Struct secp256k1::key::PublicKey

pub struct PublicKey(_);

A Secp256k1 public key, used for verification of signatures

Methods

impl PublicKey

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

Obtains a raw const pointer suitable for use with FFI functions

pub fn as_mut_ptr(&mut self) -> *mut PublicKey

Obtains a raw mutable pointer suitable for use with FFI functions

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

Creates a new public key from a secret key.

pub fn from_slice(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 negate_assign<C: Verification>(&mut self, secp: &Secp256k1<C>)

Negates the pk to the pk self in place Will return an error if the pk would be invalid.

pub fn add_exp_assign<C: Verification>(
    &mut self,
    secp: &Secp256k1<C>,
    other: &[u8]
) -> Result<(), Error>

Adds the pk corresponding to other to the pk self in place Will return an error if the resulting key would be invalid or if the tweak was not a 32-byte length slice.

pub fn mul_assign<C: Verification>(
    &mut self,
    secp: &Secp256k1<C>,
    other: &[u8]
) -> Result<(), Error>

Muliplies the pk self in place by the scalar other Will return an error if the resulting key would be invalid or if the tweak was not a 32-byte length slice.

pub fn combine(&self, 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
