View State Encryption


Hi All,

Why is it that I see the same hash value generated when I use different algorithms for viewstate encryption. I have added below lines to the web.config file

Cryptography: Employ Strong Encryption in Your Apps with Our CryptoUtility Component


When storing sensitive data, you need to be able to identify threats, determine how these threats interact with each other, and how issues can combine to constitute a vulnerability that will leave your data exposed. With a good understanding of the various cryptographic algorithms, salt, hashes, ACLs, and other available techniques, you'll be in a better position to protect your critical data.

.NET Remoting: Secure Your .NET Remoting Traffic by Writing an Asymmetric Encryption Channel Sink


As .NET Remoting gains popularity in the enterprise space, it must meet business demands for trustworthy computing. Remoting traffic can be secured when objects are hosted in IIS, but when they aren't hosted in IIS, custom security solutions can be developed to secure them. This article provides an in-depth look at writing channel sinks for .NET. It also details the flow of data through custom channel sinks and explains the kinds of manipulations that can be performed on that data.

Symmetric Key Encryption on the Compact Framework

There are two main types of encryption algorithms available within the .NET Compact Framework - symmetric and asymmetric encryption. This blog entry will discuss how to utilise symmetric key encryption, but first we have to outline the difference between Symmetric and Asymmetric encryption (I will discuss asymmetric key encryption in a future blog entry).

Symmetric and Asymmetric Key Encryption
Symmetric encryption algorithms (also known as ciphers) process plain text with a secret encryption key to create encrypted data (called cipher text). The same secret key is used to decrypt the cipher text back to plain text.

Asymmetric encryption (also known as public-key encryption) is a cryptography technique that uses public and private key pairs to encrypt and decrypt data respectably. The private key is a closely guarded secret, while the public key can be freely distributed over untrusted networks. You do not worry who has your public key (you could print it on a 100foot tall banner if you so desired), but you must keep your private key secret.

Encryption/Decryption OAEP

I have some code: string newKey = AmazonFeedBrowser.Security.CryptoKeyContainer.GetKeyFromContainer("KeyContainer", true); RSACryptoServiceProvider trsa = new RSACryptoServiceProvider(); trsa.FromXmlString(newKey); string tu = Convert.ToBase64String(trsa.Encrypt(Encoding.UTF8.GetBytes("Administrator"), true)); Debug.WriteLine(tu); newKey = AmazonFeedBrowser.Security.CryptoKeyContainer.GetKeyFromContainer("KeyContainer", false); trsa = new RSACryptoServiceProvider(); trsa.FromXmlString(newKey); Debug.WriteLine(Encoding.UTF8.GetString(trsa.Decrypt(Convert.FromBase64String(tu), true))); I get a cryptographic exception indicating that the OAEP padding cannot be processed. The RSACryptoServiceProvider (trsa) is initialized with just the public key. It seems to work OK with the public and private key. Is there a way to use OAEP with just the public key? Error occurred while decoding OAEP padding. System.Security.Cryptography.CryptographicException was unhandled Message=Error occurred while decoding OAEP padding.

SQL Server Compact 3.5 Encryption Questions

If I create a database (.sdf file) on a server and set it to be encrypted, should it be able to be opened on a device or other PC?  In other words, is there anything in the encryption that is machine specific?  Or is it really that the password is what lets me connect and the encryption prevents it from being read by some other tool like a hex file viewer as one post suggested. I've read through lots of posts and documentation and I'm just trying to understand how encryption works and if there are any limitations or considerations and haven't found a good source. Thanks

Coldfusion AES encryption

Hi all, I saw another post on the subject but it was for a different type of encryption. Anyway, we have some values that are stored in our database using the Coldfusion ecrypt() function. We are using AES and Hex. it looks like this: <cfset Variables.THE_VALUE_ENCRYPTED = Encrypt("#ARGUMENTS.THE_VALUE#","#Variables.ENCRYPT_KEY#","AES","Hex")> The key is 24 bit.  For the life of us, we can't find any way to decrypt this in .net. Can someone offer some guidance? IT would be greatly appreciated.

SQL Server 2008 R2 Express + Wildcard Certificates

Note: Cross-posted from my question at ServerFault: http://serverfault.com/questions/176595/sql-server-2008-r2-express-wildcard-ssl-certificate (Not trying to be a jerk, just think I might get a better response here.) --- Wildcard certificates (for example, *.example.com) simply did not work in SQL Server 2008 or lower. But Encrypting Connections to SQL Server on MSDN states, plain as day, that SQL Server 2008 R2 supports wildcards certificates. Excellent. So I set up SQL Server 2008 R2 Express on a machine, and I configure the HKLM\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer\SuperSocketNetLib\Certificate entry to the thumbprint of my wildcard SSL certificate (because in five years of dealing with SQL server, I have never gotten that #$@# dialog in Sql Server Configuration to display any certificates). The SQL Server log then tells me that this went over quite well: 2010-08-31 11:46:04.04 Server The certificate [Cert Hash(sha1) "5DDD9E51B30E0CA6CE3656AE54EC6D0B8B75904A"] was successfully loaded for encryption. Unfortunately, if I attempt to use Microsoft SQL Server Management Studio (the 2008 R2 version) or the Sql* classes provided in the .NET Framework 4.0, I always receive the following exception: A connection was successfully established with the server, but then an error occurred during the pre-login handshake.

Why SQL accepts both encrypted connection and non-encrypted connections when force encryption option

I have installed a certificate and have set force encryption to yes under the flags' tab of protocols' window as well as SQLnative client configuration properties but SQL Server accepts both encrypted connection and non-encrypted connections,why?(i have checked the encrypt connection of the connection properties of connect to server window). also when i run profiler, it can capture both T-SQL statements which has run against encrypted and non-encrypted connection and i expect the profiler should not be able to get the encrypted connection's T-SQL statement,am I right or something is wrong with my  configurations?--yousef

Encryption (System.Security.Cryptography) .Net 2.0

Hi, Query regarding cryptography.  I'm using .net cryptography to encrypt and decrypt files stored on disk on an asp.net website using .Net 2.0 framework.   The code (copied below) works fine to encrypt and decrypt pdf, tif, jpg, etc.  However when it comes to MS Word documents with embedded images and/or tables I get a "Bad data" error when decrypting.   The same document saved to rtf format is encrypted and decrypted without error.  Also simple formatted text documents in Word format (Office 2003) do not throw an error when being decrypted. Would someone care to point out where I'm going wrong? Thanks, code below   _________________________________    Public Sub Encrypt(ByVal Userid As Integer, ByVal FilePath As String)        'Encrypt the file        Try            Dim EncryptedFilePath As String = FilePath & "enc"            Dim clsNetEnCrypt As New NetEncrypt(User)            clsNetEnCrypt.Encrypt(FilePath, EncryptedFilePath)            'Remove the Unencrypted file
