Only applies to algorithms that support it. Both raw private and public keys can be obtained for X25519, Ed25519, X448, Ed448. Raw private keys only can be obtained for HMAC, Poly1305 and SipHash Fixes #6259 Reviewed-by: Rich Salz <rsalz@openssl.org> Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/6394)
