Struct nisty::PublicKey

pub struct PublicKey(_);

Public part of a keypair, a point on the curve. Verifies signatures.

Implementations

impl PublicKey

pub fn verify(
    &self,
    message: &[u8],
    signature: impl AsArrayRef<[u8; 64]>
) -> bool

Verify that a claimed signature for a message is valid.

pub fn verify_prehashed(
    &self,
    prehashed_message: &[u8; 32],
    signature: impl AsArrayRef<[u8; 64]>
) -> bool

Verify that a claimed signature for a prehashed message is valid.

pub fn compress(&self) -> [u8; 33]

This is the “SEC1” representation of a point on an elliptic curve, which is often used in IETF protocols.

Reference: https://tools.ietf.org/html/rfc5480#section-2.2

The first byte contains 2 + the “sign” of the y-coordinate (least significant byte). The following 32 bytes are the x-coordinate in big-endian representation.

Note: The “uncompressed” SEC1 format would prepend byte 0x4, it seems in this case at least everyone uses “raw” encoding: x || y

impl PublicKey

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

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

impl PublicKey

pub fn try_from_bytes(public_key_bytes: &[u8; 64]) -> Result<Self>

pub fn to_bytes(self) -> [u8; 64]

pub fn as_bytes(&self) -> &[u8; 64]
