Description
Description
Currently, cryptolib only has a function to create a public key from a given private key (otcrypto_ed25519_public_key_from_private()). For consistency reasons (i.e., ECC P256/P384), consider adding a new function that enables us to also create private keys.
Note that the user already can create private keys without this function already.

Research direction
Start by comparing the existing ECC P256/P384 private-key creation APIs with otcrypto_ed25519_public_key_from_private(). Determine the intended Ed25519 private-key API and its consistency requirements; the work is done when the proposed function is defined and validated against the existing cryptolib behavior.
