Summary: Used to pass data to and from CryptProtectData, CryptUnprotectData

!!!!C# Signature:
 [StructLayout(LayoutKind.Sequential, CharSet=CharSet.Unicode)]
 private struct DATA_BLOB {
 	public int cbData;
 	public IntPtr pbData;
 }
!!!!VB .NET Signature:
 <StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Unicode)> Structure DATA_BLOB
        Public cbData As Integer
        Public pbData As IntPtr
 End Structure
!!!!Notes:
None.

!!!!Tips & Tricks:
Remember that DATA_BLOB.pbData for the output parameters of the CryptProtectData and CryptUnprotectData functions will point to a block of unmanaged memory that needs to be cleaned up using a call to LocalFree from kernel32. You will of course have to use pinvoke to call LocalFree.
