Struct secp256k1::key::PublicKey

pub struct PublicKey(_);

A Secp256k1 public key, used for verification of signatures

Methods

impl PublicKey

pub fn new() -> PublicKey

Creates a new zeroed out public key

pub fn is_valid(&self) -> bool

Determines whether a pubkey is valid

pub fn as_ptr(&self) -> *const PublicKey

Obtains a raw pointer suitable for use with FFI functions

pub fn from_secret_key(
    secp: &Secp256k1,
    sk: &SecretKey
) -> Result<PublicKey, Error>

Creates a new public key from a secret key.

pub fn from_slice(secp: &Secp256k1, data: &[u8]) -> Result<PublicKey, Error>

Creates a public key directly from a slice

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

Serialize the key as a byte-encoded pair of values. In compressed form the y-coordinate is represented by only a single bit, as x determines it up to one bit.

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

Serialize the key as a byte-encoded pair of values, in uncompressed form

pub fn add_exp_assign(
    &mut self,
    secp: &Secp256k1,
    other: &SecretKey
) -> Result<(), Error>

Adds the pk corresponding to other to the pk self in place

pub fn mul_assign(
    &mut self,
    secp: &Secp256k1,
    other: &SecretKey
) -> Result<(), Error>

Muliplies the pk self in place by the scalar other

pub fn combine(
    &self,
    secp: &Secp256k1,
    other: &PublicKey
) -> Result<PublicKey, Error>

Adds a second key to this one, returning the sum. Returns an error if the result would be the point at infinity, i.e. we are adding this point to its own negation

Trait Implementations

impl Copy for PublicKey
