hi,
I am a new user to SQL convert my business application from VFP. I am bulding my new application depending on stored procedures. My questions as follow:-
- Is there a way to stored procedures encryption?
- How to products my data structure
regards
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 have to encrypt my data in sql2005 database using assymetric key encryption which i have done properly.But i have a doubt that while writing stored procedure i have to provide key information in it , that will be visible to everyone then whats the use of taht encryption. Can anyone tell me how can i write stored procedure without providing key information in it.

I am 99% sure SQL Server 7.0 cannot encrypt data in an individual column. Can anyone tell me whether I am right or wrong?

I need to do this with some of the fields, like credit card number. My sql server acts as backend database server for IIS servers.
Your help is greatly appreciated!

Hi,
I am looking for a way to encrypt a column in my SQL Server Table. I have been looking in the books and have not found anything. Any ideas of how to do it?
I need assistance on how to encrypt the data in a column.

We need to set up a data export process from a SQL DB.
The output (be it XML, Text Files or whatever) needs to be encrypted before it is FTPd somewhere.
Is there support for encrption in SSIS? How / where in the package designer would you achive this?
Thanks in advance.

The error in the subject line "The property 'Use Encryption for Data' is not supported" is encountered when running a DTS package via a job step in SQL Server 7.0. The problem is not encountered when executing the DTS package interactively via Enterprise Manager from my PC. When I view the Advanced Properties of the OLE DB driver from Enterprise Manager on my PC, I notice a Use Encryption for Data Property. When I view the Advanced Properties of the OLE DB driver from Enterprise Manager on the Server, the Use Encryption for Data Property does not appear. Service Pack 3 for SQL 7.0 is installed on both my PC and on the SQL Server. I suspect this Property difference for OLE DB could be related to the fact that I installed Enterprise Manager for SQL 2000 on my PC at one time and then uninstalled. Any ideas how to correct this situation?
View 1 Replies View RelatedIs there any way to encrypt the sql server mdf and ldf data files in SQL Server 2005 without using EFS or creating an additional system user? Only one application which has the password embedded (i know this is a security risk) should be able to connect to the database and access the mdf and ldf files.

My current experience is with access and sql2000. In my current application, I compress/encrypt my data prior to storing in my database. Does the new verion of sql support compression/encryption and if so can you please point me to any links which discuss.

Hi,
I would like to encrypt data in my database. I want encrypted column value to be viewable only for certain group of users. Users that has access to my database doesn't meant they can access to my encrypted data.
Currently, I am using the following "approach" as my key management.
create master key encryption by password= 'MasterKeyPass'
CREATE ASYMMETRIC KEY MyAsymmKey AUTHORIZATION MyUser
WITH ALGORITHM = RSA_1024
ENCRYPTION BY PASSWORD ='MyAsymmPass'
CREATE SYMMETRIC KEY MySymmKey WITH ALGORITHM = DES
ENCRYPTION BY ASYMMETRIC KEY MyAsymmKey
My data will be encrypted using Symmetric key MySymmKey.
User who want to access my data must have MasterKey and MyAsymmKey password.
Is it OK? Any better way?
Thank you
Hi.
I have a SQL Server 2000 database that contains information I would like to encrypt. The information is a field inside a table, and I would like to encrypt this information using a key, and decrypt it in my asp.net application using that key and use the decrypted data.
Please tell me how this can be done, or direct me to an article or a link on the subject.
Thanks in advance.
I know there is no native encryption in SQL2K, but what 3rd party encryption tools would other forum members recommend from experience? I am required to encrypt data for PCI compliance.
Thanks

We have a large VMWare environment with HP SAN, and 2 datacenters - primary and DR, with SAN based replication between them.We also backup databases to tape via Commvault and send them off-site using a vendor.TDE protects data at 'rest', meaning, (that if it wasn't implemented, and) if someone got a hold of our physical .mdf/.ldf files, or our .bak's, or tapes, they could recover the data.

I need to encrypt certain fields of tables with minimized changes required to my application. I want the database only available to my application so I want to use password to protect the encryption key.
Currently, in SQL 2005, I created view and use INSTEAD OF trigger to encrypt/decrypt data to underlyer table. I also having code at application startup, pass my password to a stored proc to open these key so that my view can encrypt/decrypt data accordingly.
I read some posts mentioned that SQL 2008 supports transparent data encryption. May I know how does it help in my case?
Please advice.
Thank you
Hello,
I store data in an .mdf file (I use SQL server 2005), because this way it's easier to move the application from one machine to another.
I've faced a problem with the encryption of the database.
Is there a possibility/way to encrypt a database file so that, if someone else finds/copies the mdf, he/she won't be able to read it.
I thought about encrypting the string values of the tables itself and decode them inside the application and encide when Inserting, but why inventing somehing that might already exist.
Thank you.
One of my client requires TDS for all databases. My BI product has reports with OLAP Cube as data source.

Hi,
I have an encrypted SQL Server 2005 database. Data is encrypted and decrypted using the encryptbykey and decryptbykey statements. I would like to allow the end user to be able to build adhoc reports using the Report Builder. I can't figure out how to decrypt the fields as they are dragged onto the report layout. Does anyone have any insight on how to accomplish this, or is it even possible?
Thanks,

I have a question regarding Transparent Data Encryption. I have enabled TDE on a database using the below steps:
1. Create a master key encryption by a password.
2. Create a certificate in the the user database named 'TDE_Test' protected by the master key.
3. Create database encryption key 'TDE_Test' using the certificate created in Step 2.
4. Enable encryption by using the command 'ALTER DATABASE
TDE_Test SET ENCRYPTION ON'
I understand that if I need to copy this TDE encrypted database to a different SQL Instance, I have to copy the certificate from the source Instance to the destination Instance.Now my question is, do the Service Master Key and Database Master Key come into the picture here anywhere?
Are these related to TDE in any way? Do I have to take regular backups of the Service Master Key & Database Master Key as part of regular maintenance for the SQL Instance that has a TDE encrypted database?
Data encryption and database restores.
1. When using data encryption on a 2 node active/passive cluster does it make any difference which server the sqlserver is running on when encrypting or dcrypting data?
2. When restring a database to a different server with encrypted data is the data decrytable or is it lost?
I read a couple of articles related to encryption topic in this forum and I feel that's really helpful I don't know if anyone has some knoeledge about the encryption issues in replication and clustering environment. I read some documents from Microsoft web site that explains how to move an encrypted database from its original server to another new server instance. That cause a lot manual works, if the database master key has been encrypted by the original service master key and you still want to enjoy the auto-open feature in the new environment. As we know the Microsoft SQL Server 2005 has a hierarchy encryption key structure and its top level service master key is really service oriented. For what kind of mechanism or set up, Microsoft makes their encrypted database working smoothly and automatically in a clustered and replicated infrastructure. Is that possible to sacrifice the security a bit by dump the service master key for database master key and make database more portable? I search the web site all the way, but couldn't find the related topic. Anybody has a good idea or experience to share?
Thanks,
In cases when the SSIS package has to be deployed in SQL Server, when we use ProtectionLevel ="server storage" while creating SSIS Catalog, does it use TDE? or Database Standard Encryption? if the database is using TDE?

View 4 Replies View RelatedHi,
I have a central database server that is runnning on SQL 2005 standard edition and Windows server 2003 standard as OS.
I realise that I can use SQL statements to encrypt and decrypt the data inside the standard SQL.
However, how do I read and write the data via an web application coded in C#.net and is also running on the same machine?
Another issue is, I need to replicate some of the data in this SQL standard over to a SQL mobile running on a mobile device running on Windows CE 5.0.
The mobile device also needs to read and write data to the encrypted data via a C#.net application.
Question is, with all these requirements to be met, can I use AES? I know that AES is not available on Windows XP and Windows Server 2000 and I cant find AES in the .net compact framework.
how do i go about ensuring security? how do I ensure that the symmetric key is the same both on the SQL standard and SQL mobile?
thank you.
I was wondering if anyone out there knows if it is possible to encrypt a particular field in a table, or encrypt a whole table. The info would remain on my database and not be sent out anywhere, but I just want an extra level of security against anyone who might try to break into the database.
