Trait Signer 

pub trait Signer<H: Hashable> {
    // Required methods
    fn sign(&mut self, kp: &Keypair, input: &H, packed: bool) -> Signature;
    fn verify(&mut self, sig: &Signature, pub_key: &PubKey, input: &H) -> bool;
}

Interface for signed objects

Signer interface for signing [Hashable] inputs and verifying Signatures using Keypairs and PubKeys

Required Methods

fn sign(&mut self, kp: &Keypair, input: &H, packed: bool) -> Signature

Sign input (see [Hashable]) using keypair kp and return the corresponding signature.

Parameters

• kp - The keypair to use for signing
• input - The message to sign (must implement [Hashable])
• packed - Controls nonce derivation method:
  • true: Use OCaml/TypeScript compatible nonce derivation with field packing
  • false: Use standard Rust nonce derivation

Returns

A Signature over the input message.

Compatibility

Use packed: true when compatibility with OCaml and TypeScript implementations is required. Use packed: false for standard Rust-only usage.

Note: The standard nonce derivation (packed: false) will be deprecated in future versions. Use packed: true for new code to ensure forward compatibility.

fn verify(&mut self, sig: &Signature, pub_key: &PubKey, input: &H) -> bool

Verify that the signature sig on input (see [Hashable]) is signed with the secret key corresponding to pub_key. Return true if the signature is valid and false otherwise.
