Specifies a key for encrypting the database.

Syntax

Visual Basic

Public Property DatabaseKey As String

C#

public string  DatabaseKey  { get; set; }

Property value

A string specifying the encryption key. The default is a null reference (Nothing in Visual Basic) meaning no encryption.

Remarks

All connections must use the same key as was specified when the database was created. Lost or forgotten keys result in completely inaccessible databases.

As with all passwords, it is best to choose a key value that cannot be easily guessed. The key can be of arbitrary length, but generally the longer the key, the better, because a shorter key is easier to guess than a longer one. Using a combination of numbers, letters, and special characters decreases the chances of someone guessing the key.
