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?
I just finished reading an article on how to search encrypted data efficiently and they suggested creating a new column with a Message Auhtentication Code. To be honest, reading the aritcle makes my head hurt. I can hardly understand what they were doing myself and I can't begin to explain it to a developer.
Are there any easier ways to search encrypted columns for a speciifc match? If not, does any have some stored procs that implement this messy MAC stuff?
I am using a sql server 2012 and having a database "Test".In this database , having a table "Employee". I have encrypted the employe table data with the password. How can is use these employee data in oracle server. ie;How can I show the employee data as the encrypted and decrypted form of data in Oracle server( The actual encryption happened only in SQL DB).
I've been searching for information on this for awhile unsuccessully. I am using SQL Server 2005 Enterprise Edititon and transactional replication with separate publisher, distributor and subscribers. I need to encrypt data on our publisher and then I need to replicate that data out (i.e., encrypted data, not encrypted transmission). Since the keys are server specific, I imaging there might be some difficulty in doing this, but I figure I can't be the only one with this problem. Does anyone have a resource or know what must be done to get this accomplished?
I have two databases, one production and other a production copy.
One column of the production table is encrypted by the following syntax.
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password!'
CREATE CERTIFICATE cert_demo
WITH SUBJECT = 'encryption demo'
CREATE SYMMETRIC KEY symkey_demo
WITH ALGORITHM = TRIPLE_DES
ENCRYPTION BY CERTIFICATE cert_demo
-----------------------------------
I have stored procedure to add records to a production table like this.
ALTER Procedure AddRecord
@id int,
@var1 varchar(100)
AS
BEGIN
DECLARE @var2 varbinary(256)
OPEN SYMMETRIC KEY symkey_demo
DECRYPTION BY CERTIFICATE cert_demo
SET @var2 = EncryptByKey(
key_guid( 'symkey_demo' ),
@var1 )
insert into dbo.Test(id,Data,EData)
values(@id,@var1,@var2)
CLOSE SYMMETRIC KEY symkey_demo
END
---------------------------------
Now I need to decript the data in the production copy database. So I had export production data to the production copy database and also generates the same key and cerificate. When i tried to decrypt the data, no results has returned.
Create procedure ViewData
@id int
AS
BEGIN
DECLARE @var1 varbinary(256)
DECLARE @var2 varchar(100)
OPEN SYMMETRIC KEY symkey_demo
DECRYPTION BY CERTIFICATE cert_demo
select @var1=EData from Test where id=@id
Set @var2 = convert( varchar(100), DecryptByKey( @var1))
print @var2
END
It doesn't print the enctypted data. Please suggest what goes wrong.
I got a problem concerning encryption. The thing is I have decided to use symmetric key protected by certificate to encrypt certain information. Certificates are protected by database masterkey and by service key.
But I also want to be sure that if someone steals my database with all its data he wont be able to decrypt it with his own SQL Server Management Studio where he has all the permissions.
Also after some time I will need to take my database and set it up on another PC.
Has anyone ideas how to solve this??
P.S. As far as I know if symmetric key is protected by certificate which is protected by DB master key and service master key then you cant decrypt data if database is moved to another workstation and opened with another Management Studio. Please can anyone explain how this works( if its true). And if this is true then how can i move my DB without loosing access to encrypted data???
I am new to database programming and was curious how others solve theproblem of storing encrypted in data in db table columns and thensubsequently searching for these records.The particular problem that I am facing is in dealing with (privacy)critical information like credit-card #s and SSNs or business criticalinformation like sales opportunity size or revenue in the database. Therequirement is that this data be stored encrypted (and not in theclear). Just limiting access to tables with this data isn't sufficient.Does any database provide native facilities to store specific columns asencrypted data ? The other option I have is to use something like RC4 toencrypt the data before storing them in the database.However, the subsequent problem is how do I search/sort on these columns? Its not a big deal if I have a few hundred records; I couldpotentially retrieve all the records, decrypt the specific fields andthen do in process searches/sorts. But what happens when I have (say) amillion records - I really don't want to suck in all that data and workon it but instead use the native db search/sort capabilities.Any suggestions and past experiences would be greatly appreciated.much thanks,~s
I have read recommendations about searching encrypted data. Typically, they involve creating a MAC (message authentication code) table. One of the elements of that table is a HASH of the encrypted data (plus a Mac key) that is used as an index for searching. Is that HASH as secure as the encrypted data itself, or is this approach less secure? If it is less secure, then may I assume that approach is the only feasible way to search data encrypted by nondeterministic algorithms?
Hi, I have database with encrypted column data in my customer server. Sometime, I might need to backup their database back to office for troubleshooting.
How could I backup/restore master key, symmetric and asymmetric key created for my database?
I am using SQL Server 2008 R2.I have opened the Reporting Service Configuration Manager to delete the encrypted data.In the encryption key section, when I click on the 'Delete' button to delete the encrypted data, it gives me below error.

I want to retrieve SQL 2000 Encrypted Column Data From SQL 2005 strored proc. My Stored Procedure was on SQL 2000 and it works fine....Then I restore Database From SQL 2000 to SQL 2005. The Following Statement is on my store proce.
select user_id , Encrypt(user_pass) from OpenRowset('SQLOLEDB','myserver';'sa';'mypass',databasename.dbo.users) as a
The Following Error I get When I execute the above statement.
Msg 195, Level 15, State 10, Line 1
'Encrypt' is not a recognized built-in function name.
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
I'm very new new at this. I'm try to deploy a report model and got this message. I have no idea what its going on about.
Can anyone help me?

when we built the login control by built in login control of vs2005 the passwords are saved in the database which is automatically created.how can i get the unencrypted form of these passwords from database.
Hi 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??
I wonder if it is possible to retrieve encrypted password somehow? Like I have saved password (blueRays) in encrypted formate. How can I retrieve it "where password='blueRays' "?
In 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
Can anyone tell me how to find out if a .sdf file is encrypted? Im using C# and would like to know if the db that I am trying to open is encrypted. I would then like to attempt to open the db.
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?
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?
I have some encrypted stored procedure. I want to use the output of the encrypted stored procedure insert the output into temp table. is it possible to do. If so please let me know how can I proceed. Thanks in advance
I 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?
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?
I Forgot for my longtime used home expense update application password which has backend sql expressedition database.
