Encrypt Connection With Certificate

Feb 7, 2007

I have been trying to create a certificate for use with SQL2005. I found openSSL to create a cert but I am not sure how to use it.

When I go into SQL Config Manager / Protocol Properties / Certificate Tab... I do not see any certificates. The list is empty. Where are these certs pulled from and how can I create one on my own?


Here are the Reqs:

Certificate Requirements

For SQL Server 2005 to load a SSL certificate, the certificate must meet the following conditions:

The certificate must be in either the local computer certificate store or the current user certificate store.

The current system time must be after the Valid from property of the certificate and before the Valid to property of the certificate.

The certificate must be meant for server authentication. This requires the Enhanced Key Usage property of the certificate to specify Server Authentication (1.3.6.1.5.5.7.3.1).

The certificate must be created by using the KeySpec option of AT_KEYEXCHANGE. Usually, the certificate's key usage property (KEY_USAGE) will also include key encipherment (CERT_KEY_ENCIPHERMENT_KEY_USAGE).

The Subject property of the certificate must indicate that the common name (CN) is the same as the host name or fully qualified domain name (FQDN) of the server computer. If SQL Server is running on a failover cluster, the common name must match the host name or FQDN of the virtual server and the certificates must be provisioned on all nodes in the failover cluster.

Certificate Loading Issue - When Creating Certificate From SQL Server To SQL Server Express On The Same Machine

Jun 29, 2007

Hi, We are trying to implement Service Broker between SQL Server Express and SQL Server on the Same machine and we are having problems with certificates. We are creating a certificate on SQL Server, backing up the certificate on a file system and then loading certificate on the SQL Server Express from the file and we are keep getting the following error: Msg 15208, Level 16, State 1, Line 1 The certificate, asymmetric key, or private key file does not exist or has invalid format.



Following script runs fine on SQL Server.




Code Snippet

use master



Create Master Key Encryption BY Password = '45Gme*3^&fwu';

BACKUP MASTER KEY TO FILE = 'C:ServiceBrokerPrivateKeyMasterB.pvk'

ENCRYPTION BY PASSWORD = '45Gme*3^&fwu'

Create Certificate EndPointCertificateC

WITH Subject = 'C.Server.Local',

START_DATE = '06/01/2006',

EXPIRY_DATE = '01/01/2008'

ACTIVE FOR BEGIN_DIALOG = ON;

BACKUP CERTIFICATE EndPointCertificateC

TO FILE = 'C:ServiceBrokerEndPointCertificateC.cer'



Following script runs on SQL Server Express:






Code Snippet

Create Certificate EndPointCertificateC

From FILE = 'C:ServiceBrokerEndPointCertificateC.cer'

WITH PRIVATE KEY (

FILE = 'C:ServiceBrokerPrivateKeyMasterB.pvk',

DECRYPTION BY PASSWORD = '45Gme*3^&fwu'

);





If we run the script other way around, it works fine. If we use the SQL Server on some other machine, the script works fine. But only on the same machine, it throws this error. We made sure the permissions and everything. Let us know if there is any work around or what are we doing wrong.



Any help is appreciated. Thank you,

Encryption With Certificate

Apr 19, 2007

 I am trying to create a encrypted row in my database Everything here worked except that when i run the final query to decrypt the data It just comes up with null for each row. Even if i do a query to show me the rows that are not null It's like it is saying yeah there is data here but I am only going to show you null instead of what I am supposed to decrypt.Here is what I tried from start to finish Create Certificate
TestCert
Encryption By Password = 'Password'
With Subject = 'SQLCert',
Expiry_Date = '12/01/2050';


declare @Test nvarchar(50)
set @Test='123456789'

insert into testenc (testencry)
Values
(encryptbyCert(Cert_ID('TestCert'),@Test ))


select convert (Nvarchar(50),
DecryptByCert(Cert_ID('TestCert'),
testencry,N'Password')) As Test
from testenc

Certificate Encryption

Apr 22, 2008

i'm totally stuck, i know i must be missing something, just can't find it.. here's my situation:

tbl_user (ssn char(9), ssn_encrypted varchar(9));

CREATE CERTIFICATE AUTOCERT WITH SUBJECT = 'Salad', EXPIRY_DATE = '1/1/2099';GO


UPDATE tbl_userset ssn_encrypted = encryptbycert(cert_id('AUTOCERT'),SSN)go

select ssn, ssn_encrypted from tbl_user

results look good. encryption worked.

SELECT ssn, decryptbycert(cert_id('AUTOCERT'),ssn_encrypted) FROM tbl_user

results of select statement show ssn_encrypted = null for every record.

why is it null? how can i get decryption to work?

he certificate cannot be dropped because one or more entities are either signed or encrypted using it.


Is there any way I can drop this as I would like to recreated it and add a whole host of sps that I need to use the xp_cmdshell.


Thanks in advance.

Certificate Not Yet Valid

Dec 22, 2006

Hi guys,



I'm having this really strange issue with mirroring.

I've followed the instructions on http://msdn2.microsoft.com/en-us/library/ms191140.aspx to the letter, leaving out the witness server part, as I don't have one.



All works OK, but when activating the mirroring on the principal server I get the usual error 1418 error. I fired up SQL Server Profiler to see what was happening, and the following error emerged.

Connection handshake failed. The certificate used by the peer is invalid due to the following reason: Certificate not yet valid. State 104.



Anyone have any ideas?

SQL Express SSL Certificate

Sep 30, 2006

Hello:

I am trying to get SQL Express to use a certificate for SSL encryption between the server and client. Our company has a certificate server and I already did generate a server certificate from it. I installed the certificate in the "local machine" store and I also have the CA certificate in the trusted root on the server machine. (XP PRO)

When I use the configuration tool, I get to the "protocols for SQLEXPRESS" area, I click properties, I select the certificate tab, but there are no certificates available from which to choose.

Can someone shed some light on where I might go from here?

3 Questions About Certificate

Nov 1, 2007

As we know ,certificate is a digitallly-signed security object that bind the public key to the principal who holds the private key.




Say i create a certificate by using create certificate DDL, then use it to encrypt data and decrypt data as follows:





Code Block
create certificate cert1 encryption by password='p@ssw0rd1' with subject='certificate test'
go
declare @plaintext varchar(100)
set @plaintext='abcd'
declare @cipher varbinary(8000)
set @cipher=encryptbycert(cert_id('cert1'),@plaintext)
select convert(varchar,decryptbycert(cert_id('cert1'),@cipher,N'p@ssw0rd1'))












Is that mean i create public key implicitly when i run "create certificate cert1 encryption by password='p@ssw0rd1' with subject='certificate test'"?

What cryptography algorithm would be use when i use the certificate to encrypt data ?
Where is private key? I ensure I use the public key which generated from "create certificate " DDL to encrypt data .I want to know which private key i used when i execute decryptbycert to decrypt.

Hello I haw trouble getting the service broker to work I have 3 instances of SQL servers:

What I wont is to be abele to do is to send a message from €śSender€? to €śReceiver 1€? or €śRecevier 2€?.

I am abele to send a message from €śSender€? to €śReceiver 1€? but if I send a message to €śReceiver 2€? I get a dialog security problem I think. If I use profiler I can se in €śReceiver 2€? the events:

Encrypt Function

Feb 16, 2003

Hi all

I have got an application developed on SQL7 which I have migrated to SQL2K.
It handles authentication internally and therefore stores usernames & passwords in a local table. The passwords are stored encrypted utilizing a function called "encrypt" taking the password in clear-text and returning a varbinary. When a user logs on his password input is encrypted the same way and compared to the stored password. So far so good...
Problem: On SQL2K the encrypt function returns a different result as it does on SQL7., which reults in authentication failures.
Unfortunately I cannot find any documentation about the encrypt function e.g. in BOL. Furthermore I cannot ask the developer who introduced the function anymore.

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

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?

I have SQL Server 2012 and want to encrypt my connections by using a wildcard [URL] ssl certificate from a trusted party. After installing my certificate i want to selecti in in de SQL Server Configuration Manager but the certificate does not appear in the properties of protocols.

In older versions it was possible to add the thumprint of my certificate to the registry, but in this version that result into a sql server that cannot be started anymore.

Certificate Private Key Cannot Be Found

Apr 15, 2014

I set up Service broker (2008R2 -> 2012) across different servers and domains using certificates.I set up 2 queues (one for sending, one for receiving).I set up 6 services (3 for send, 3 for receive), all 3 sharing the same queue type. (srv_send_1, srv_send_2, srv_send_3), (srv_receive_1, srv_receive_2, srv_receive_3).I set up a route for each receiving service on the source, and for each sending service on the target.I set up a SB binding to the remote for each sender service type.I granted send rights to the sending services on the source server.

I then tested my first service, and it worked perfectly (still works).My second service however is failing with the error "The certificate's private key cannot be found".I am stumped, as all the setup code was a lot of copy/paste which I have checked, rechecked and even re-coded.Basically, here is what Im doing:

begin dialog @ConversationHandle
FROM Service srv_send_1
TO Service 'srv_receive_1'
ON CONTRACT myContract
WITH ENCRYPTION = OFF, LIFETIME = 60*60*24*7;
SEND ON CONVERSATION @conversationHandle
MESSAGE TYPE [my_msgtype] (@xml);

The above code works 100% with service1, but not with service2.Note that on profiler, the target server doesnt receive any communication. The error shows on the sender profiler.Also, The conversation shows up as CONVERSING in sys.conversation_endpoints and the entry exists in sys.transmission_queue.

SQL 2012 :: Certificate And Password Changes

Oct 29, 2015

We are in the process of deploying security software that will change AD service accounts automatically every 90 days. I was wondering if changing the password on accounts used for SSRS certificates will break the certs? Are there any other gotchas we should be concerned about with automated password changes in SQL?
