Struct VerificationKey

pub struct VerificationKey<D: Domain> { /* private fields */ }

A valid decaf377-rdsa verification key.

This type holds decompressed state used in signature verification; if the verification key may not be used immediately, it is probably better to use VerificationKeyBytes, which is a refinement type for [u8; 32].

Implementations

impl<D: Domain> VerificationKey<D>

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

Returns the byte encoding of the verification key.

This is the same as .into(), but does not require type inference.

impl VerificationKey<SpendAuth>

pub fn randomize(&self, randomizer: &Fr) -> VerificationKey<SpendAuth>

Randomize this verification key with the given randomizer.

Randomization is only supported for SpendAuth keys.

impl<D: Domain> VerificationKey<D>

pub fn verify(&self, msg: &[u8], signature: &Signature<D>) -> Result<(), Error>

Verify a purported signature over msg made by this verification key.

pub fn is_identity(&self) -> bool

Convenience method for identity checks.
