Struct SigningKey 

pub struct SigningKey { /* private fields */ }

A key that can sign messages.

This bundles together a public key and the ability to sign with the corresponding private key. For in-memory keys, signing is instant. For hardware wallets or KMS, signing may involve async operations.

Example

use near_kit::{InMemorySigner, Signer};

let signer = InMemorySigner::new("alice.testnet", "ed25519:...")?;

let key = signer.key();
println!("Public key: {}", key.public_key());

let signature = key.sign(b"message").await?;

Implementations

impl SigningKey

pub fn new(secret_key: SecretKey) -> Self

Create a new signing key from a secret key.

pub fn public_key(&self) -> &PublicKey

Get the public key.

pub async fn sign(&self, message: &[u8]) -> Result<Signature, SignerError>

Sign a message.

For in-memory keys, this returns immediately. For hardware wallets or KMS, this may involve user confirmation or network requests.

pub async fn sign_nep413( &self, account_id: &AccountId, params: &SignMessageParams, ) -> Result<SignedMessage, SignerError>

Sign a NEP-413 message for off-chain authentication.

Example

use near_kit::{InMemorySigner, Signer, nep413};

let signer = InMemorySigner::new("alice.testnet", "ed25519:...")?;
let key = signer.key();

let params = nep413::SignMessageParams {
    message: "Login to MyApp".to_string(),
    recipient: "myapp.com".to_string(),
    nonce: nep413::generate_nonce(),
    callback_url: None,
    state: None,
};

let signed = key.sign_nep413(&signer.account_id(), &params).await?;
