Interface Signer

Minimal synchronous signer interface.

Consumers that only need ECDSA signing can depend on this rather than the full UniversalSigner.

interface Signer {
    network?: Network;
    publicKey: PublicKey;
    sign(hash: MessageHash, lowR?: boolean): Signature;
    signSchnorr?(hash: MessageHash): SchnorrSignature;
}

Properties

`Optional` `Readonly`network

network?: Network

Network this signer is bound to, if any.

`Readonly`publicKey

publicKey: PublicKey

SEC1-encoded public key (33 or 65 bytes).

Methods

sign

sign(hash: MessageHash, lowR?: boolean): Signature
Produces a compact ECDSA signature over hash.
Parameters
- hash: MessageHash
  32-byte message digest.
- OptionallowR: boolean
  When true, grinds for a low-R value (smaller DER encoding).
Returns Signature
- Defined in signer.ts:39

`Optional`signSchnorr

signSchnorr?(hash: MessageHash): SchnorrSignature
Produces a BIP-340 Schnorr signature over hash.
Parameters
- hash: MessageHash
  32-byte message digest.
Returns SchnorrSignature
- Defined in signer.ts:44
