Entropy Constructor (Byte[], SecurityToken)

Initializes a new instance of the Entropy class with the specified entropy value, encrypted using the specified security token.

Namespace: Microsoft.Web.Services3.Security
Assembly: Microsoft.Web.Services3 (in microsoft.web.services3.dll)

Usage

'Usage
Dim key() As Byte
Dim encryptingToken As SecurityToken
Dim entropy1 As New Entropy(key, encryptingToken)

Syntax

'Declaration
Public Sub New( _
    ByVal key() As Byte, _
    ByVal encryptingToken As SecurityToken _
)

public Entropy(
    byte[] key, 
    SecurityToken encryptingToken
);

public:
Entropy(
    array<unsigned char>^ key, 
    SecurityToken^ encryptingToken
);

public Entropy(
    ubyte[] key, 
    SecurityToken encryptingToken
);

public function Entropy(
     key : Byte[], 
     encryptingToken : SecurityToken
);

Parameters

• key
  An array of type Byte that contains the entropy value.

• encryptingToken
  The SecurityToken that is used to encrypt the entropy value.

Exceptions

Exception type	Condition
ArgumentNullException	key is null. -or- key is zero length.
ArgumentNullException	encryptingToken is null.

Remarks

This constructor sets the value of the EncryptedKey property to an EncryptedKey that contains the entropy value specified in the key parameter. When the Entropy class is serialized into XML, the entropy value is encrypted using the security token specified in the encryptingToken parameter and placed in an <EncryptedKey> child element. Typically, the encryptingToken parameter is the public key of the security token service, so that only the security token service can decrypt the entropy value.
