The libsodium's docs [1] are awesome in this regard, particularly the sections (and subsections) on secret-key and public-key cryptography.
If you study those docs you'll get the modern terminology used by most other libraries as well as the intended use-cases for the different cryptographic constructs.
Your examples point to public-key use-cases, and I don't see any public-key crypto support in this Orion library, so probably you just wouldn't use it ;)
