What you ask for does not quite make sense. What is the overall task you intend to perform, can you provide a bit more context?
For instance, we have a sample in the SDK performing Elliptic-curve Diffie-Hellman key exchange. Calculations revolving around keys, points, etc. on the elliptic curve are part of what is performed under-the-hood when cryptography APIs are used, but there should be no need to perform individual sub-steps of those algorithms manually.
