function ~VRFProvider¶

~VRFProvider() override =default

function generateKeypair¶

virtual SR25519Keypair generateKeypair() const =0

Reimplemented by: sgns::crypto::VRFProviderImpl::generateKeypair

Generates random keypair for signing the message

function sign¶

virtual boost::optional< VRFOutput > sign(
    const base::Buffer & msg,
    const SR25519Keypair & keypair,
    const VRFThreshold & threshold
) const =0

Sign message using the given keypair and threshold.

Parameters:

msg Message bytes.
keypair SR25519 keypair.
threshold VRF threshold.

Return: Optional VRF output if threshold satisfied.

Reimplemented by: sgns::crypto::VRFProviderImpl::sign

    const base::Buffer & msg,
    const VRFOutput & output,
    const SR25519PublicKey & public_key,
    const VRFThreshold & threshold
) const =0

Verify VRF output against message and public key.

Parameters:

msg Message bytes.
output VRF output to verify.
public_key Public key to verify against.
threshold VRF threshold.

Return: Verification output.
