I'm writing a php program and I would like to know how I could encrypt only the connection string (if that€™s possible) to connect to a database (SQL Server 2005 Express Edition).
Web Server -----> connection string (Ciphertext) -----> SQL Server 2005
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 All, In SQL 2000, i need to Export Data,so that datashould be encrypted.When i try to import that in any database it should authenticate the user and should get decrypted.IZAT Possible.
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.
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
Hi, 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
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?
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?
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!!
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.
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.
hi, in my login form i have the password field.so i am sending password to my database table but while sending password has to be encrypted and while returning it has to be decrypted,is it possible to do in database if means please show me some example please
I need to store payroll information (pay rates) in my data warehouse.I've search on field level encryption and most the stuff i find is forpasswords, I.E. not reversable. I need to protect the payrate fieldfrom dba's and sa's, but I need to allow the authorized users to seethe contents.Any ideas? Does 2005 handle this?I don't have a web app, per se, that access's this information. howeverI am using Cognos' Report Net.thanks in advanceRob
1. How to encrypt data of database in SQL Server 2000 ? Someone can't see true data
if without password or something else.
2. If i have 2 database . All of them have same table, structure, ....How to update or insert or change in the second database when i update or insert or change in the first database automatically ?
I want to encrypt certain data like password, ssn, credit card info etc before saving in database. Also, this encrypted data can be queried using standard SQL statements like:
select * from users where userid=454 and password = 'encrypted data'
The mechanism to encrypt data could be in a .net application. The code that does encryption/decryption should also be protected so that it doesnt work if it falls in wrong hands.
Can anyone suggest what would be the best way to accomplish above?
