Hi,
When I run the package it gives the following error warning.
Not sure how and where to fix this.
P.S. The package runs successfully and loads data but not sure why I get this error.
Thanks

Hi Guys.
I am looking for TSQL code for RC4 encryption and decryption.
I found VBcode for RC4 encryption, it will take atleast 2 days for me to go thru that and rewrite the whole code in SQL.
If anyone has the code, please provide me.
(I know sql does accept extended ASCII characters)
Thanks

Hi folks,
I'm trying to encrypt a small token of data on my client c# application and have it decrypted by SQL on the server side, the problem is i cannot find articles on the subject. I don;t really want to get involved with certificates but base the system on a simple symmetric key that is shared by both parties.
I'm attempting to use the TRIPLE_DES algorithm on both sides and thus far have used the decryptbypassphrase on the server side with the data encrypted on the client side by .Net with no initialization vector setup.
If anyone can recommend any articles or have example (client and server side) code for this situation it would be greatly appreciated.
Many thanks in advance
Simon

Does anyone know what my .net app guys need to share with me if encryption was done in the .net app but decryption needs to occur in certain sql queries? I read about master keys, certificates, symmeteric keys, algorithms etc but dont know how that stuff would carry over from the framework into sql. All I know is that the algorithm is AES_256, they must be adding authentication to the encryption and i know the hash algorithm, and symmetric keys are involved. Will they be sharing certain kinds of files with me that need to be registered in the db? Will I have to use CLR if I want the two worlds to come together?

Hi all.
The new feature of login encryption still tortured me and my company's fellow :(
We can't use the server's profile nor server's login audit functionality.
The reason is.. they do not want any additional feature to the server even if it's just a small task.
So..
I know that self signed certi generated whenever the MSSQL server started. My question is..
1. Where is that self-signed certification. Is it loaded to memory or physical hard disk.
2. Is there any special 'store' for this self-signed certification?
I tried to find this certi from all of my store using the certutil.exe but couldn't find this certi.
3. Is there any api that find and decrypt this login info?
Thank you.

Hi... I want to encrypt data using a symmetric key + certificate, but it appears anyone with simply "db_datareader" can view the decrypted data? Is this correct?
Recreation steps:
1. As a System Admin, log into a SQL 2005 Database Engine.
2. Create some login that you also have access to. Ensure it does not already exist, or inherit any permissions from some existing NT-group. (From here on out, I will refer to it as the "underpriveleged user".)
3. Create a new database of any name.
4. Run the following query against the database:
CREATE TABLE [dbo].[MyTable](
[MyColumn] [varbinary](50) NULL
) ON [PRIMARY]
GO
CREATE USER [DOMAINUserName]
FOR LOGIN [DOMAINUserName] WITH DEFAULT_SCHEMA=[dbo]
sp_addrolemember 'db_owner', 'DOMAINUserName'
5. Now open another SSMS and connect as that underpriveleged user.
6. Change the database to the name you provided in Step 3.
7. Run these commands as the underpriveleged user...
CREATE MASTER KEY ENCRYPTION BY PASSWORD='DbMK_pwd'
CREATE CERTIFICATE MyCertificate WITH SUBJECT='Some Text'
CREATE SYMMETRIC KEY MyKeyName
WITH ALGORITHM = DESX
ENCRYPTION BY CERTIFICATE MyCertificate
OPEN SYMMETRIC KEY MyKeyName
DECRYPTION BY CERTIFICATE MyCertificate
INSERT INTO MyTable(MyColumn)
VALUES (EncryptByKey(Key_GUID('MyKeyName'), 'MyValue'))
SELECT Convert(varchar,DecryptByKey(MyColumn)) FROM MyTable
CLOSE SYMMETRIC KEY MyKeyName
8. Now switch back to the System Admin session, and revoke most of the underpriveleged account's permissions...
sp_droprolemember 'db_owner', 'DOMAINUserName'
GRANT SELECT ON dbo.MyTable TO [DOMAINUserName]
9. Switch once again to the underpriveleged session, and run the following:
OPEN SYMMETRIC KEY MyKeyName DECRYPTION BY CERTIFICATE MyCertificate
SELECT *, Convert(varchar,DecryptByKey(MyColumn)) FROM MyTable
CLOSE SYMMETRIC KEY MyKeyName
Why does this work? The user only has select access against the table, and no explicit permissions to the certificate or key. I have even disconnected as this user, tried again, restarted SQL Server... it is still able to decrypt the text.
Or what should I be doing to ensure only those with access to the key/certificate can decrypt the cipher text?

However, the return data just contains nulls, instead of the original decrypted data. You can see above that I deleted the certificate, but then restored the certificate from backup. However, it doesn't work.

Hi there,
Using symmetric keys and certificates in SQL2005, can one assign users permission to only decrypt or encrypt data?
Reason would be say data capturer and data reader type roles. I tried to create some with the GRANT CONTROL and GRANT VIEW for certificates and definitions on Symmetric keys, but havent been to successfull.
Would be great if someone here can offer some advise on it, and if it's possible using SQL rights.
thanks

Hi,
I,ve been searching the forum for answers to this error but with no luck:
Failed to decrypt protected XML node "DTSassword" with error 0x80070002 "The system cannot find the file specified.". You may not be authorized to access this information. This error occurs when there is a cryptographic error. Verify that the correct key is available.
Setup:
I'm running the packages from the SQL Job Agent - the packages are stored in the file system. The agent is using a proxy account to get the right permissions. I know this because the job has run for severel weeks without errors. The package is calling other packages and is using configuration files. It was actually more than on job that failed (with the same error) - but not all the jobs.
Now it is saying that it can not "find the file specified" - what file would that be? - I'm wondering if it is a package file or a configuration file or maybe another file. It dosn't give me any other information to where the problem is.
Any help is appreciated!
Regards
Simon

I suppose that some of the answer to my question may be found in that topic, but I haven't made much progress.
I have a text field in a SQL 2000 database that contains the text output (EncryptedData) from the EncryptedXML.Encrypt(xmlDoc.DocumentElement, certificate) method in .Net 2.0 (C#). The data looks something like this:
<?xml version="1.0" encoding="utf-8"?>
<EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element" xmlns="http://www.w3.org/2001/04/xmlenc#">
<EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes256-cbc" />
<KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#">
<EncryptedKey xmlns="http://www.w3.org/2001/04/xmlenc#">
<EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5" />
<KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#">
<X509Data>
<X509Certificate>[A Bunch of jumbled characters]</X509Certificate>
</X509Data>
</KeyInfo>
<CipherData>
<CipherValue>[A Bunch of jumbled characters]</CipherValue>
</CipherData>
</EncryptedKey>
</KeyInfo>
<CipherData>
<CipherValue>[A Bunch of jumbled characters]</CipherValue>
</CipherData>
</EncryptedData>
I have since imported the Public and Private key from the .Net app into SQL Server. I can use the EncryptByCert and DecryptByCert functions to verify that the key pair is compatible. However, I can't figure out how to apply them to the encryptedXML that my friendly .Net developers are dumping in the DB. Whenever I use the DecryptByCert function on any of the "[A Bunch of jumbled characters]" strings I just get NULL.
Does anybody have some insight?

Hi All,
I'm new to SQL Server 2005 encryption security. I developed a simple login form using .NET 2 framework. I'm encrypting the user's password on the execution of the INSERT statement using SQL Server EncryptByCert(Cert_ID('abc'),'password').
My only concern is that of decrypting the password on the execution of the SELECT dtatement in a stored procedure using the DecryptByCert(Cert_ID('abc'),val,N' certificate password'). Anyone who has rights on executing that particular stored procedure in SQL Server can easily return the user's password.
Can I still use the SQL encryption, whilst the login application handles the decryption (meaning I embed the DecryptByCert in the application ).
If anyone has other ways of implementing this please forward them? (I preferable would like to store all the certificates, private keys, etc on the database side )
Thanks,
Matt

We're encrypting a column of Social Security numbers. Developer needs to execute a query -->similar<-- to:
Select <bunch of columns>
From dbo.People p
Where p.SSN = @Input_SSN_Param --I know this won't work.
If we write the where clause like
Where DecryptByKey(p.SSN) = @Input_SSN_Param
Won't every SSN in the table be decrypted? Seems like a bad idea, performance-wise.
Should I/we add a column to hold a hash of the SSN; and use the hash for comparisons?
