Struct solana_libra_nextgen_crypto::vrf::ecvrf::VRFPublicKey

pub struct VRFPublicKey(_);

An ECVRF public key

Methods

impl VRFPublicKey

pub fn verify(&self, proof: &Proof, alpha: &[u8]) -> Result<()>

Given a Proof and an input, returns whether or not the proof is valid for the input and public key

Methods from Deref<Target = ed25519_PublicKey>

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

Convert this public key to a byte array.

pub fn as_bytes(&'a self) -> &'a [u8; 32]

View this public key as a byte array.

pub fn verify(
    &self,
    message: &[u8],
    signature: &Signature
) -> Result<(), SignatureError>

Verify a signature on a message with this keypair's public key.

Return

Returns Ok(()) if the signature is valid, and Err otherwise.

pub fn verify_prehashed<D>(
    &self,
    prehashed_message: D,
    context: Option<&[u8]>,
    signature: &Signature
) -> Result<(), SignatureError> where
    D: Digest<OutputSize = UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>>, 

Verify a signature on a prehashed_message using the Ed25519ph algorithm.

Inputs

• prehashed_message is an instantiated hash digest with 512-bits of output which has had the message to be signed previously fed into its state.
• context is an optional context string, up to 255 bytes inclusive, which may be used to provide additional domain separation. If not set, this will default to an empty string.
• signature is a purported Ed25519ph Signature on the prehashed_message.

Returns

Returns true if the signature was a valid signature created by this Keypair on the prehashed_message.
