Key Property
The secret key for the symmetric algorithm.
Syntax
[VB.NET] Public Property Key As String Public Property KeyB As Byte()
[C#] public string Key {get; set;} public byte[] KeyB {get; set;}
Remarks
This secret key is used both for encryption and decryption. The secret key should be known only to the sender and the receiver. The legal key size varies depending on the algorithm.
If this property is left empty and KeyPassword is specified, a Key value will be generated by the component as necessary.
