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 from_hex(h: &str) -> Result<PublicKey, Error>

Generate a public key from hex The expected format is a tag (0x04, 0x06 or 0x07) for uncompressed keys, 0x02, 0x03 for compressed keys followed by 32 or 64 bytes, depending on whether the key is compressed or not

pub fn to_hex(&self, compressed: bool) -> String

Return the hexadecimal representation of the public key

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.
