CustomNonce allows users to pass in a custom set of auxData that's used as input randomness to generate the nonce used during signing.

FastSign forces signing to skip the extra verification step at the end.

NewSignature instantiates a new signature given some r and s values.

ParsePubKey parses a public key for a koblitz curve from a bytestring into a btcec.Publickey, verifying that it is valid.

ParseSignature parses a signature according to the BIP-340 specification and enforces the following additional restrictions specific to secp256k1: - The r component must be in the valid range for secp256k1 field elements - The s component must be in the valid range for secp256k1 scalars.

SerializePubKey serializes a public key as specified by BIP 340.

Sign generates an BIP-340 signature over the secp256k1 curve for the provided hash (which should be the result of hashing a larger message) using the given private key.

These constants define the lengths of serialized public keys.

SignatureSize is the size of an encoded Schnorr signature.

Signature is a type representing a Schnorr signature.

Error identifies an error related to a schnorr signature.

ErrorKind identifies a kind of error.

SignOption is a functional option argument that allows callers to modify the way we generate BIP-340 schnorr signatures.
