    <p>I have the following decryption method that seems to work fine except it is only returning 16 bytes instead of 32 it should I've stared at it too long and can't figure out what I've done wrong. I'm hoping a different set of eyes will help. Thanks.</p> <pre><code>private string Decrypt(string dataToDecrypt, string password, string salt) { //Generate a Key based on a Password, Salt and HMACSHA1 pseudo-random number generator Rfc2898DeriveBytes rfc2898 = new Rfc2898DeriveBytes(password, Encoding.UTF8.GetBytes(salt)); //Create AES algorithm with 256 bit key and 128-bit block size using (var aes = new AesManaged()) { // These two values are hard coded in Silverlight //aes.Mode = CipherMode.CBC; //aes.Padding = PaddingMode.PKCS7; aes.Key = rfc2898.GetBytes(aes.KeySize / 8); aes.IV = rfc2898.GetBytes(aes.BlockSize / 8); //Create Memory and Crypto Streams using (var memoryStream = new MemoryStream()) { using (var cryptoStream = new CryptoStream(memoryStream, aes.CreateDecryptor(), CryptoStreamMode.Write)) { //Decrypt Data byte[] data = Convert.FromBase64String(dataToDecrypt); cryptoStream.Write(data, 0, data.Length); // cryptoStream.FlushFinalBlock(); //Return Decrypted String byte[] decryptBytes = memoryStream.ToArray(); string decrypted = Encoding.UTF8.GetString(decryptBytes, 0, decryptBytes.Length); return decrypted; } // using (cryptoStream = new CryptoStream(memoryStream, aes.CreateDecryptor(), CryptoStreamMode.Write)) } // using (memoryStream = new MemoryStream()) } // using (aes = new AesManaged()) } // string Decrypt(string dataToDecrypt, string password, string salt) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
