* Private and public keys are asserted valid at the FFI boundary. Thus, before passing any
(untrusted) private or public key material across the boundary, ensure that they represent valid
(ie in-range) keys.
**It is highly recommended that you test any code which relies on the C (or C++) bindings in
valgrind, AddressSanitizer, MemorySanitizer, or other similar tools to ensure correctness.**
