Struct PublicKey 

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

Represents a secp256k1 public key.

The key is internally represented using an AffinePoint and the compressed encoding of it.

The AsRef implementation will always return the compressed representation. However, the TryFrom byte slice accepts any representation.

Implementations

impl PublicKey

pub const SIZE_COMPRESSED: usize = 33usize

Size of the compressed public key in bytes

pub const SIZE_UNCOMPRESSED: usize = 65usize

Size of the uncompressed public key in bytes

pub const SIZE_UNCOMPRESSED_PLAIN: usize = 64usize

pub fn from_privkey(private_key: &[u8]) -> Result<PublicKey>

Computes the public key from the given private_key.

The private key must be a big-endian encoding of a non-zero scalar in the field of the secp256k1 curve.

pub fn to_address(&self) -> Address

Converts the public key to an Ethereum address

pub fn to_uncompressed_bytes(&self) -> Box<[u8]>

Serializes the public key to a binary uncompressed form.

pub fn to_uncompressed_hex(&self) -> String

Serializes the public key to a binary uncompressed form and converts it to hexadecimal string representation.

Trait Implementations

impl AsRef<[u8]> for PublicKey

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<Address> for PublicKey

fn as_ref(&self) -> &Address

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<NonIdentity<AffinePoint>> for PublicKey

fn as_ref(&self) -> &NonIdentity<AffinePoint>

Converts this type into a shared reference of the (usually inferred) input type.

impl BytesRepresentable for PublicKey

const SIZE: usize = 33usize

Size of the encoded byte array.

fn into_boxed(self) -> Box<[u8]>

Convenience function to copy this type’s binary representation into a Box.

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl Display for PublicKey

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

Formats the value using the given formatter.

impl<'a> From<&'a PublicKey> for &'a GenericArray<u8, U33>

fn from(value: &'a PublicKey) -> &'a GenericArray<u8, U33>

Converts to this type from the input type.

impl From<&PublicKey> for ProjectivePoint

fn from(value: &PublicKey) -> Self

Converts to this type from the input type.

impl From<NonIdentity<AffinePoint>> for PublicKey

fn from(value: NonIdentity<AffinePoint>) -> Self

Converts to this type from the input type.

impl From<PublicKey> for NonIdentity<AffinePoint>

fn from(value: PublicKey) -> Self

Converts to this type from the input type.

impl Hash for PublicKey

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PublicKey

fn eq(&self, other: &Self) -> 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.

impl Randomizable for PublicKey

fn random() -> Self

Generates a new random public key. Because the corresponding private key is discarded, this might be useful only for testing purposes.

impl TryFrom<&[u8]> for PublicKey

type Error = GeneralError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<AffinePoint> for PublicKey

type Error = CryptoError

The type returned in the event of a conversion error.

fn try_from(value: AffinePoint) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for PublicKey

impl Eq for PublicKey
