Pass Phrase Encryption Question
Feb 9, 2008
I have a database that will be used by two or more organizations. I would like to use pass phrase encryption to encrypt a couple of columns.
I'm looking for suggestions on how I might set up the db to let the organization change the pass phrase that is used for their encryption?
I don't really want to hard code it into stored procedures or select statements with parameters. I will be using SSL if that should make a difference with what you suggest.
Any thoughts are appreciated.

A column in my database contains phrases such as "Extreme Golf: The Showdown" or "Welcome to Happy Land". I need to write a search engine so that users could type in phrases such as "Golf Extreme Showdown" or "Happy Land" and the correct, or closest matched results will be returned. I don't need variations of words, just phrase keyword match based search. I know I could do this by using multiple LIKE %% statements OR'd together, but this would be too performance intensive. So, I have heard I should use charindex somehow to achieve this in a stored procedeure. Does anyone have any clue how to solve this problem? Thanks!

Due to a business rule change, I had to take what was 1 column in a table and split it off into a new table. Now I need to find every time that column is used in a SPROC and change those sprocs. Is there a way to sift through the sprocs to search for a "phrase" (the column name) -- other than reading through every one manually?
Thanks

I have a repository with about 10,000 records. These records are selectable by searching by author surname, this works fine, but. the powers that be would like the data to be searchable by phrase. The db lives on a commercial host where I'm unable to create full text search catalogues.
I'd like to be able to return all results that contain both terms, or either if someone types in (for example) Breast Cancer. The search will only select from the the one field which will contain complex phrases such as "Second-line treatment of postmenopausal women with advanced breast carcinoma"
Any help on creating a select query that will do this will be greatly appreciated...

I have created two user defined functions for encryption and decryption using passphrase mechanism. When I call encryption function, each time I am getting the different values for the same input. While I searching a particular value, it takes long time to retrieve due to calling decryption function for each row.
best way to encrypt and decrypt using user defined functions.Below is the query which is taking long time.
SELECT ID FROM table WITH (NOLOCK)
WHERE dbo.DecodeFunction(column) = 'value'
When I try to use symetric or asymetric encryption, I am not able to put "OPEN SYMETRIC KEY" code in a function. So, I am using PassPhrase mechanism.

Hello all,
From what I've read, SQL Server is supposed to do a phrase match when you do a full text search that contains quoted literals. So, for example, if I did a full text search on the phrase "time out" and I put it in quotes, it's supposed to search for the full phrase "time out" and not just look for rows that contain the words "time" or "out." However, this isn't working for me.
Here is the query that I'm using :
SELECT *
FROM Content_Items ci
INNER JOIN FREETEXTTABLE(Content_Items, hed, '"time out"') AS ft ON ci.contentItemId = ft.[KEY]
ORDER BY ft.RANK DESC
What's it's doing is this : it's returning a bunch of rows that have the words "time" or "out" in the column called hed. It's also returning rows that have the full phrase "time out", but it's giving those rows the same rank as rows that only contain the word "time." In this case, that rank is 180.
Is there anything else I should be doing in my query, or is there some configuration option I should have turned on?
Thanks.

We compulsorily use NOLOCK in our scripts on reporting DB and development generally forget putting NOLOCKS or schema names with tables.
Creating a script to search for a missing word or a phrase in SQL Server script.
Our format is
<schema>.<table> <alias here> WITH NOLOCK <or alias here>
or
<schema>.<table> <alias here> NOLOCK <or alias here>
or
<schema>.<table> <alias here> (NOLOCK) <or alias here>
but generally developers write only <table> <alias>

I'm just wonder if this is a bug in MS Search or am I doing something wrong.
I have a query below
declare @search_clause varchar(255)
set @Search_Clause = ' "hepatitis b" and "hepatocellular carcinoma"'
select * from results
where contains(finding,@search_clause)
I don't get the correct result at all.
If I change my search_clause to "hepatitis" and "hepatocellular carcinoma -- without the "b"
then i get the correct result.
It seems MS Search doesn't like the phrase contain one letter or some sort or is it a know bug?
Anyone know?
Thanks

I was wondering if anyone out there knows if it is possible to encrypt a particular field in a table, or encrypt a whole table. The info would remain on my database and not be sent out anywhere, but I just want an extra level of security against anyone who might try to break into the database.

Hello,
I am needing to migrate an Access database to Sql Server
Express. This database will be distributed as part of a
VB 6 application. This database will have some of the
columns encrypted. My understanding is that SQL Server
Express supports encryption. We will need to be able to
run queries on encrypted data like this, with
LastName being an encrypted column in the database.
Select LastName from Account where LastName = 'Smith'
Select LastName from Account where LastName Like 'Sm%'
Update Account Set where LastName = sLastName
Can this be done using SQL Server 2005 Express and VB 6?
Thanks!

I am using server 2005 running on a windows server 2003 platform. I am trying to do field encryption using symmetric key implemented by the AES algorithm. I created an AES key and apparently it encrypts the data with no problem, however when I try to retrieve the data after decryption the field is always null. I tried using the same process while using the DES or RC2 algorithm and I could both encrypt and decrypt information, however it does not decrypt for any of the AES algorithm i.e. AES_128, AES_192 and AES_256. Attached is a simple query I used to test it.
create symmetric key CCardKeys
with algorithm = aes_192
encryption by password = 'P@s$w0rD'
open symmetric key CCardKeys
decryption by password = 'P@s$w0rD'
declare @Id varchar(50)
set @Id = encryptbykey(key_guid('CCardKeys'),'Test')
select convert(varchar(50),decryptbykey(@Id))
close symmetric key CCardKeys
Is there something I'm missing with AES.
Thanks for taking the time to help me.

Here is my goal please let me know if it is possible.
I have installed sql express on clients machines. I don't want them to be able to view the sp's or the functions. I would like to go as far as not allowing them to see the tables. I tried with encrption but this is still breakable by the user using the DAC.

I have a user table with Fields:
UID, name, SSN, phone,address. I need to encrypt all the fields except UID. My company recently moved to sql server 2005 and I have to encrypt old data. We do perform query search based on username and SSN
I have very shallow knowledge of encryption and indexes. I did looked at one of the articles on encrypting data on existing application but could not understand the indexing part(:()
Do i have to define new fields with varbinary as datatype(for ssn, name,phone number) ? I am asking this because in the demo only ssn_index has varbinary and the ssn field is still nvarchar?
Any help will be appreciated.
Thanks,
K

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
