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

VRF secret key for generating proofs.

Implementations§

Source§

impl VrfSecretKey

Source

pub fn generate() -> Self

Generate a new random VRF secret key.

Source

pub fn from_bytes(bytes: &[u8; 32]) -> Self

Create VRF secret key from 32 bytes.

Source

pub fn public_key(&self) -> VrfPublicKey

Get the corresponding public key.

Source

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

Convert to bytes.

Source

pub fn prove(&self, input: &[u8]) -> VrfProof

Prove and compute VRF output for given input.

This generates a proof that the output was correctly computed, and returns both the proof and the deterministic pseudorandom output.

Source

pub fn prove_output(&self, input: &[u8]) -> [u8; 32]

Prove and return only the VRF output (convenience method).

Source

pub fn prove_with_domain(&self, domain: &[u8], input: &[u8]) -> VrfProof

Prove with domain separation for different use cases.

This allows using the same key for different purposes without risk of cross-protocol attacks.
