RIPEMD320_Final

void RIPEMD320_Final( [in, out]RIPEMD320_Context* pContext, [out]RIPEMD320_Digest* pDigest );
 

Parameters

pContext

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

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

 pDigest

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

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

Remarks

Call this function to retrieve the RIPEMD-320 message digest from the pContext context. The digest is retrieved in the pDigest memory buffer.

After the RIPEMD320_Final function is performed, the context is initialized for new calculations, as it would be called RIPEMD320_Init again.

Note. Before the first call to RIPEMD320_Update, RIPEMD320_UpdateStr, RIPEMD320_Final or RIPEMD320_FinalHex functions, the context must be initialized with RIPEMD320_Init.

VB Example

Private Sub MyButton_Click()   
    Dim Context As RIPEMD320_Context
    Dim Digest As RIPEMD320_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
    RIPEMD320_Init Context
    'Update the context with first part
    Dim nFirstLen As Long
    nFirstLen = nLen / 3
    RIPEMD320_Update Context, MyBinData(1), nFirstLen
    'Update the context with second part
    RIPEMD320_Update Context, MyBinData(nFirstLen + 1), nLen - nFirstLen
    'Get the digest
    RIPEMD320_Final Context, Digest
    'Show the hexadecimal representation of the digest
    MsgBox QHASH_ConvertToHex(Digest.Value(0), RIPEMD320_DIGESTSIZE, True)
End Sub
