Struct VerifyingKey 

pub struct VerifyingKey(/* private fields */);

An ECDSA verifying key: a point on the curve.

Parsing does not validate the point; the ECDSA driver does, when it is used. Convert to a Point to validate it explicitly.

Implementations

impl VerifyingKey

pub fn from_xy(x: &[u8; 32], y: &[u8; 32]) -> Self

Build a verifying key from its coordinates.

pub fn from_sec1(bytes: &[u8; 65]) -> Result<Self, Error>

Parse an uncompressed SEC1 encoding (0x04 || x || y).

pub fn to_sec1(&self) -> [u8; 65]

The uncompressed SEC1 encoding (0x04 || x || y).

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

The X coordinate, big-endian.

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

The Y coordinate, big-endian.

pub fn as_driver(&self) -> &P256Point

The driver representation.

pub fn verify_prehash( &self, digest: &[u8; 32], signature: &Signature, ) -> Result<(), Error>

Verify the signature of a message digest.

Both low-S and high-S signatures are accepted.
