about

hkdf_sha512.nx -- HKDF-SHA-512 (RFC 5869). Final HKDF variant, parallel to hkdf.nx (SHA-256) and hkdf_sha384.nx (SHA-384). Used where a downstream primitive requires the full 512-bit output width or where the whole key ladder is anchored on SHA-512. Output capacity: 255 * 64 = 16320 bytes. Ample for any TLS / SSH session derivation.
