Constructors, destructors, conversion operators

VrfSigningKey(std::span<const uint8_t, VRF_SECRET_KEY_SIZE> key_bytes) explicit

Construct a new VrfSigningKey object from a byte vector.

Public functions

auto bytes() const →  const VRFKeyByteArray& constexpr

Return a constant reference to the private key secure byte array.

auto constructProof(std::span<const uint8_t> msg) →  std::array< uint8_t, VRF_PROOF_SIZE > -> auto

Construct a VRF proof from an initial message.

auto hash(std::span<const uint8_t> msg) →  std::array< uint8_t, VRF_PROOF_HASH_SIZE > -> auto

Compute the VRF hash of a message.

auto isValid() const →  bool

Ensure the key is a valid ed25519 key.

auto publicKey() const →  VRFPublicKey

Derive the public key paired with this private key.

void saveToFile(std::string_view fpath) const

auto sign(std::span<const uint8_t> msg) const →  std::array< uint8_t, ed25519::SIGNATURE_SIZE > -> auto

Generate a message signature from the private key.

auto verificationKey() const →  VrfVerificationKey

Derive the corresponding verification (public) key.

auto verifyProof(std::span<const uint8_t> msg, std::span<const uint8_t, VRF_PROOF_SIZE> proof) const →  bool
