Struct redjubjub::PublicKey

pub struct PublicKey<T: SigType> { /* fields omitted */ }

A valid RedJubJub public key.

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

Consensus properties

The TryFrom<PublicKeyBytes> conversion performs the following Zcash consensus rule checks:

1. The check that the bytes are a canonical encoding of a public key;
2. The check that the public key is not a point of small order.

Methods

impl PublicKey<SpendAuth>

pub fn randomize(&self, randomizer: &Randomizer) -> PublicKey<SpendAuth>

Randomize this public key with the given randomizer.

Randomization is only supported for SpendAuth keys.

impl<T: SigType> PublicKey<T>

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

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