The controls are easier to understand and use currently.
The advantage of params is that you can batch them, so that the order no longer matters during setup (e.g- I need to set EVP_MD first).

The params are not being used in anger yet.
My main problem with the params is that no data is set into them - only pointers to the data blob.
I find this to be a confusing interface which hurts my (tiny) brain (especially with types like strings)
I would prefer base types (like int to just be embedded in the set data - even if that meant allocs are needed).
My concern is that is the end user is supposed to use what we have currently, there are going to be many issues.
