You already answered your own question.

The following namespaces can be used to access SQL Server 2005 programmatically: Microsoft.SqlServer.management Microsoft.SqlServer.Management.NotificationServices Microsoft.SqlServer.Management.Smo Microsoft.SqlServer.Management.Smo.Agent Microsoft.SqlServer.Management.Smo.Broker Microsoft.SqlServer.Management.Smo.Mail Microsoft.SqlServer.Management.Smo.RegisteredServers Microsoft.SqlServer.Management.Smo.Wmi Microsoft.SqlServer.Management.Trace Backup bkpDBFull = new Backup(); /* Specify whether you want to back up database or files or log */ bkpDBFull.Action = BackupActionType.Database; /* Specify the name of the database to back up */ bkpDBFull.Database = myDatabase.Name; /* You can take backup on several media type (disk or tape), here I am * using File type and storing backup on the file system */ bkpDBFull.Devices.AddDevice(@"D:\AdventureWorksFull.bak", DeviceType.File); bkpDBFull.BackupSetName = "Adventureworks database Backup"; bkpDBFull.BackupSetDescription = "Adventureworks database - Full Backup"; /* You can specify the expiration date for your backup data * after that date backup data would not be relevant */ bkpDBFull.ExpirationDate = DateTime.Today.AddDays(10); /* You can specify Initialize = false (default) to create a new * backup set which will be appended as last backup set on the media.

First of all you need to understand difference between Hashing and Encryption. Based on your requirement you need to choose correct method to secure your data. Check this[^] thread to understand why MD5 is irreversible.

Quote: MD5 is officially "broken" and should not be used for new designs - SHA is preferred Thanks for this information. I am not aware about that. You deserve Up vote.
