The source code in this directory can be used to build a DLL that encodes and

decodes several different types of X509 Certificate Extensions, in support of

Policy or Exit Modules for Microsoft Certificate Services, or for any other

code that needs to encode or decode Certificate Extensions.



It is meant to run on Windows NT 4.0 with SP3 or later or on Windows 2000 only.

Certificate Services must already be installed for this DLL to be used by a

Policy or Exit Module.  This DLL implements several COM interfaces to allow C++

or Visual Basic code to encode extensions without having any knowledge of the

Crypto APIs, using only basic COM support and the BSTR data type to represent

binary encoded extensions.



For examples using these interfaces to encode Certificate Extensions, see the

C++ or Visual Basic sample Policy Modules in sibling directories.  The

following routines in the C++ Policy Module encode extensions using interfaces

defined here:

    CCertPolicy::_AddRevocationExtension (ICertEncodeCRLDistInfo)

    CCertPolicy::_AddCertTypeExtension (ICertEncodeBitString)

    CCertPolicy::_AddSubjectAltNameExtension (ICertEncodeAltName)



The Visual Basic policy module encodes the following extension types using

interfaces defined here:

    ICertEncodeStringArray



Once the certenc.dll DLL is built, its COM interface must be registered

via the following command:

    regsvr32 certenc.dll



If you use the certenc.dll built from these SDK sources with the Visual Basic

policy module (policyvb.dll), you must use the SDK version of the Visual Basic

policy module.  This is because the Visual Basic policy module shipped with

Cert Server 1.0 references a sample interface that is no longer provided as

part of certenc.dll.
