Hi Laurentiu
I was reading a blog entry of yours http://blogs.msdn.com/lcris/archive/2005/10/14/481434.aspx and in the section "How to prevent a symmetric key loss", you mentioned key_source.
I am trying to understand how this is used because when you open a symmetric key, the only options for decrypting the key are password, symmetric key, asymmetric key and certificate.
Thanks

Msg:
Invalid use of side-effecting or time-dependent operator in 'OPEN SYMMETRIC KEY' within a function.
"open symmetric keys" is not allowed in a function?
if I want to encrypt a string in a function by sql2005's internal functions ,how can I do ?
Say i have some symmetric keys encrypted by other symmetric keys ,
is there some way to find the relationship of these key?
I know i can find the certificate or asymmetric key through sys.key_encryptions catalog view by "thumbprint" column,
but the thumbprint column is null when the key was encrypted by a symmetric key.
any suggestions?
thanks in advance
Respectd sir
thanks for your reply but my issue is different.
In my database have lots of table, In each table have different datatype field.
we want to just encrypt these data.
As example i am declare one table
TableCD
---------
CDID Integer Not Null
VolID Integer NotNull
CDRegDate DateTime
CDData1 BigInt
CDAmtInWord Varchar(100) not null
Data Is
CDID VolID CDRegDate CDData1 CDAmtInWord
1201/10/2008102014521 cr.
1302/10/2008102014531 cr.
our requirement is just encrypt this data with symmetric key and decyrpt this data.
Please immediate reply me.
Thanks

how to create rdl using stored procedure which uses parameter
Thank you.
I create a script like below:

According to the option selected, I should have the query look like:
1."Less than Jan 1 2007"
select * from table_name
where open_date < Jan 1 2007
or
2."Greater than Jan 1 2007"
select * from table_name

Please let me know how can I acheive this.I'm Using ORACLE database
Hi,
I'm working on custom report manager. It manages "report entities" and
"report templates" (actually, RDLs uploaded on the server) and stores
one-to-many relation between them. The task is to store
"MasterEntityID" report parameter in every RDL and keep it up in actual
state whether RDL is being assigned to another entity or new RDL is
being uploaded and assigned. I've covered the first issue with
SetReportParameters() web method, but how should I deal with the second
one? Uploaded RDL may be short of the param, so I have to add it
programmatically while uploading.
Thanks,

Hi - this is a repost of a question that I originally posted in Security. Ok, I'm very new to this topic. I'm working on an application that
requires that some information in the db be encrypted and then
decrypted when retrieved. I have everything set up and it works fine
except for one thing. I can't seem to be able to pass a parameter into
the sp that is used to decrypt the key. It only seems to take the
string when typed in. I really think I'm missing something here. It
doesn't seem all that great to have your password hard-coded into the
stored procedure. Maybe I'm just screwing something up? Anyway, I
can't get it to work if it looks like this:OPEN SYMMETRIC KEY Key_NameDECRYPTION BY PASSWORD = @pwdThis does work:OPEN SYMMETRIC KEY Key_NameDECRYPTION BY PASSWORD = 'password'This
has to be some goof on my part right? If the db machine is compromised
you're giving the keys to decrypt the data away as well - they just
haver to open your stored proc. You should keep them separate imo and
I hope someone can set me straight. Also, encrypting the stored
procedure is an option, but it's very easy to decrypt from what I've
read. Can someone help point me in the right direction? Thanks! And thanks to the mod that suggested moving this post. Any help will be appreciated.
I am working to set up encryption of my database. am trying to implement a process proposed by the DoD Standard Technical Implementation Guide (STIG) and cannot figure it out. I am using SQL 2012 and the requirement is to
A: Run the following to create a certificate:
USE <'database name'>
CREATE CERTIFICATE <'certificate name'>
ENCRYPTION BY PASSWORD = '<'password'>'
FROM FILE = <'path/file_name'>
WITH SUBJECT = 'name of person creating key',
EXPIRY_DATE = '<'expiration date: yyyymmdd'>'
This script did not work – I did not know what file it was referencing and it kept erroring out, so I used my own process as follows
USE master
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'mY_P@$$w0rd'
CREATE CERTIFICATE certificate_name
WITH SUBJECT = 'Certificate for my database'
[code]....
This also error out, but my questions are the following:
-What would the symmetric key be encrypting?
-The application that is using the database is IIS, so would there be a problem with it communicating with the database?
-Does the key need to be installed on that IIS server?
-Do I need to apply the encryption to the database, column or table.
Hi
I am using sql server 2005, I want to encrypt data and i am using Symmetric key.
In Symmetric key encrypt the varchar , varbinary data encrypt but for integer it show the error.
so please suggest me can we encrypt the integer data.
if yes then how ?
In below example if we use integer then encrypt it will show error.
--1) Create master key.
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'Asit'
--2) Create certificate.
CREATE CERTIFICATE CertificateTest2
WITH SUBJECT ='CertificateTest2'
--3) Create SYMMETRIC KEY .
CREATE SYMMETRIC KEY TestSymKey
WITH ALGORITHM = TRIPLE_DES
ENCRYPTION BY CERTIFICATE CertificateTest2
--4) Open SYMMETRIC KEY .
OPEN SYMMETRIC KEY TestSymKey
DECRYPTION BY CERTIFICATE CertificateTest2;
--5) create table.
create table SYMMETRIC1
(
id varchar(100) not null primary key ,
name varbinary(MAX) not null,
card_num varbinary(MAX) not null
);
--6)SEA THE RECORDS
SELECT * FROM SYMMETRIC1
--7)INSERT RECORD IN TABLE
INSERT INTO SYMMETRIC1(ID,NAME,CARD_NUM)VALUES (
EncryptByKey( key_guid('TestSymKey'),'2',1,'SQL Server') ,
EncryptByKey( key_guid('TestSymKey'),'Asit sinha',1,'SQL Server'),
EncryptByKey( key_guid('TestSymKey'),'11',1,'SQL Server') )
--8)FETCH ENCRYPTED RECORD FROM TABLE AND DECRYPT THE VALUE
SELECT
convert(varchar(max),DecryptByKey(id,1,'SQL Server')) as ID,
convert(varchar(max),DecryptByKey(Name,1,'SQL Server')) as Name,
convert(varchar(max),DecryptByKey(card_num,1,'SQL Server')) as Card_Num
FROM SYMMETRIC1
--9)SEA THE RECORDS
SELECT * FROM SYMMETRIC1

Hi,
I want to create a symmetric key that will be encrypted by certificate key. Can u guide me which algorithm is best out of the following:
DES, TRIPLE_DES, RC2, RC4, RC4_128, DESX, AES_128, AES_192, AES_256.
I tried using AES_128, AES_192, AES_256 but it says 'the algorithm specified for the key are not available in this installation of Windows.'
Pls tell me which else algorithm is best to use and pls specify why.
Thanks

I have symmetric key named "PasswordKey" in a database in a default instance. The key works correctly in the default instance. However, I have a report server in an instance named "sqlexpress" that also needs to decrypt a column using the same key. I get an error that states: Cannot find the symmetric key 'PasswordKey', because it does not exist or you do not have permission.
What permission does the symmetric key need? Someone suggested granting permission to the database role but what role in the named instance needs permission?
grant references on symmetric key :: PasswordKey to user
Who is the user if the report server is in an instance named sqlexpress?

I'm trying to develop a procedure for re-encrypting data with a different symmetric key, but I need the new key to use the old key name. I want to do this without leaving the data in clear text at any point. I would think the process would work like this:
1.Create a new key
2.Decrypt data w/old key and encrypt with new key.
3.Drop old key.
4.Rename new key using the old key name.
However, I can't find that there's a way to rename a symmetric key. Is this correct? If that is the case, I believe I have to do an additional round of encryption:
1.Create a temp key
2.Decrypt data w/old key and encrypt with temp key.
3.Drop old key.
4.Create a new key with the old key name.
5.Decrypt data w/temp key and encrypt with new key.
6.Drop temp key
Thanks for any insight.
In the below sproc I want to create a view based on the incoming parameter, which is a date passed on from VB in the format 01-01-2006.
Yet getting that to work, seems quite a challenge.
I've been dabbling a bit with the sproc and QA, passing the date parameter to it in varous forms, using both single, double and triple quotationmarks and changing the parameter type to datetime.
I either wind up with a syntax error " Incorrect syntax near '01' " or " Unclosed quotation mark before the character string ".
Anyone have a guess at how to fix this issue?

i've getting ready to implement encryption on a rather large database. I'd read that if performance is of utmost concert, you should use symmetric keys. I want to encrypt those keys by asymmetric keys. My code is working, but i'm just not sure if there is a quicker way? do you have to open and close the key each time you select/update/insert in a stored procedure that references an encrypted column, or is there a way to just modify the code by adding the encryptbykey/decryptbykey functions?
has anyone implemented encryption on columns in large tables? any suggestions for me?
Thanks,
Pete
here's my code to create the keys:
create asymmetric key ASK_Auto_Encrypt
with algorithm = RSA_512;
create symmetric key SK_AE
with algorithm = TRIPLE_DES
encryption by asymmetric key ASK_Auto_Encrypt;
here's my code to test this:
create table encryption_test (test varchar(50));
open symmetric key SK_AE
decryption by asymmetric key ASK_Auto_Encrypt;
insert into encryption_test
select encryptbykey(key_guid('SK_AE'),'test');
select convert(varchar(max),decryptbykey(test)) from encryption_test;
close symmetric key SK_AE;
Please be gentle...I am very new to working with SQL.
I have the need to encrypt my columns in SQL 2005. I have created a symmetric key 'SecureKey' as well as a secure certificate 'SecureCert'
I have ran the script to create the key and the certificate successfully. When I run "select * sys.symmetic_keys;" the key shows up...when I run "select * sys.certificates;" the cert shows up.
Here is my issue, in the security folder under my database, these two things do not show up in the appropriate folders. Also when I run my encryption scripts, I am getting an error of
"msg 15151, Level 16, State 1, Line 3
cannot find the symmetric key 'SecureKey', because it does not exist or you do not have permission"
Am I missing something?

I'm having some issues restoring a backup of database that uses native encryption onto another server. I know there are a couple of articles on this but I seem to be missing something. Any help would be greatly appreciated.
Current Server Windows 2000
Destination Server Windows 2003
The original key setup for the current server was achieved by something like this:
CREATE SYMMETRIC KEY HR01 WITH algorithm=DES encryption BY password = 'HRpassword'
Running the command select * from sys.symmetric_keys on the current server I get the following:
name
principal_id
symmetric_key_id
key_length
key_algorithm
algorithm_desc
create_date
modify_date
key_guid

So I restored the database onto the new server and ran this script:
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'Password';
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY;
GO
I don't have a master key... so I go back to the original server and ran this script and did another backup:
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'Password'
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'Password';
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY;
Running select * from sys.symmetric_keys on the current server now looks like this:

I then restored the new backup onto the 2003 server and ran this script:

ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY;
GO
The alter script now runs fine but I get the error message: The decryption key is incorrect when trying to open the HR01 key
I've played with various configurations of the MS SQL Server encryption functionality, and come across an embarrassingly easy question that I cannot seem to resolve. How do I retrieve the actual symmetric and asymmetric keys out of the database?
I'd like to explore the possibility of off-loading the encryption/decryption work from the database server to a load-balanced pool of servers. For this model to work the pool would need access to the keys. The symmetric keys currently are generated with the command...
create symmetric key EncryptionKey211
with algorithm = AES_256
ENCRYPTION BY certificate CreditCardCert
Am I missing something obvious here?
Is there a limit on number of symmetric keys/asymmetric keys/certificates that can be stored in a database?
Is there any effect on performance of the SQL Server if I have too many (few hundreds) symmetric keys in the database?
thanks
I create a certificate and a symmetric key encryption by it.
Then i create a user and grant the view definition permission of both object to the user.
But it return a error message "Cannot find the certificate 'cert1', because it does not exist or you do not have permission" when execute the open symmetric sql statement as the user.
It' very surprised that it return a string when execute encryptbyCert function ,but it return null when execute decryptbyCert function...

Hi There
We have been playing around with encryption in 2005. I cannot find a BOL topic that discusses dropping encryption objects such as keys.
We do the followign steps:
Create master key with password, then we create a certificate using the master key, we then create a symmetric key using this certificate and encrypt data columns.
But what i find worrying is that you can then drop the symmetric key , there are no warnings that you have objects dependant on this key for decryption.
Once you have dropped the key you cannot decrypt the data anymore?
Also the key defults the expiration date to 1 year.
WHat happens after 1 year when you have encrypted data and an expired key, or someone drops the key ? How can you ever decrypt the data after that ?
You can backup master keys nd certificates but not symmetric keys?
It seems to be that youc an very easily orphan encrypted data by the loss of the symmetric key for whatever reason, is this correct ?
Thanx
I have a question about the storage of symmetric keys in SQL Server 2005 due to the fact that I have read two conflicting statements on this.
In Laurentiu's blog located at http://blogs.msdn.com/lcris/archive/2005/10/14/481434.aspx, in regards to preventing symmetric key loss he makes the statement that "...Because the keys are stored in the database, they will be saved with the database....".
But in the white paper Improving Data Security by Using SQL Server 2005, which is located at http://www.microsoft.com/technet/itshowcase/content/sqldatsec.mspx, in regards to symmetric keys the statement is made "...Note: The symmetric key is not stored in the database. Only the encrypted values of the symmetric key are stored in the database. Therefore, users who can access the database cannot decrypt the data without first decrypting the symmetric key....".
So I am just wondering which statement is correct, are symmetric keys stored in the database or not?
Thanks!

Hello. I have a problem that spans VB.net, SQL Server and SSIS but is rooted in the need to encrypt column data in SQL Server.
I would like to encrypt data that I am bringing into SQL Server in the Data transformation script component of an SSIS package. I have achieved this but I can't decrypt the data because the keys don't match. I would like to use symmetric key encryption but I don't see how to get the symmetric key that I created in SQL Server available to the VB.net script component in SSIS.
Please advise me if my approach is correct and what steps I need to take.
I can't seem to use symmetric keys in stored procedures. I am trying to decrypt a column in my stored precedure but the values are all NULL. First I tried a symmetric key that required a password but I kept getting simple syntax errors when I tried to send the password to the stored precedure as a parameter. Now I am trying a symmetric key that uses a certificate.
I also tried using WITH EXECUTE AS SELF and WITH EXECUTE AS CALLER but that made no difference.
