// This is a sample script to illustrate how to use CAPICOM and C#. It creates a

//
// !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//
// To run this sample you need to have Microsoft Visual C# .NET
// To start: open the storesh.sln file in Visual Studio
//
// !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//
//
//  Try these commands:
//
//	help
//	dir
//	cd ..
//	cd ..\addressbook
//	dir -l
//	dir -subject John
//	cd \LocalMachine
//	cd \lm
//	display 3
//	view 2
//	import c:\home\temp\pfx1.pfx
//	export 7 c:\home\temp\itm.cer
//  pfxexport 11 c:\home\temp\foo.pfx secretpassword
//	rem 2
//  dir -issuer "Thawte"
//  dir -eku "Code Signing"
//  dir -eku 1.3.6.1.5.5.7.3.4

// Note: For simplicity, this script does not handle exceptions.
