Is there a reference that maps OIDs to terms used in Microsoft documentation like "Server Authentication" or "Secure Email"?
Server Authentication: 1.3.6.1.5.5.7.3.1
Client Authentication: 1.3.6.1.5.5.7.3.2
Secure Email: 1.3.6.1.5.5.7.3.4
Data Encipherment: 1.3.6.1.4.1.311.10.3.4
Key Encipherment: ?
Digital Signature: ?
I am using these OIDs to generate test certificates with makecert.exe.
There is a support document in the Microsoft knowledge base: http://support.microsoft.com/kb/287547
