How To Encrypt Views?

Hi,
I found that I could encrypt StoredProcedures in Sql Server Express but have no idea about encrypting views. Any idea?
Hi,

Fellow database developers,I would like to draw on your experience with views. I have a databasethat includes many views. Sometimes, views contains other views, andthose views in turn may contain views. In fact, I have some views inmy database that are a product of nested views of up to 6 levels deep!The reason we did this was.1. Object-oriented in nature. Makes it easy to work with them.2. Changing an underlying view (adding new fields, removing etc),automatically the higher up views inherit this new information. Thismake maintenance very easy.3. These nested views are only ever used for the reporting side of ourapplication, not for the day-to-day database use by the application.We use Crystal Reports and Crystal is smart enough (can't believe Ijust said that about Crystal) to only pull back the fields that arebeing accessed by the report. In other words, Crystal will issue aSelect field1, field2, field3 from ReportingView Where .... eventhough "ReportingView" contains a long list of fields.Problems I can see.1. Parent views generally use "Select * From childview". This meansthat we have to execute a "sp_refreshview" command against all viewswhenever child views are altered.2. Parent views return a lot of information that isn't necessarilyused.3. Makes it harder to track down exactly where the information iscoming from. You have to drill right through to the child view to seethe raw table joins etc.Does anyone have any comments on this database design? I would love tohear your opinions and tales from the trenches.Best regards,Rod.

Newbie here. I've only been using SQL for about a year now and have some minor questions about sql objects that reference other objects.
We have some views which reference other views in the joins. I will call one the primary view and the one being referenced in the joins as the secondary view.
Recently we made changes to the secondary view.
After which the primary views which referenced it would not work because of this change and had to be 'refreshed' by using drop/create scripts which essentially just dropped it and recreated the exact same view. I do not recall the exact error message that was returned other than it seemed to suggest that it could no longer see the secondary view since it had been changed. Nothing in the primary view was changed in any way, just the secondary.
Some here where I work have suggested off hand that this was a recompile of the primary view because the contents of the secondary changed.
My questions are:
1. Exactly why did this happen and is there a proper name for it when it does?
2. The same problem does not seem to occur when we have stored procedures referencing views in the joins which had just been changed. Why is that?
Thanks for any help on the matter. I greatly appreciate it.
Hello,
to make a report easier I'm developing it using a view of joined views of joined views.
Is there any significant performance penalty as opposed to just having one big select?
Cheers.
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.
Hi Guys.
I am looking for TSQL code for RC4 encryption and decryption.
I found VBcode for RC4 encryption, it will take atleast 2 days for me to go thru that and rewrite the whole code in SQL.
If anyone has the code, please provide me.
(I know sql does accept extended ASCII characters)
Thanks

Hello,
I do have one application in VC++ as a Front End & Sql Server 2005 as a Back End.
i want to store my username's password in encrypted format, means no one can able to see the password.
Ex:- if i enter password as a "xyz" then it should be save as a some encrypted [base 64 encoding scheme] format.
Can any one help me out?
Thanks

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

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?

Hi,I have a .net application and i added a code that encrypts data saved in database. However, there is already data in the fields that was entered before this change.I know need to check if the values in those fields are encrypted and if not i need to encrypt them.How can I perform such a check and update the relevant data?I use TrippleDES in .net to encrypt/decrypt the data.Thanks

I would like to know that how can I encrypt a stored procedure, so that it can not be decrypt by me or not by any one ? I have tried using the SQL encrypt,but there is a decrypt command which decrypt the same. I do not want any one to decrypt without a password or encrypt the stored procedure so that it can never be decrypted.
Thanking you,
Regards..Jay
Hi,
Please help!!!!!!!
Is there are ways to encrypt data in the table (SQL Server 7) and then retrieve (decrypt) this information?
Thanks
I'm running SQL 70 SP 3 on Nt4.
We store passwords of users of our website. They need to be autenticated and based on that it gives them access to what they are entitled. But its not like NT or server authentication.
This has been setup so that we have a user table and it stores the password. However, it stores it in plain text. Is there any way I can encrypt this field so it is unreadable? Is there a property or a datatype that I can't find? Is there a way to simulate the encryption?
Any ideas or help are appreciated.
Thanks

I am setting up several isql job in Enterprise Manager and as a cmdexec job I need to pass the user id and password( -P). I shtere any way not to pass this as text and perhaps hide/encrypt it since any one who opens the task scheduler and looks at the job can read the password?
Thanks.

Does SQL Server 2000 provide any data encryption/decryption functionality so that certain fields (e.g. SSN, Age and Salary) will be encrypted before writing into the table and decrypted once loading out of the table?

We like to secure datas.
Only a few people are autorized to read this information, but today, these informations are readable with a simple query with a query analyzer for exemple.
I'd like to encrypt datas with reversible function in one field of a table
Is there a function able to do this kind of work in SQLServer V7 or 2000 ?
hello guys! i have a question hope you'll help me..how can i encrypt the data that is stored in my password field everytime i insert value to it and decrypt it if i want to retrieve it? thanks in advance!!
View 7 Replies View Relatedhi guyz!! is it posible to ecnrypt data everytime i insert it to a table and decrypt it everytime I select it using the MS SQL 2005 alone?
like for example i have this query statement below
insert username,password users values ('daimous','my_password')
what i want is every time i insert a value to the password column that value should be encrypted first.
select username,password from users
everytime i select the value of the password column should decrypted.
Thanks in advance!!!
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.
How might I encrypt a stored procedure in SQL server.
In sybase this is done with SP_HIDETEXT but SQL server doesn't appear to have this.
Is there another way?
Thanks,
Any t-sql query that will encrypt several databases without using the use DB_name? I am trying to create a SP that will look for the flag if 0 then encrypt.
SELECT name AS 'Database_Name' ,
is_encrypted AS 'Encryption Enabled'
FROM sys.databases
where database_id not in (1,2,3,4)
and is_encrypted = 0
However I cannot find a query that will set encryption on with having to use the USE DB_NAME clause.

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
