Enum EcdsaPublicKey 

pub enum EcdsaPublicKey {
    NistP256(EncodedPoint<U32>),
    NistP384(EncodedPoint<U48>),
    NistP521(EncodedPoint<U66>),
}

Available on crate feature ecdsa only.

Elliptic Curve Digital Signature Algorithm (ECDSA) public key.

Public keys are represented as sec1::EncodedPoint and require the sec1 feature of this crate is enabled (which it is by default).

Described in FIPS 186-4.

Variants

NistP256(EncodedPoint<U32>)

NistP384(EncodedPoint<U48>)

NIST P-384 ECDSA public key.

NistP521(EncodedPoint<U66>)

NIST P-521 ECDSA public key.

Converts to this type from the input type.

impl From<EcdsaKeypair> for EcdsaPublicKey

fn from(keypair: EcdsaKeypair) -> EcdsaPublicKey

impl From<EcdsaPublicKey> for KeyData

fn from(public_key: EcdsaPublicKey) -> KeyData

Converts to this type from the input type.

impl From<EcdsaPublicKey> for PublicKey

fn from(public_key: EcdsaPublicKey) -> PublicKey

Converts to this type from the input type.

impl Hash for EcdsaPublicKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl LowerHex for EcdsaPublicKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Ord for EcdsaPublicKey

fn cmp(&self, other: &EcdsaPublicKey) -> Ordering

This method returns an Ordering between self and other.

impl PartialEq for EcdsaPublicKey

fn eq(&self, other: &EcdsaPublicKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
