DH (mavkit-libs.Mavryk_sapling.Core.Raw.DH)

type esk = R.esk

val esk_encoding : R.esk Data_encoding.encoding

val esk_random : unit -> R.esk

type epk = R.epk

val epk_encoding : R.epk Data_encoding.encoding

val derive_ephemeral : Viewing_key.address -> R.esk -> R.epk

Derives the public part of the DH for the sender. (ie. epk is used for symkey_receiver).

val kdf_key : string

val symkey_sender : R.esk -> R.pkd -> Mavryk_crypto.Crypto_box.Secretbox.key

Derives a symmetric key to be used to create the ciphertext on the sender side.

val symkey_receiver : R.epk -> R.ivk -> Mavryk_crypto.Crypto_box.Secretbox.key

val symkey_out : 
  R.ovk ->
  (R.cv * R.commitment * R.epk) ->
  Mavryk_crypto.Crypto_box.Secretbox.key
