    <p>I'm not sure what I'm doing wrong, the encryption it seems to work but when you get to the decryption says bad data when trying to deserialize it, not sure what I'm doing wrong. I'm new at doing encryption so if it's something really simple I'm sorry. </p> <pre><code> public byte[] Serialize(object obj, string key) { byte[] returnBytes; using (MemoryStream memory = new MemoryStream()) { UTF8Encoding UTF8 = new UTF8Encoding(); TripleDESCryptoServiceProvider crypt = new TripleDESCryptoServiceProvider(); MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider(); byte[] pass = provider.ComputeHash(UTF8.GetBytes(key)); crypt.Key = pass; crypt.Mode = CipherMode.ECB; crypt.Padding = PaddingMode.PKCS7; using (CryptoStream stream = new CryptoStream(memory, crypt.CreateEncryptor(), CryptoStreamMode.Write)) { BinaryFormatter formatter = new BinaryFormatter(); formatter.Serialize(stream, obj); stream.Close(); memory.Close(); } returnBytes = memory.ToArray(); } return returnBytes; } public object Deserialize(byte[] inBytes, string key) { object returnObj; using (MemoryStream memory = new MemoryStream()) { UTF8Encoding UTF8 = new UTF8Encoding(); TripleDESCryptoServiceProvider crypt = new TripleDESCryptoServiceProvider(); MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider(); byte[] pass = provider.ComputeHash(UTF8.GetBytes(key)); crypt.Key = pass; crypt.Mode = CipherMode.ECB; crypt.Padding = PaddingMode.PKCS7; using (CryptoStream stream = new CryptoStream(memory, crypt.CreateDecryptor(), CryptoStreamMode.Read)) { BinaryFormatter formatter = new BinaryFormatter(); returnObj = formatter.Deserialize(stream); stream.Close(); memory.Close(); } return returnObj; } } </code></pre> <p>This code i did a while back works on strings</p> <pre><code> public string encrypt(string message, string password) { byte[] result; UTF8Encoding UTF8 = new UTF8Encoding(); MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider(); byte[] key = provider.ComputeHash(UTF8.GetBytes(password)); TripleDESCryptoServiceProvider algorithm = new TripleDESCryptoServiceProvider(); algorithm.Key = key; algorithm.Mode = CipherMode.ECB; algorithm.Padding = PaddingMode.PKCS7; byte[] data = UTF8.GetBytes(message); try { ICryptoTransform encryptor = algorithm.CreateEncryptor(); result = encryptor.TransformFinalBlock(data, 0, data.Length); } finally { algorithm.Clear(); provider.Clear(); } return Convert.ToBase64String(result); } public string decrypt(string message, string passsword) { byte[] result; UTF8Encoding UTF8 = new UTF8Encoding(); MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider(); byte[] key = provider.ComputeHash(UTF8.GetBytes(passsword)); TripleDESCryptoServiceProvider algorithm = new TripleDESCryptoServiceProvider(); algorithm.Key = key; algorithm.Mode = CipherMode.ECB; algorithm.Padding = PaddingMode.PKCS7; byte[] data = Convert.FromBase64String(message); try { ICryptoTransform decryptor = algorithm.CreateDecryptor(); result = decryptor.TransformFinalBlock(data, 0, data.Length); } finally { algorithm.Clear(); provider.Clear(); } return UTF8.GetString(result); } </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.
