Detailed Description¶

class sgns::GeniusSigner;

Owns a Genius keypair without imposing account persistence or lifecycle concerns.

GeniusAccount composes this type, while short-lived signing workflows can use it directly without touching secure storage.

The keypair is held as a raw secp256k1 secret key so that this component depends only on libsecp256k1, not on the crypto3-based ProofSystem.

Public Types Documentation¶

using PrivateKey¶

using sgns::GeniusSigner::PrivateKey =  std::array<uint8_t, PRIVATE_KEY_SIZE>;

Big-endian secp256k1 secret key, matching libsecp256k1's own encoding.

Public Functions Documentation¶

function Generate¶

static GeniusSigner Generate()

Generate a fresh, in-memory-only keypair.

function VerifySignature¶

static bool VerifySignature(
    const std::string & address,
    std::string_view signature,
    const std::vector< uint8_t > & data
)

Verify a canonical Genius signature.

function VerifySignature¶

static bool VerifySignature(
    const std::string & address,
    const std::vector< uint8_t > & signature,
    const std::vector< uint8_t > & data
)

Verify a canonical Genius signature supplied as bytes.

function GeniusSigner¶

explicit GeniusSigner(
    const PrivateKey & private_key
)

Take ownership of an existing secret key.

function GetAddress¶

std::string GetAddress() const

Return the 128-character hexadecimal Genius public address.

The address is the uncompressed public key (X followed by Y, both big-endian) without the leading 0x04 tag, hex encoded in lower case. Empty when the secret key is not a valid secp256k1 scalar.

function Sign¶

std::vector< uint8_t > Sign(
    const std::vector< uint8_t > & data
) const

Sign bytes using the canonical Genius signature encoding.

variable PRIVATE_KEY_SIZE¶

static constexpr size_t PRIVATE_KEY_SIZE = 32;
