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.
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.
Is there a function that can encryp the data in a table(or certain column)? So if the table or column was query the person would see something like " !#)&%^#@ ". suggestion are welcome.
Is there a way to encrypt the data ( I mean actual data stored in a table)in a SQLServer. I know how to encrypt procedures, views, Net-libraries ......
How to get the encryption of certain characters, such as '12345' or 'hello'. Is any function to take regular characters and return the encryption form of those characters? Please help.
My client requested that the password field of a login table be encrypted using H5 Encryption. I've been searching throughout the net and MSDN for the function or procedure and can't find it. Does anybody know how?
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?
hi all, ive download some application, but they encrypt their Stored Proc and some Views.. 1.how to encrypt SP? 2.is it possible to decrypt whateva that encrypted?
Hai I am new to SQL server and working on Encryption.I just want to know whether it is better to encrpt a data in database or in the code itself.I want to encrypt a number and not a text.which one would u suggest RC4 algorithm or pwdencrypt..any one plz reply soon..
Hi, i was wondering if the whole table can be encrypted using MS SQL Server 2005. This at present can be done using third party softwares. Performance won't be an issue.
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')
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.
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?
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
i have to encrypt my data in sql2005 database using assymetric key encryption which i have done properly.But i have a doubt that while writing stored procedure i have to provide key information in it , that will be visible to everyone then whats the use of taht encryption. Can anyone tell me how can i write stored procedure without providing key information in it.
i am trying to encrypt my database using dbEncrypt software.The encryption provides role based access ot the database.In that case developer can not call any stored procedure of that database. These two are conflicting things. Can anyone suggest me a way so that i can access the stored procedure through my code by checking the roles from the front end. is it possible?? Please reply soon.
Hi all Im used to work on mysql and in that Db you can call the password function to encrypt password, so that people browsing directly the db can't see others password. What is the best way to do this in sqlserver ?
Does SQL Server 2005 not have a built in encryption function. I'm trying to INSERT and store passwords as an encrypted value in my table. Any help appreciated. Thanks.
I have created a DTS package on my SQL 7.0 SP3 server which simply reads a table on another SQL 7.0 server and populates a local table with the information that has been read.
Whenever I try to execute the DTS package (via Run or scheduling it) I get the following error:
------------------------------------------------------------------------- ... DTSRun: Executing... DTSRun OnStart: Delete from Table [AfterSalesAccessories].[dbo].[model_derivative] Step DTSRun OnError: Delete from Table [AfterSalesAccessories].[dbo].[model_derivative] Step, Error = -2147217887 (80040E21) Error string: The property 'Use Encryption for Data' is not supported. Error source: Microsoft Data Transformation Services (DTS) Package -------------------------------------------------------------------------
I have not selected the encryption option and can't see what I'm doing wrong. Has anybone else seen this ? I've looked on Technet but no joy.
Does anybody know how can I implement data encryption on the sql7.0 database? I need to do this with some of the fields, like credit card number. My sql server acts as backend database server for IIS servers.
Hi, In my SQL server 7.0, I have got 250 store procedures in each database. Before using them for my application, I want to ecyption all. I must add "WITH ENCRYPTION" string in each SP in all database and it'll take me a long time. Is there fastest way to encryption all SPs in all DBs? Have anyone got an utility SP ( or anyway else) to do this? Thanks in advance.
I am looking for a way to encrypt a column in my SQL Server Table. I have been looking in the books and have not found anything. Any ideas of how to do it?
I'm have set up sql 2000 in an active/passive cluster setup and I am looking to encrypt the data transfer from my backend DMZ (where the sql boxes reside) to the frontend dmz web servers.
I know there is a "check box" option but it says I need an encyption key to enrypted the data. From what I understand Certificate server 1.0 is not very good and the certificate services in Win2k requires ADS.
