Using Symmetric Key Problem With Encryption, Decryption Works Fine
May 4, 2006
Hey I had a table with a column of data encrypted in a format. I was able to decrypt it and then encrypt it using Symmetric keys and then updating the table column with the data. Now, there is a user sp which needs to encrypt the password for the new user and put it in the table. I'm not being able to make it work. I have this so far. Something somewhere is wrong. I dont know where. Please help Thanks. I used the same script to do the encryption initially but that was for the whole column. I need to see the encrypted version of the @inTargetPassword variable. But it's not working. It doesn't give me an error but gives me wrong data...
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) Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 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.
This function is used to initialize the seed for the RC4 algorithmCREATE FUNCTION dbo.fnInitRc4 ( @Pwd VARCHAR(256) ) RETURNS @Box TABLE (i TINYINT, v TINYINT) AS
BEGIN DECLARE@Key TABLE (i TINYINT, v TINYINT)
DECLARE@Index SMALLINT, @PwdLen TINYINT
SELECT@Index = 0, @PwdLen = LEN(@Pwd)
WHILE @Index <= 255 BEGIN INSERT@Key ( i, v ) VALUES( @Index, ASCII(SUBSTRING(@Pwd, @Index % @PwdLen + 1, 1)) )
INSERT@Box ( i, v ) VALUES( @Index, @Index )
SELECT@Index = @Index + 1 END
DECLARE@t TINYINT, @b SMALLINT
SELECT@Index = 0, @b = 0
WHILE @Index <= 255 BEGIN SELECT@b = (@b + b.v + k.v) % 256 FROM@Box AS b INNER JOIN@Key AS k ON k.i = b.i WHEREb.i = @Index
SELECT@t = v FROM@Box WHEREi = @Index
UPDATEb1 SETb1.v = (SELECT b2.v FROM @Box b2 WHERE b2.i = @b) FROM@Box b1 WHEREb1.i = @Index
UPDATE@Box SETv = @t WHEREi = @b
SELECT@Index = @Index + 1 END
RETURN ENDANd this function does the encrypt/decrypt partCREATE FUNCTION dbo.fnEncDecRc4 ( @Pwd VARCHAR(256), @Text VARCHAR(8000) ) RETURNSVARCHAR(8000) AS
BEGIN DECLARE@Box TABLE (i TINYINT, v TINYINT)
INSERT@Box ( i, v ) SELECTi, v FROMdbo.fnInitRc4(@Pwd)
Hi, Does any body have a stored procedure or a function I can use? What I need is to encrypt and decrypt a password using Tiny Encryption Algorithm, SO I have an encryption scalar valued function or sproc and similarly decryption function or sproc.Now I need rolling keys to encrypt and decrypt, so I have a table which has keys used for encryption and decryption and depending on the dtae the keys are different.So I alos need a sproc to retrieve the keys.If anybody has done it before or can point me to where can I go let me know?
Database Security, we are going to use AES 256 Symmetric Encryption. We will be using RSA for Asymmetric Key Encryption, 1024 Bits.
We got the code working for the seond case but for the first, WHEN:
CREATE SYMMETRIC KEY sym_Key WITH ALGORITHM = AES_256 ENCRYPTION BY ASYMMETRIC KEY asym_Key GO
THEN:
-- Msg 15314, Level 16, State 1, Line 1 -- Either no algorithm has been specified or the bitlength and the algorithm specified for the key are not available in this installation of Windows.
What can be the way out to be able to create the AES 256 Symmetric key.
Hi - this is a repost of a question that I originally posted in Security. Ok, I'm very new to this topic. I'm working on an application that requires that some information in the db be encrypted and then decrypted when retrieved. I have everything set up and it works fine except for one thing. I can't seem to be able to pass a parameter into the sp that is used to decrypt the key. It only seems to take the string when typed in. I really think I'm missing something here. It doesn't seem all that great to have your password hard-coded into the stored procedure. Maybe I'm just screwing something up? Anyway, I can't get it to work if it looks like this:OPEN SYMMETRIC KEY Key_NameDECRYPTION BY PASSWORD = @pwdThis does work:OPEN SYMMETRIC KEY Key_NameDECRYPTION BY PASSWORD = 'password'This has to be some goof on my part right? If the db machine is compromised you're giving the keys to decrypt the data away as well - they just haver to open your stored proc. You should keep them separate imo and I hope someone can set me straight. Also, encrypting the stored procedure is an option, but it's very easy to decrypt from what I've read. Can someone help point me in the right direction? Thanks! And thanks to the mod that suggested moving this post. Any help will be appreciated.
I am planning to use XP_CRYPT for encrypting and decrypting cc#'s, passwords etc., at database level. Any suggestions or experiences on this. More info about this product at http://www.activecrypt.com/faq.htm
I am working to set up encryption of my database. am trying to implement a process proposed by the DoD Standard Technical Implementation Guide (STIG) and cannot figure it out. I am using SQL 2012 and the requirement is to
A: Run the following to create a certificate: USE <'database name'> CREATE CERTIFICATE <'certificate name'> ENCRYPTION BY PASSWORD = '<'password'>' FROM FILE = <'path/file_name'> WITH SUBJECT = 'name of person creating key', EXPIRY_DATE = '<'expiration date: yyyymmdd'>'
This script did not work – I did not know what file it was referencing and it kept erroring out, so I used my own process as follows
USE master GO CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'mY_P@$$w0rd' CREATE CERTIFICATE certificate_name WITH SUBJECT = 'Certificate for my database'
[code]....
This also error out, but my questions are the following:
-What would the symmetric key be encrypting? -The application that is using the database is IIS, so would there be a problem with it communicating with the database? -Does the key need to be installed on that IIS server? -Do I need to apply the encryption to the database, column or table.
Hi. I have a SQL Server 2000 database that contains information I would like to encrypt. The information is a field inside a table, and I would like to encrypt this information using a key, and decrypt it in my asp.net application using that key and use the decrypted data. Please tell me how this can be done, or direct me to an article or a link on the subject. Thanks in advance.
i've getting ready to implement encryption on a rather large database. I'd read that if performance is of utmost concert, you should use symmetric keys. I want to encrypt those keys by asymmetric keys. My code is working, but i'm just not sure if there is a quicker way? do you have to open and close the key each time you select/update/insert in a stored procedure that references an encrypted column, or is there a way to just modify the code by adding the encryptbykey/decryptbykey functions?
has anyone implemented encryption on columns in large tables? any suggestions for me?
Thanks, Pete
here's my code to create the keys:
create asymmetric key ASK_Auto_Encrypt with algorithm = RSA_512;
create symmetric key SK_AE with algorithm = TRIPLE_DES encryption by asymmetric key ASK_Auto_Encrypt;
here's my code to test this:
create table encryption_test (test varchar(50));
open symmetric key SK_AE decryption by asymmetric key ASK_Auto_Encrypt;
insert into encryption_test select encryptbykey(key_guid('SK_AE'),'test');
select convert(varchar(max),decryptbykey(test)) from encryption_test;
Please be gentle...I am very new to working with SQL.
I have the need to encrypt my columns in SQL 2005. I have created a symmetric key 'SecureKey' as well as a secure certificate 'SecureCert'
I have ran the script to create the key and the certificate successfully. When I run "select * sys.symmetic_keys;" the key shows up...when I run "select * sys.certificates;" the cert shows up.
Here is my issue, in the security folder under my database, these two things do not show up in the appropriate folders. Also when I run my encryption scripts, I am getting an error of
"msg 15151, Level 16, State 1, Line 3
cannot find the symmetric key 'SecureKey', because it does not exist or you do not have permission"
We have been playing around with encryption in 2005. I cannot find a BOL topic that discusses dropping encryption objects such as keys.
We do the followign steps:
Create master key with password, then we create a certificate using the master key, we then create a symmetric key using this certificate and encrypt data columns.
But what i find worrying is that you can then drop the symmetric key , there are no warnings that you have objects dependant on this key for decryption.
Once you have dropped the key you cannot decrypt the data anymore?
Also the key defults the expiration date to 1 year.
WHat happens after 1 year when you have encrypted data and an expired key, or someone drops the key ? How can you ever decrypt the data after that ?
You can backup master keys nd certificates but not symmetric keys?
It seems to be that youc an very easily orphan encrypted data by the loss of the symmetric key for whatever reason, is this correct ?
I have a question about the storage of symmetric keys in SQL Server 2005 due to the fact that I have read two conflicting statements on this.
In Laurentiu's blog located at http://blogs.msdn.com/lcris/archive/2005/10/14/481434.aspx, in regards to preventing symmetric key loss he makes the statement that "...Because the keys are stored in the database, they will be saved with the database....".
But in the white paper Improving Data Security by Using SQL Server 2005, which is located at http://www.microsoft.com/technet/itshowcase/content/sqldatsec.mspx, in regards to symmetric keys the statement is made "...Note: The symmetric key is not stored in the database. Only the encrypted values of the symmetric key are stored in the database. Therefore, users who can access the database cannot decrypt the data without first decrypting the symmetric key....".
So I am just wondering which statement is correct, are symmetric keys stored in the database or not?
I created stored function with encryption. after i created i dont able to view the source code from system tables or any tool. i have get back the original source code
note: i want to stored function not for stored procedure.
I would like to be able to store user network passwords in a database table and be able to encrypt and decrypt using stored procs. Could anyone give me a pointer on this.
I have created mirroring... one of the column is encrypted on mirror database and I can see the decrypted result when I do query when I actually logged into server (through remote connection) but when I use the same query through using SSMS from my laptop the query result come as the column is not decrypted,
I currently have a login page in asp.net 2.0 linked to a SQL 2005 database table that holds the usernames and passwords. At present, I am on an "honor system" where I do have access to the passwords of the other users but would like to change it so that I cannot know what the users' passwords are. Thank goodness that there is no personal information within the pages and the logins were created to keep a log of who logs in and what not. However, I would like to soon hold more personlized information, hence the need to encrypt each user's password even from myself. I have read up on Symmetric Encryption for SQL 2005 but I would like to know if there is anything else available, any good proven methods that someone else has already tried. Also, while testing out Symmetric Encryption, I noticed that I have to supply the encryption password for the decryption. However, if I know what the password for the encryption/decription is, does it not defeat the purpose of having the encryption at all, in terms of the "Admin" having access to sensitive information? Just curious if I understood the concept correctly or not. Thanks in advance to all.
I am trying to implement the column encryption on one of the tables, have used the below link as the reference and got stuck at the last step.
[URL] ....
I have completed the following steps so far.
- CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘myStrongPassword’
- CREATE CERTIFICATE MyCertificateName WITH SUBJECT = 'A label for this certificate'
- CREATE SYMMETRIC KEY MySymmetricKeyName WITH IDENTITY_VALUE = 'a fairly secure name', ALGORITHM = AES_256,
[Code] .....
Example by using the function
EXEC OpenKeys
-- Encrypting SELECT Encrypt(myColumn) FROM myTable
-- Decrypting SELECT Decrypt(myColumn) FROM myTable
When I ran the last command :
-- Decrypting SELECT Decrypt(myColumn) FROM myTable
I get the following error :
Msg 257, Level 16, State 3, Line 2 Implicit conversion from data type nvarchar to varbinary is not allowed. Use the CONVERT function to run this query.
Where will I use the convert function, in decrypt function or in select statement?
I am stuck at a very awkward place. I have created one package which uses an oracle view as its source for data transfer the problem is when i run the package through dtexec it works fine but when i try to schedule it I get the following error

I am able to run the package outside the sql job and also connect to the oracle. I have oracle 9i client installed on the server and sql server is 2005.
I have many jobs on sql 05 and all work but one. This one writes to an Access DB on the same server as SQL. The package works fine. But when executed in the context of the SQL Agent job, it fails.
Jobs that write to a text file work fine. The Access DB has no password required. By the way, that job in sql 2000 worked fine.

If this post belongs somewhere else I appologize. I have spent several days trying to solve this problem with no luck. My site is online. Hosted at NeikoHosting. I can connect to the database remotely when adding a datacontrol. It tests fine. But when running the page it won't connect. Even if I go in and change the Web.Config connection string to a local Data Source provided to me by Neiko, it still won't work. It just won't connect. Here are the two connection strings in the Web.Config, minus my login info: Only the remote string will pass testing. Neither works on the site. <add name="yourchurchmychurchDBConnectionString" connectionString="Data Source=MSSQL2K-A;Initial Catalog=yourchurchmychurchDB;Persist Security Info=True;User ID=me;Password=pwd" providerName="System.Data.SqlClient" /> <add name="yourchurchmychurchDBConnectionString2" connectionString="Data Source=66.103.238.206;Initial Catalog=yourchurchmychurchDB;Persist Security Info=True;User ID=me;Password=pwd" providerName="System.Data.SqlClient" /> Here is the stack trace, if that helps.

I have the following query which works fine when it's executed as a single query. but when i union the result of this query with other queries, it returns a different set of data.
any one know why that might be the case??
select top 100 max(contact._id) "_id", max(old_trans.date) "callback_date", 7 "priority", max(old_trans.date) "recency", count(*) "frequency" --contact._id, contact.callback_date from topcat.class_contact contact inner join topcat.MMTRANS$ old_trans on contact.phone_num = old_trans.phone where contact.phone_num is not null and contact.status = 'New Contact' group by contact._id order by "recency" desc, "frequency" desc
i've included the union query here for completeness of the question

I have a report which I have tested and works fine. now I'm trying to use it as a subreport. the "outer" or main report is very simple: it just has a company standard banner and some header/footer information, and then a single subreport. there is no passing of parameters between main report and sub report. the subreport does have its own parameter to govern its dataset, and provides its own default for that.
The error that I'm getting is this:

Of course, this doesn't happen when I execute the subreport by itself. What kinds of things should I be looking at to get to the bottom of this. Thanks!
We have one LEDGER, where all the daily activities are stored. The LEDGER table has 4 indexes (1 clustered and 3 non-clustered). To get AR we use this table.
Well problem is some times in 1-2 months, any simple AR query takes a long time and every other client gets slow response (queries are very slow or sometimes block).
If we DROP any index on LEDGER table and again put it back (RECREATE), all our queries work fine and faster. This goes on till 1-2 months, till we see the same issue again.
This is a classic case happened today. Queries were running fine till morning 8 AM. We upload some 50 thousand records to Ledger table (Data Conversion). Well after 30 mins, all simple AR queries started taking a long time. We DROPPED an index in LEDGER table and everything was faster....Just to be same we added back the same index again.......everything is Faster.....
What is this. ....is it our QUERY, index or huge Transactions or no free space ???
We are scheduled to run SP4, next week. But is there any solution in the mean time on what is this?
Also is they any way to KILL all SQL server processes that take more than a mins. We just don't want ALL our client to Slow down because of one query????
People,I'm trying to publish my first website and am having a few problems.I've got Visual Web Developer 2005 Express and am trying to use the Personal Website Starter Kit. (my SQL server is SQL Server Express Edition 2005 - which is also running on my local machine)It seems to work fine when I run it on my localhost, as soon as I ftp it up to my web hosting company, I get an error message (see below) :-An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) My hypothesis is :-It would appear to me that when running locally, the starter kit website uses my installation of SQL 2005 Express Edition, but when I upload all the files, I'm guessing the application is still trying to point at a local instance of SQL on my local PC which it now cannot see. I'm guessing I need to somehow upload the SQL database onto my web host (I've purchased 100M of SQL Server 2005 space), and point the application at that SQL instance instead. But I don't know if I'm right about all this, or indeed how to do it if I am. Can anyone help?Much thanks in advance,Will

I have a simple update statement that is running forever in SQL 2005 but works fine in SQL 2000. We have a new server we put SQL 2005, restored db. The table in question WEEKLYSALESHISTORY I even re-indexed all the indexes and rebuilt the stats as well. But still no luck, still running extremely long. 1 hour 20 minutes.
I'll try to give you some background on these table. Weeklysalehistory has approx 30 fields. I have 11 indesxes set up weekending date being one of them. And replication control has index on lasttrandatetime as well. So I think my indexes are fine.
/* Update WeekEnding Date for current weeks WeeklySales Records */ Update WeeklySalesHistory set weekendingdate = (SELECT LastTransDateTime from ReplicationControl where TableName = 'WEEKHST') where weekendingdate is null
Weekly sales has approx 100,000,000 rows Replication control has 631,000 (Ithink I can delete some from here to bring it down to 100 or 200 records) Although I don't think this is issue since on 2000 has same thing and works fine.
I was trying to do this within SSIS and thought that was issue. I am new so SSIS but it runs long even if I just run it as a job with this simple Update statement so I think its something with tables, etc that is wrong.
One thing on noticed if I look at the statistics in SQL Server Management studio there is a ton of stats. some being statistics on indexes which makes sense then I have a ton of hind_113_9_6 and simiiar one like this. I must have 90 or so named like this. Not sure how to check on SQL 2000 all the stats to see if they moved over from there or what. I checked a few other tables and don't have all these extra stats. Could this be causing the issue do I need to delete all these extras? Any help would be greatly appreciated.
