VB Script - VBA - ActiveX - Encryption/Cryptography question

Background :      The company is currently using a "discontinued ActiveX control" (CAPICOM)  and considering WIN7 deprecation issues we've been asked to come up with a plan to migrate off of the  "discontinued ActiveX control" cryptographic library.  

Note :  The business unit currently use SHA1 hashing and AES256 encryption.  

The solution we're seeking to migrate to must use a standard library to implement cryptography.


Microsoft discusses Alternatives to Using Capicom here but we do not see anything that applies to VBA:  http://msdn.microsoft.com/en-us/library/cc778518(VS.85).aspx

 
Question  :    Is there a standard way in VBA code in MS Access or Excel to implement hashing and encryption by setting a reference (early or late binding) or a call to Windows API or some other way?

 i.e..

Call a Windows API function by Declaration:  eg: Private Declare Function GetSystemMenu Lib "user32" (ByVal hWnd As Long, ByVal wRevert As Long) As Long

Early-bind a library by setting a References in Tools.References

Late-bind a library:  Set objVar = CreateObject(“ObjectName.Here”)
