Struct secp256k1::key::PublicKey

pub struct PublicKey(_);

A Secp256k1 public key, used for verification of signatures

Implementations

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_vec(
    &self,
    secp: &Secp256k1,
    compressed: bool
) -> ArrayVec<[u8; 72]>

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 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 add_assign(
    &mut self,
    secp: &Secp256k1,
    other: &PublicKey
) -> Result<(), Error>

Adds another point on the curve in place

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

Multiplies this point by secret scalar

Trait Implementations
