Required Associated Types

Required Methods

Generates proof from a private key and a message

Arguments:
  • pkey: a private key
  • alpha_string: octet string message represented by a slice
Returns:
  • if successful, a vector of octets representing the VRF proof

Generates VRF hash output from the provided proof

Arguments:
  • pi_string: generated VRF proof
Returns:
  • the VRF hash output

Verifies the provided VRF proof and computes the VRF hash output

Arguments:
  • public_key: a public key
  • alpha_string: VRF hash input, an octet string
  • pi_string: proof to be verified, an octet string
Returns:
  • if successful, a vector of octets with the VRF hash output
