[C#]

[DllImport(WINLICENSE_SDK_DLL, CallingConvention = CallingConvention.StdCall)]

   public static extern void WLBufferCrypt(IntPtr Buffer, int BufferSize, string password);

 

[Visual Basic]

<DllImport("WinlicenseSDK.dll", CallingConvention:=CallingConvention.StdCall)>

   Public Shared Sub WLBufferCrypt(Buffer As IntPtr, BufferSize As Integer, Password As String)

End Sub

 

Parameters

 

pBuffer

[in] Pointer to a buffer to encrypt.

 

BufferLength

[in] Size of buffer to encrypt.

 

pPassword

[in] Pointer to a null terminated string with the encryption password.

 

 

Return Values

 

This function has no return values.

 

 

Remarks

 

The current encryption algorithm works with block multiplication factor 4 bytes. If the length of the buffer to encrypt is not factor 4 bytes, the remaining 3, 2 or 1 bytes won't be encrypted. You might want to padd first the buffer to 4 bytes multiple (adding garbage data at the end) before calling WLBufferCrypt.
