Where to put new classes in hierarchy?

[Mikael Svensson]

Hello everybody

Quick question about the library hierarchy of Minisip:

I'm about to develop a certificate locater (automatic certificate 
downloader) and a corresponding certificate cache (to avoid using the 
locater). This means that my new classes will be dependent on libmcrypto 
and libmnetutil. My first idea was then to put these new features in the 
libmcrypto library, but...

Then I realized that a certificate cache can be made more generic and 
then hold other types of cachable items as well, e.g. "directory service 
search results". This led me to this conclusion:

libmnetutil: add "directory service search result" class
libmcrypto: add "certificate cache item" class (dependency: libmnetutil)
libminisip: add "cache management" class (dependencies: libmcrypto and 
libmnetutil)

Would this "comply" with how the Minisip "depenceny tree" is designed?

Mikael
