Encrypted Tables
Apr 28, 2000Hi there,
I was wondering if anyone knew of a way to encrypt a table?
I now you can encrypt Stored Procedures, triggers and view, but
can you encrypt a table??
Let me know
Thanks

Joing 2 Tables On An Encrypted Column
Mar 18, 2008Hi all,
I am trying to join 2 tables in my database on an encrypted column. I am using a symmetric encryption, but because of the IV, a string encrypted at 2 different times produces 2 different encrypted strings. Therefore, I can not merely join the 2 tables on the encrypted columns. Has anyone any insight on techniques for solving this problem? The most naïve way, would be to decrypt both tables, join them, and re-encrypt them again. But, the tables are quite large, and this would be very processor (and time) intensive.
Any help would be greatly appreciated. Thanks in advance for any suggestions.
SQL Server 2008 :: Script Out Tables With Encrypted Triggers?
May 14, 2015I am trying to run a test migration of our application from V8 to V9. To do this I am creating an empty database by running the Tasks -> Script database
Once that is done, I restore it to our dev server and run SQLCompare against it to generate the change scripts
The problem I am facing is that there are a few tables that have encrypted triggers on them and I cannot include them in the generate scripts. I want to take the table structure, including indexes, but I am not interested in the triggers. There are only 5 tables so I could script them by hand, but this means that I cannot automate the process.
As a result of the missing tables SQLCompare will try to generate a CREATE TABLE rather than an ALTER TABLE DDL
The live migration won't be a problem because this will be a database restore and migration - my problem is the CREATE TABLE DDLs in the script.
Problem Restoring Database With Encrypted Columns To Different Database Or Server With Encrypted Columns.
Jan 23, 2006I need to start encrypting several fields in a database and have been doing some testing with a test database first. I've run into problems when attempting to restore the database on either the same server (but different database) or to a separate server.
First, here's how i created the symmetric key and encrypted data in the original database:
create master key
encryption by password = 'testAppleA3';
create certificate test
with subject = 'test certificate',
EXPIRY_DATE = '1/1/2010';
create symmetric key sk_Test
with algorithm = triple_des
encryption by certificate test;
open symmetric key sk_Test decryption by certificate test;
insert into employees values (101,'Jane Doe',encryptbykey(key_guid('sk_Test'),'$200000'));
insert into employees values(102,'Bob Jones',encryptbykey(key_guid('sk_Test'),'$500000'));
select * from employees
--delete from employees
select id,name,cast(decryptbykey(salary) as varchar(10)) as salary from employees
close all symmetric keys
Next I backup up this test database and restore it to a new database on a different server (same issue if restore to different database but on same server).
Then if i attempt to open the key in the new database and decrypt:
open symmetric key sk_Test decryption by certificate test;
I get the error: An error occurred during decryption.
Ok, well not unexpected, so reading the forums, i try doing the below first in the new database:
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY
Then I try opening the key again and get the error again:
An error occurred during decryption.
So then it occurs to me, maybe i need to drop and recreate it so i do
drop symmetric key sk_test
then
create symmetric key sk_Test
with algorithm = triple_des
encryption by certificate test;
and then try to open it.
Same error!
So then i decide, let's drop everything, the master key, the certificate and then symmetric key:
drop symmetric key sk_test
drop certificate test
drop master key
Then recreate the master key:
create master key
encryption by password = 'testAppleA3';
Restore the certificate from a backup i had made to a file:
CREATE CERTIFICATE test
FROM FILE = 'c:storedcertsencryptiontestcert'
Recreate the symmetric key again:
create symmetric key sk_Test
with algorithm = triple_des
encryption by certificate test;
And now open the key only to get the error:
Cannot decrypt or encrypt using the specified certificate, either because it has no private key or because the password provided for the private key is incorrect.
So what am I doing wrong here? In this scenario I would appear to have lost all access to decrypt the data in the database despite restoring from a backup which restored the symmetric key and certificate and i obviously know the password for the master key.
I also tried running the command
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY
again but this does not resolve the issue.
Thx.

View 2 Replies View RelatedIs Data Sent Via DTS Encrypted?
Jan 27, 2005Hi all,
I may have a requirement to send data from a SQL Server at site A to an Oracle server at site B. These sites have no network connection between them, and the current suggestion is to use ftp, but the transfer (or username and password) will not be encrypted.
If I create a DTS package transferring data from site A, will that transfer be encrypted?
If not, is there an option with SQL Server DTS to ensure that the data is sent in an encrypted form?
Thanks in advance.

DTSRun Encrypted
Jul 20, 2005In a Multi Server Job under SQL Server Agent (MSX), we have a series ofsteps like:DTSRun /~Z0x8E8635E6BBA...The ~Z means it's an encrypted hexidecimal string. The person who createdthis step is no longer accessible, and the string can't be triviallydecrypted, so I don't know what this runs.Someone once mentioned that I could go to Query Analyzer, run it, andwatch the execution plan. However, if I start the job, the executionplan simply walks through the steps required to find the job, and doesn'tgo into the details of the job. I don't know how to run the DTSRuncommand directly within Query Analyzer.Is there a way I can use the execution plan to determine what package thisDTSRun line is executing? Please give me the appropriate command orcommands.-Adam

How Are Endpoints Encrypted?
Dec 13, 2007Hi All,
I have mirroring set up in a test environment and it works great however I need to know/understand how the endpoints are encrypted. I have them set to use the AES algorithm; however I can not tell from BOL what keys they are using. I know the service master key is the root encryption key and endpoints sit at the server level (same level as service masterkey) but I am not sure if the endpoints use it to perform the encryption or not; do they and if not what do they use?
Thanks in advance,

Store Encrypted Passwords In SQL
Jan 14, 2005Hello,
I have a simple .NET page that asks the user to create a new account. One of the fields on that page is 'Password'. I store the password in a SQL 2000 Database. However, it appears in the database as clear-text.
Is there a way to encrypt this so it doesn't appear as clear-text in the DB?
Thanks!

Save Encrypted Password
Feb 6, 2003I have a USERS table on an SQL Server 2000 with two fields, USER_NAME AND PASSWORD, and I want to encrypt the passwords when I stored them on the table.
I used {Encrypt N ‘MyPassWord’} to encrypt the password and it looks that the passwords have been encrypted.
Went, however, I execute a SELECT statement for a specific password all passwords are returned.
This is a small sable code:
------------------------------------------------------------------------------------------------
CREATE TABLE dbo.Users
(
User_Name nvarchar (10) NOT NULL ,
PassWord nvarchar (50) NOT NULL
)
GO
INSERT INTO USERS (User_Name, PassWord)
VALUES ('MyName', {Encrypt N 'MyPassWord'})
GO
INSERT INTO USERS (User_Name, PassWord)
VALUES ('YourName', {Encrypt N 'YourPassWord'})
GO
SELECT * FROM USERS
WHERE PassWord = {Encrypt N 'MyPassWord'}
(2 row(s) affected)
-------------------------------------------------------------------------------------------------
Unfortunately both (All) rows are return
Is it any way to encrypt password and be able to select them?
Is it any other way to encrypt data into the database?
Thank You

View 7 Replies View RelatedEncrypted Stored Procs
Sep 7, 2007Hey yall
I ran into something interesting today and was wondering how one would do this. I have some 3rd party stored procs and one was kicking out a truncate error so I took it upon myself to investigate the stored proc that was kicking out this error. So when I tried viewing the sp, I received an error:*****Encrypted object is not transferable, and script could not be generated.***** and then it brings up a blank editing screen.
First I believe this was a custom error message as it just doesnt seem like the way SQL Server would have presented it.
So how would someone prohibit viewing of a stored proc like this?
Thanks

Prefix On Encrypted Columns
Apr 26, 2007I read a previous post that Raul responded to on the format of the data prefixing Symmetric key encrypted columns, is it possible to reproduce these from a client? Given I know the key name, i can pull back the first 16 for the GUID, for now 01000000 will work for the version, the IV can be created or read, but the last 8 bytes were marked as 'header', can I get an explanation on what this is or if it is required?
The purpose is in being able to do SQL Server compatible encryption on the client side, given a shared certificate for the public password. I certainly can do this with a CLR function and use my own encryption, but comparably it is dog slow, the built in SQL functions will encrypt/decrypt 100k rows in about 20 seconds or less on my test box, where as the CLR function takes 5.5 minutes. This performance difference is too huge to ignore.
I would like to be able to generate a SQL Server compatible prefix for a Symmetric keyed column or find a way to improve the CLR function performance of an AES_256 (rijndael) up to something at least remotely close to the built in functions.
Any help would be appreciated.

Encrypted DB -- Restore Question
Dec 28, 2005Hi,
I have a DB in which I encrypt a few columns in a table. I am using a Symmetric key to encrypt and decrypt the data. When I take a back up of this DB and restore on another server ... my decryption doesn't work. I have dropped the master key and recreated it with same password and that didn't help either.
What are the rules to follow when we restore a db on a different server that has encrypted data ?? Thanks.
Getting: The Key Is Not Encrypted Using The Specified Decryptor After DB Restore.
Jul 11, 2007We are using SQL Server 2005
A client of ours did a back up and restore of a database which we have created a db master key as well as asymmetric, symmetric keys and certificates.
After the restore we issue:
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'ourpwd'
go
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY
go
We get the following error:
Msg 15313, Level 16, State 1, Line 1
The key is not encrypted using the specified decryptor.
Msg 15581, Level 16, State 3, Line 2
Please create a master key in the database or open the master key in the session before performing this operation.
I had the client issue the Open Master Key statement in the prod DB and got the same MSG 15313 error. But, the encryption functions still work on their DB.
I am not able to reproduce the errors in house on our own DB's.
What does the error:
Msg 15313, Level 16, State 1, Line 1
The key is not encrypted using the specified decryptor.
Indicate?
Have they been using the wrong password to try to open the key?
I have been searching all morning and can not find any good documentation regarding the error.
Thanks in advance for any help.

Encrypted Password In DB And Reused Later

I thouth to encrypt password with hash + salt method.
The problem....
Hashing password means that they are not decrypted ...only compared ..and here the problem....I would like to reuse this password to be used in the addlinked server store proc and other sql statement.
How can I Manage encrypted password to be used later...
thank for any suggestion....
How To Identify A Dialog As Encrypted?

How can I distinguish between the one requested with no ecryption and requested with encryption but setup with none due to the lack of a key?
SSL Encrypted ODBC Connection
Dec 7, 2006I have a question regarding the configuration of SSL for SQL Server connections. I am very familiar with configuring IIS to use SSL certs and the host headers that are different from the physical machine name however I do not see these same provisions in SQL server.
I.E.
I have a server on a domain named MYDB and the domain is mydomain.dom and I have an external domain name on the internet as a whole that has a domain name of externaldomain.com can I get a SSL cert that has the common name as db.externaldomain.com or do I have to set the common name to mydb.mydomain.dom. I just did not see a place where I can tell SQL server to use that cert like you would in IIS. I am also assuming that if I get this cert from a major vendor like thawte, verisign etc I won't have to setup any kind of trust on the client side since these are already trusted correct? I want to SSL secure an odbc connection that will be going over the general internet so I would prefer not to use a self-signed cert.
Thanks in advance for any help

Copying Encrypted Objects ?

Filter By Encrypted Field Value
May 17, 2006
I have a table which includes an encrypted field. In the following statement...
select cast(decryptBykey(Column2)as varchar(max)) as column2new, column1 from testtable where cast(decryptBykey(Column2) as varchar(max))=@p1
I retrieve the (now decrypted) secure column as well as another column and then filter the results by a parameter on the (now decrypted) secure field.
Furthermore, if I wanted to sort on the encrypted field, I would once again have to call the cast(decryptbykey... function. It seems to me that this kind of statement would perform poorly since I have to call the same function numerous times. Is there a way to call this function once and then reference the resultant field value throughout the rest of the statement?
I assume that this situation is the same if I call any SQL function to alter a field value..not just the decryptbykey function
Thanks,

Apr 20, 2005Hi everyone,
I am currently reading ASP.NET unleashed and practising few examples. The following code converts a user's text into a symmetric encryption:
'nd: define keys
Const DESKey As String = "ABCDEFGH"
Const DESIV As String = "HGFEDCBA"
'nd: convert string to byte array

arrChar = strInput.ToCharArray
Dim arrByte(arrChar.Length - 1) As Byte
For intCounter = 0 To arrByte.Length - 1
arrByte(intCounter) = Convert.ToByte(arrChar(intCounter))
Next
Return arrByte
End Function
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
Dim arrDESKey As Byte()

objCryptoStream.Write(arrInput, 0, arrInput.Length)
objCryptoStream.Close()
lblDone.Text = "Done!"
End Sub
It works fine. But, how to i save this encrypted password into a database field instead of a writing it to a file? Also, could some please tell me how to paste code into this forum? I tried <code></code> tags but it did not work.
