Module `Hacl_star__Hacl.HKDF_SHA2_512`

Portable C implementation of HKDF using SHA2-512

type bytes = Hacl_star.SharedDefs.CBytes.t

val extract : salt:bytes -> ikm:bytes -> bytes: extract salt ikm computes a pseudorandom key using input key material ikm and salt salt.

val expand : prk:bytes -> info:bytes -> size:int -> bytes: expand prk info size expands the pseudorandom key prk, taking the info string info into account and returns a buffer of size bytes.

module Noalloc : sig ... end: Versions of these functions which write their output in a buffer passed in as an argument
