Expand description

Deterministically generate ephemeral scalar k.

Accepts the following parameters and inputs:

  • x: secret key
  • n: field modulus
  • h: hash/digest of input message: must be reduced modulo n in advance
  • data: additional associated data, e.g. CSRNG output used as added entropy
