I have to Encrypt and Decrypt Back the Password field in sql server i have used the pwdencrypt and pwdCompare() but i dont have to compare but i have to display the password back using the Decrypt technique Is there any algorithm which i can use only for encryption and decryption of password field?
View 4 RepliesI have a table called 'products'. In each table there is a column named 'description' of type ntext (sql server 2000). The description conains a ton of text and within that text there is an ip address many times.

1) I'm working in a project where encryption of data is high priority. Could some one suggest what would be the best encryption method to protect data from being cracked.
I'm using TCP/IP protocol.
2) Is HTTPS totally secured. If I'm using HTTPS, does that mean that there is no encryption of data required in the coding?
i need to implement a standard encryption decryption logic across an entire project platform which has different clients implemented using different platforms as follows:
iphone app (objectiv c)
website (classic asp)
webservice (asp.net)
samsung bada app (c++)
the iphone app as well as the website need to send info to webservice using encrypted query strings
the web service then decrypts this and processes the info further
wanted to know the simplest way to achieve this. is there some free and ready to use binary available with an easy to use api to achieve this?
encryption needs to be as secure as possible
edited: currently we use AES on the website and webservice front

View 1 RepliesThis is meant to be easy ...so ive been told, but still cant get it to work!I have a sql database hosted on a shared server which requires the use of sql authentication.As a result I require to encrypt my sensitive data in the config (connection strings etc).I understand that you can do this using aspnet_regiis etc, but ive been told that as I have no direct acccess to the server, I may need to program the encryption.
I have seen a few examples, but as a novice I have been banging away at this, looking at an errors screen most of the time!
We are designing a .net web application that has an external and internal site.
Both sites need to encrypt data only the internal site needs to decrypt data.
We are wondering what are the best practices for:

View 1 RepliesI have a page that will receive an encrypted query string containing a user name, password & jobId, the problem is I don't want someone to be able to grab the encrypted url (browser history) and reuse it, so it has to change each time the page is requested.
The only way I can think of doing this is by having an encryption key associated with the the job and then change it after each time the page is requested. The client would either request the key or the entire url from a web service residing on my server.
Is this the best way to do this?

View 1 RepliesFor our website, we have decided we would like to maintain our user passwords as encrypted binary data in our database. We are using ASP.NET 3.5 to host our site and SQL Server Express 2008 for the database, both running on the same server. When a user logs in and submits a username and password, there will need to be some sort of encryption or decryption in order to verify the credentials. To me, it would appear that there are 3 ways to do this:
1)[C# Encyrption] On User creation, perform encryption in the Web App and submit the encrypted password to the database. To verify credentials at Login, perform the same encryption on the submitted password and ensure that it matches the value stored in the database.
2)[SQL Encryption] On User creation, submit the plain-text password to the database and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, have the database perform decryption on the password during the SELECT statement, and compare the plain-text submitted password to the one in the database.
3)[Mix] On User creation, submit the plain-text password to the database, and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, perform the same encryption algorithm used by SQL on the submitted password ( is this possible? ), and ensure that it matches the value stored in the database.
Does anybody have an opinion as to which of these options is best? Number 1) is the most familiar to me, and would be the easiest to use with LINQ to SQL ( which is our current data model ), so I am leaning towards that. But if there are better options I would love to know about them.

View 4 RepliesUnable to read local eventlog (reason: The data area passed to a system call is too small). This error is recorded in the event log every minute in the production server, and because of this the SQL Server 2000 performance is very slow and the box is also working slow. This indirectly affects my application and productivity.
