Type Library

RIPEMD128_Final

void RIPEMD128_Final( [in, out]RIPEMD128_Context* pContext, [out]RIPEMD128_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-128 message digest from the pContext context. The digest is retrieved in the pDigest memory buffer.

After the RIPEMD128_Final function is performed, the context is initialized for new calculations, as it would be called RIPEMD128_Init again.

Note. Before the first call to RIPEMD128_Update, RIPEMD128_UpdateStr, RIPEMD128_Final or RIPEMD128_FinalHex functions, the context must be initialized with RIPEMD128_Init.

VB Example

Private Sub MyButton_Click()

    Dim Context As RIPEMD128_Context

    Dim Digest As RIPEMD128_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

    RIPEMD128_Init Context

    'Update the context with first part

    Dim nFirstLen As Long

    nFirstLen = nLen / 3

    RIPEMD128_Update Context, MyBinData(1), nFirstLen

    'Update the context with second part

    RIPEMD128_Update Context, MyBinData(nFirstLen + 1), nLen - nFirstLen

    'Get the digest

    RIPEMD128_Final Context, Digest

    'Show the hexadecimal representation of the digest

    MsgBox QHASH_ConvertToHex(Digest.Value(0), RIPEMD128_DIGESTSIZE, True)

End Sub
