Struct VerifyingKey

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

Available on crate features ecdsa-core and ecdsa only.

ECDSA/P-521 verification key (i.e. public key)

Implementations

impl VerifyingKey

pub fn from_sec1_bytes(bytes: &[u8]) -> Result<Self>

Initialize VerifyingKey from a SEC1-encoded public key.

pub fn from_affine(affine: AffinePoint) -> Result<Self>

Initialize VerifyingKey from an affine point.

Returns an Error if the given affine point is the additive identity (a.k.a. point at infinity).

pub fn from_encoded_point(public_key: &EncodedPoint) -> Result<Self>

Initialize VerifyingKey from an EncodedPoint.

pub fn to_encoded_point(&self, compress: bool) -> EncodedPoint

Serialize this VerifyingKey as a SEC1 EncodedPoint, optionally applying point compression.

pub fn as_affine(&self) -> &AffinePoint

Borrow the inner AffinePoint for this public key.

Trait Implementations

impl Clone for VerifyingKey

fn clone(&self) -> VerifyingKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<&SigningKey> for VerifyingKey

fn from(signing_key: &SigningKey) -> VerifyingKey
