Security :: Encryption Algorithm - Encryption Of Data Required In The Coding?

Sep 16, 2010

Not sure if I'm posting the question in the right category.

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?

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?

Security :: Upgraded .Net From 1.1 To 2.0 - MD5 Encryption Is Different?

Mar 19, 2010

I inherited a ASP.Net website. Some changes need to be implemented. The login for the application is encrypted using the md5cryptoserviceprovider class. After upgrading to 2.0, the password is no longer encrypted the same as when it was 1.1.

I left the 1.1 virtual directory and it's still working. On the same box, I loaded the 2.0 code and setup a new virtual directory (which isn't encrypting the same as 1.1).

I copied the section below from the 1.1 machine.config section into the web.config and the 2.0 machine.config.

<machineKey validationKey="AutoGenerate,IsolateApps" decryptionKey="AutoGenerate,IsolateApps" validation="SHA1"/>

Here is the code that is generating the hash.

MD5CryptoServiceProvider encryptionServiceProvider = new MD5CryptoServiceProvider();

var bytes = ASCIIEncoding.ASCII.GetBytes(inputString);
