Struct ECDSAVRF 

pub struct ECDSAVRF { /* private fields */ }

ECDSA-based VRF: proof = ECDSA sign, output = hash(proof)

Implementations

impl ECDSAVRF

pub fn new() -> Result<Self>

Generate new keypair (secp256k1)

pub fn from_signing_key_bytes(bytes: &[u8]) -> Result<Self>

Create from existing signing key bytes

pub fn prove(&self, data: &[u8]) -> Result<Vec<u8>>
