void MD2_Final( [in, out]MD2_Context* pContext, [out]MD2_Digest* pDigest );



    [in/out] A memory buffer that is used as the context.

     Note. All predefined types are specified in the Predefined Types List.


    [out] A memory buffer that will receive the message digest.

     Note. All predefined types are specified in the Predefined Types List.


Call this function to retrieve the MD2 message digest from the pContext context. The digest is retrieved in the pDigest memory buffer.

After the MD2_Final function is performed, the context is initialized for new calculations, as it would be called MD2_Init again.

Note. Before the first call to MD2_Update, MD2_UpdateStr, MD2_Final or MD2_FinalHex functions, the context must be initialized with MD2_Init.

VB Example

Private Sub MyButton_Click()   
    Dim Context As MD2_Context
    Dim Digest As MD2_Digest
    Dim MyStrData As String
    MyStrData = "Hello World!"
    Dim nLen As Long
    nLen = Len(MyStrData)
    'Convert the string to byte array
    Dim MyBinData() As Byte
    ReDim MyBinData(1 To nLen)    
    For i = 1 To nLen
        MyBinData(i) = Asc(Mid(MyStrData, i, 1))
    Next i    
    'Initialize the context
    MD2_Init Context
    'Update the context with first part
    Dim nFirstLen As Long
    nFirstLen = nLen / 3
    MD2_Update Context, MyBinData(1), nFirstLen
    'Update the context with second part
    MD2_Update Context, MyBinData(nFirstLen + 1), nLen - nFirstLen
    'Get the digest
    MD2_Final Context, Digest
    'Show the hexadecimal representation of the digest
    MsgBox QHASH_ConvertToHex(Digest.Value(0), MD2_DIGESTSIZE, True)
End Sub
