Module Hkdf.MakeSource

Given a Hash function, get the HKDF

Parameters

module H : Digestif.S

Signature

Sourceval extract : ?salt:string -> string -> string

extract salt ikm is prk, the pseudorandom key of hash length octets. The salt is an optional non-secret random value, ikm the input key material.

Sourceval expand : prk:string -> ?info:string -> int -> string

expand prk info length is okm, the output keying material. Given the pseudorandom key of hash length (usually output of !extract step), and an optional context and application specific information info, the okm is generated.

  • raises Failure

    when length is negative or exceeds 255 * hash output size (the RFC 5869 limit).
