Struct AdaptorSigner 

pub struct AdaptorSigner { /* private fields */ }

Signer for adaptor signatures

Implementations

impl AdaptorSigner

pub fn new() -> Self

Create a new random signer

pub fn from_bytes(bytes: &[u8; 32]) -> AdaptorResult<Self>

Create from secret key bytes

pub fn public_key(&self) -> AdaptorPublicKey

Get the public key

pub fn to_bytes(&self) -> [u8; 32]

Export secret key to bytes

pub fn create_pre_signature_with_secret( &self, message: &[u8], adaptor_secret: &AdaptorSecret, ) -> AdaptorResult<PreSignature>

Create a pre-signature (locked to adaptor point)

This creates a signature that can only be completed by someone who knows the adaptor secret t corresponding to the adaptor point T = t*G.

The pre-signature is (R’, s’) where R’ = R + T and s’ = k + c*x (standard Schnorr). To complete, the holder of t computes s = s’ + t.

pub fn create_pre_signature( &self, message: &[u8], adaptor: &AdaptorPoint, ) -> AdaptorResult<PreSignature>

Create a pre-signature (for compatibility - same as create_pre_signature_with_secret)

Note: This version requires the adaptor point but internally needs the secret. This is a simplified API. For proper adaptor signatures where the signer doesn’t know the adaptor secret, see ECDSA adaptor signatures.
