When you sign data, each column that you sign requires an extra column for that column s encrypted signature. If anyone updates a signed column value in a row, its value becomes unsynchronized with the corresponding encrypted signature s value. Someone can sign a row again after altering a column value, but the row s editor must have access to a valid certificate or asymmetric key to re-sign the signature for a row. You can sign a column value in a row with either the SignByAsymKey or SignByCert function, depending on whether you are using an asymmetric key or a certificate. Matching functions (VerifySignedByAsymKey and VerifySignedByCert) exist for verifying that a signature has not changed since it was last signed. The code in this section works with the SignedData table created in SettingUpEncSignDemo.sql. Three critical column values will be necessary for any application that uses signed data. The mysignature column has a varbinary type for holding the data signature. The mytext column contains the value that you sign. The certname column contains the name of the certificate used to generate the signature column value. A column for a certificate s name is not strictly necessary. This is obviously the case if you have only one certificate or your organization uses a specific certificate for each type of data it signs. how to make pdf password protected in c# Encrypt PDF Document in C# , VB.NET - E-Iceblue

Drag a FlowDecision activity below the Hello activity. The FlowDecision activity looks like a yellow diamond, much like a decision symbol in a normal flowchart diagram. In the Properties window, enter the condition as DateTime.Now.Hour >= 12. If you hover the mouse over the FlowDecision activity, you should see the connection points, as shown in Figure 3-6.

Note When working with tables with many rows, you may want to discover the smallest column width that allows your signing function to succeed without causing your column to overflow. In any event, the signature column width must be wider than the width of the data in the column for which the signature column validates no changes.
