TimeStamp.HashDelegate Delegate

In This Topic

Represents a delegate used to calculate the hash over data. The data can be represented by an array of bytes or by a System.IO.Stream.

Outputs the hash value and the hash algorithm OID.

Syntax

Visual Basic
C#

'Declaration
 
Public Delegate Sub TimeStamp.HashDelegate( _
   ByVal dataToHash() As System.Byte, _
   ByVal streamToHash As System.IO.Stream, _
   ByRef hash() As System.Byte, _
   ByRef hashAlgorithmOid As OID _
)

public delegate void TimeStamp.HashDelegate( 
   System.byte[] dataToHash,
   System.IO.Stream streamToHash,
   out System.byte[] hash,
   out OID hashAlgorithmOid
)

Parameters

dataToHash: The byte array containing the data. If a null reference (Nothing in Visual Basic), streamToHash will be used.
streamToHash: The stream containing the data. If a null reference (Nothing in Visual Basic), dataToHash will be used.
hash: OUT: The data hash value.
hashAlgorithmOid: OUT: The hash algorithm OID.
