One idea: take a look at the OpenSSL API documentation. Since that seems to be the de facto floor SSL implementation on every other platform, similar capabilities would probably be desirable. If you're pressed for time, that basically boils down to exposing the encrypted state of the connection (on/off), trust level (algorithm/strength in bits), and endpoint verification (site/user) to the app. If we had a way to interface with the crypto facilities (eg a CSL implementation of the OpenCryptoKit API you supply on Linux), porting OpenSSL to CMS would be pretty simple.
