copied!<p>There are different ways to create a random piece of data that can be used for salting. The most common ones are:</p> <ul> <li>Creating a random GUID by using the <code>Guid</code> type</li> <li>Creating a random string of digits by using the <code>RNGCryptoServiceProvider</code> class</li> </ul> <p>To create a new random GUID, we invoke the <code>NewGuid</code> method on the <code>Guid</code> type. Once generated, we simply append the salt to the string to be encrypted.</p> <pre><code>string saltAsString = Guid.NewGuid().ToString(); </code></pre> <p>For creating a random string of digits by using the <code>RNGCryptoServiceProvider</code> class, we first initialize a provider and a <code>byte</code> array, and then invoke the <code>GetBytes</code> method on our provider instance.</p> <pre><code>byte[] saltInBytes = new byte[8]; RNGCryptoServiceProvider saltGenerator = new RNGCryptoServiceProvider(); saltGenerator.GetBytes(saltInBytes); string saltAsString = Convert.ToBase64String(saltInBytes); </code></pre> <p>The following code is a modified version of the previous snippet to demonstrate salting.</p> <pre><code>public void HashText() { string textToHash = "password"; string saltAsString = Guid.NewGuid().ToString(); byte[] byteRepresentation = UnicodeEncoding.UTF8.GetBytes(textToHash + saltAsString); byte[] hashedTextInBytes = null; MD5CryptoServiceProvider myMD5 = new MD5CryptoServiceProvider(); hashedTextInBytes = myMD5.ComputeHash(byteRepresentation); string hashedText = Convert.ToBase64String(hashedTextInBytes); // will display X03MO1qnZdYdgyfeuILPmQ== MessageBox.Show(hashedText); } </code></pre>
