pub struct Pair { /* private fields */ }
Expand description

Bandersnatch secret key.

Implementations§

source§

impl Pair

source

pub fn seed(&self) -> [u8; 32]

Get the key seed.

source§

impl Pair

source

pub fn make_bytes<const N: usize>( &self, context: &'static [u8], input: &VrfInput ) -> [u8; N]

Generate an arbitrary number of bytes from the given context and VRF input.

source§

impl Pair

source

pub fn ring_vrf_sign( &self, data: &VrfSignData, prover: &RingProver<Fp<MontBackend<FrConfig, 4>, 4>, KZG<Bls12<Config>>, BandersnatchConfig> ) -> RingVrfSignature

Produce a ring-vrf signature.

The ring signature is verifiable if the public key corresponding to the signing Pair is part of the ring from which the RingProver has been constructed. If not, the produced signature is just useless.
