void RIPEMD256_Final( [in, out]RIPEMD256_Context* pContext, [out]RIPEMD256_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 RIPEMD-256 message digest from the pContext context. The digest is retrieved in the pDigest memory buffer.

After the RIPEMD256_Final function is performed, the context is initialized for new calculations, as it would be called RIPEMD256_Init again.

Note. Before the first call to RIPEMD256_Update, RIPEMD256_UpdateStr, RIPEMD256_Final or RIPEMD256_FinalHex functions, the context must be initialized with RIPEMD256_Init.

VB Example

Private Sub MyButton_Click()   
    Dim Context As RIPEMD256_Context
    Dim Digest As RIPEMD256_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
    RIPEMD256_Init Context
    'Update the context with first part
    Dim nFirstLen As Long
    nFirstLen = nLen / 3
    RIPEMD256_Update Context, MyBinData(1), nFirstLen
    'Update the context with second part
    RIPEMD256_Update Context, MyBinData(nFirstLen + 1), nLen - nFirstLen
    'Get the digest
    RIPEMD256_Final Context, Digest
    'Show the hexadecimal representation of the digest
    MsgBox QHASH_ConvertToHex(Digest.Value(0), RIPEMD256_DIGESTSIZE, True)
End Sub
