Overview

For BIP-340 Schnorr signature verification, use the xonly property of this key. The full P256K.Schnorr.PublicKey is provided for contexts that require the complete curve point, such as key aggregation (aggregate(_:)) or BIP-341 Taproot key-path spending.

Topics

Construction

init(xonlyKey: P256K.Schnorr.XonlyKey)
Creates a compressed secp256k1 public key from an x-only key by prepending the 0x02 (even-Y) or 0x03 (odd-Y) parity prefix.
init<D>(dataRepresentation: D, format: P256K.Format) throws
Creates a secp256k1 Schnorr public key from serialized bytes.

Serialized Forms

var dataRepresentation: Data
The serialized public key bytes as Data, in the key’s format.
var format: P256K.Format
The serialization format of this public key: .compressed (33 bytes) or .uncompressed (65 bytes).
var xonly: P256K.Schnorr.XonlyKey
The 32-byte x-only public key (X coordinate only) derived from this key for use in BIP-340 Schnorr signature verification.
