app that I wrote internally for my company. It was written to use MySQL running on a Debian server, but I am going to move it to SQL Server 2000 and integrate it with our Accounting software. The part I am having trouble with is the user login portion. I previously used this:
PHP Code:
$sql = "SELECT * FROM users WHERE username = "$username" AND user_password = password("$password")";
Apparently the password() function is not available when accessing SQL Server via ODBC. Is there an equivalent function I could use isntead so the passwords arent plaintext in the database? I only have 15 people using the system so a blank pwd reset wouldn't be too much trouble.
I am building a website in Dreamweaver. I have tried and tried to get a connection to SQL 2005. Everything works on the web except the stuff that requires the use of my SQL tables. With OPEN_Conn ="Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=master" I get an error at the bottom of my page saying this:
Microsoft OLE DB Provider for SQL Server error '80004005'
Invalid authorization specification
When I add a password and ID to the string the pages become very slow and I get this error:
Microsoft OLE DB Provider for SQL Server error '80004005'
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
Using windows authentication when logging into SQL Server doesn't have a user id or password so maybe I just don't know what to put there. I have tried a mix of all the passwords and ID's I use on this computer. Do I even have to have the user ID and password and if not how do I fix the first error? All help appreciated.

Hello ,
Is is correct that the 'sa ' passoword is stored in one of the files of the SQL Server and is easily readable if the location of the file is known ?
If not , then is the password encrypted when i try to connect to the SQL server on the Internet ?
Thanks.

I am designing a DTS package which i need to update every so often to change the name of the source file(it's a text import). Every time that i change this, then click save, the DTS job begins to fail, with password errors.

Is there anyway to "get in the backdoor" if you have installed SQLserver and assigned sa a password (no other users are set up with admin rights) and then forget what the password is.
In the online doc it says you have to reinstall SQL server....isn't there any other way to get in??? For instance in SYBASE you can log on to the console and "go thru the backdoor" and issue a command from there.
Please advise.
