Struct saito_rust::crypto::PublicKey

#[repr(transparent)]
pub struct PublicKey(_);

A Secp256k1 public key, used for verification of signatures

Implementations

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>(secp: &Secp256k1<C>, sk: &SecretKey) -> PublicKey where
    C: Signing, 

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>(&mut self, secp: &Secp256k1<C>) where
    C: Verification, 

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

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

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

pub fn combine_keys(keys: &[&PublicKey]) -> Result<PublicKey, Error>

Adds the keys in the provided slice together, returning the sum. Returns an error if the result would be the point at infinity, i.e. we are adding a point to its own negation
