SQL Server Admin 2014 :: Cannot Decrypt Encrypted Columns From Database Backup On Local Machine

Jun 29, 2015

I've a SQL server 2014 running on one of our server. We're in the process of implementing security steps for our databases. I've encrypted a column in one of the table in the database on the server. The issue is when I restore the backup on my local SQL server and run a query to decrypt the column data it gives me null values. On the other end when I decrypt the column data on the main server it works fine. I found a thread on this forum which states to do the following when restoring the encrypted database on different server.

USE [master];
GO
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'StrongPassword';
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY;
GO

select File_Name
, CONVERT(nvarchar,DECRYPTBYKEY(File_Name))
from [test].[dbo].[Orders_Customer]

I tried doing above still no luck.

Hi,





In BI Tool SSIS Packages run fine and get data From Oracle and Save it in SQL Server.

Package Protection Level is EncryptSensitivewithPassword.

In BI tool when i open the package it ask password and then run fine.

Copy Database With Encrypted Column To New Server And Decrypt Column There

Aug 17, 2006

To do this successfully do I need to backup the Service master, Database master, and database itself from the the Source server, then restore all three of them on the destination server?

(I'm concerned that restoring the source Service Master key to a new target server with an existing sql 2005 install will screw things up big time.)

TIA,

Decrypting And Encrypted Stored Procedure

Sep 6, 2007

Hello,
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,
?????

Problem Restoring Database With Encrypted Columns To Different Database Or Server With Encrypted Columns.

Jan 23, 2006

I 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.

Encrypt On CLR Decrypt In SQL?

Jan 8, 2008



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

Encrypt In .net, Decrypt In Sql

Feb 29, 2008

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?

Is There Any Way To Decrypt The Login Info?

May 19, 2006

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.

Db_datareaders Can Decrypt Data?

Jan 19, 2007

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.

Users For Encrypt And Decrypt Purposes Only

Jan 13, 2006

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

Failed To Decrypt Protected XML Node

Jun 27, 2007

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!
