void MD2_FinalHex( [in,out]MD2_Context* pContext,[out]MD2_HexDigest* pDigest, [ in ]boolean bUpper );



    [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 as an ASCII null-terminated string.

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


    [in] Uppercase flag. If bUpper is False, the received message digest represents a lowercase string, otherwise it represents an uppercase string.


Call this function to retrieve the MD2 message digest from the pContext context. The digest is retrieved as an ASCII null-terminated hexadecimal string in the pDigest memory buffer.

After the MD2_FinalHex 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_HexDigest
    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_FinalHex Context, Digest, True
    'Show the hexadecimal representation of the digest
    MsgBox QHASH_ASCIItoBSTR(Digest.Value(0))
End Sub
