Actually 'we' (crypto community) talk about crypto-suites, as you have 
to look at all the pieces involved. If everything is not disclosed (like 
with Skype), then you just don't know where the weakness may be.

SSH, IPsec (watch out for the 'Null' cipher :) ), TLS (some of the 
suites are too weak to talk about), and HIP are all well-rounded 
security protocols. I have worked on all of them.
