Generates a combined-entropy key for use with the DES or Triple-DES algorithms. This function will always return a key that is not considered weak by TripleDES.IsWeakKey().
Namespace: Microsoft.IdentityModel
Assembly: Microsoft.IdentityModel (in microsoft.identitymodel.dll)

Usage

Visual Basic 
Dim keySizeInBits As Integer
Dim senderEntropy As Byte()
Dim receiverEntropy As Byte()
Dim returnValue As Byte()

returnValue = KeyGenerator.GenerateDESKey(keySizeInBits, senderEntropy, receiverEntropy)
