MD5_Calculate

void MD5_Calculate( [out]MD5_Digest* pDigest, [ in , size_is( nSrcLength ) ] const void* pSrc, [ in ] int nSrcLength );

Parameters

 pDigest

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

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

 pSrc

    [in] A continuous memory block for which to calculate the message digest.

 nSrcLength

    [in] Length in bytes of the memory block. 

Remarks

Calculates the MD5 message digest for the  pSrc memory block. The digest is retrieved in the pDigest memory buffer.

VB Example

Private Sub MyButton_Click()   

    Dim Digest As MD5_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    

    'Get the digest

    MD5_Calculate Digest, MyBinData(1), nLen

    'Show the hexadecimal representation of the digest

    MsgBox QHASH_ConvertToHex(Digest.Value(0), MD5_DIGESTSIZE, True)

End Sub
