Struct libsecp256k1_rs::PublicKey

pub struct PublicKey(_);

Public key on a secp256k1 curve.

Methods

impl PublicKey

pub fn from_secret_key(seckey: &SecretKey) -> PublicKey

Create a public key from a private key by performing P = k.G

pub fn parse_compressed(p: &[u8; 33]) -> Result<PublicKey, Error>

Create a public key from a compressed public key. Remember that Public keys are just points on the elliptic curve, so you can derive the full point by supplying the x-coordinate and the parity. By convention, compressed public keys hold the parity in the first byte and the x-coordinate in the next 32 bytes.

pub fn parse(p: &[u8; 65]) -> Result<PublicKey, Error>

Create a PublicKey from 65-byte binary representation of a public key. The first byte is a prefix (must be 4,6, or 7). The next 32 bytes represent the x-coordinate; and the last 32 bytes represent thew y-coordinate.

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

Return the 65-bit serialization of the public key. The first byte is always 0x04 to represent an uncompressed public key.

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

Return the 33-bit serialization of the compressed public key.
