Struct secp256k1::key::PublicKey
[−]
[src]
pub struct PublicKey(_);
A Secp256k1 public key, used for verification of signatures
Methods
impl PublicKey
[src]
fn new() -> PublicKey
Creates a new zeroed out public key
fn is_valid(&self) -> bool
Determines whether a pubkey is valid
fn as_ptr(&self) -> *const PublicKey
Obtains a raw pointer suitable for use with FFI functions
fn from_secret_key(secp: &Secp256k1, sk: &SecretKey) -> Result<PublicKey, Error>
Creates a new public key from a secret key.
fn from_slice(secp: &Secp256k1, data: &[u8]) -> Result<PublicKey, Error>
Creates a public key directly from a slice
fn serialize_vec(
&self,
secp: &Secp256k1,
compressed: bool
) -> ArrayVec<[u8; 72]>
&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.
fn add_exp_assign(
&mut self,
secp: &Secp256k1,
other: &SecretKey
) -> Result<(), Error>
&mut self,
secp: &Secp256k1,
other: &SecretKey
) -> Result<(), Error>
Adds the pk corresponding to other
to the pk self
in place
fn add_assign(
&mut self,
secp: &Secp256k1,
other: &PublicKey
) -> Result<(), Error>
&mut self,
secp: &Secp256k1,
other: &PublicKey
) -> Result<(), Error>
Adds another point on the curve in place
fn mul_assign(
&mut self,
secp: &Secp256k1,
other: &SecretKey
) -> Result<(), Error>
&mut self,
secp: &Secp256k1,
other: &SecretKey
) -> Result<(), Error>
Multiplies this point by secret
scalar
