Struct WalletSigner

pub struct WalletSigner<D: PrehashSigner<Signature>> { /* private fields */ }

A Neo private-public key pair which can be used for signing messages.

Examples

Signing and Verifying a message

The wallet can be used to produce ECDSA p256::NistP256 objects, which can be then verified.

// WalletSigner is used for transaction signing
// Example usage is demonstrated in integration tests

Implementations

impl WalletSigner<Signer<NistP256>>

pub fn connect( connector: Connector, credentials: Credentials, id: Id, ) -> Result<Self, WalletError>

Connects to a yubi key’s ECDSA account at the provided id

pub fn new( connector: Connector, credentials: Credentials, id: Id, label: Label, domain: Domain, ) -> Result<Self, WalletError>

Creates a new random ECDSA keypair on the yubi at the provided id

pub fn from_key( connector: Connector, credentials: Credentials, id: Id, label: Label, domain: Domain, key: impl Into<Vec<u8>>, ) -> Result<Self, WalletError>

Uploads the provided keypair on the yubi at the provided id

impl<D: PrehashSigner<Signature>> WalletSigner<D>

pub fn new_with_signer(signer: D, address: Address) -> Self

Creates a new WalletSigner instance using an external Signer and associated Ethereum address.

Arguments

• signer - An implementation of the PrehashSigner trait capable of signing messages.
• address - The Ethereum address associated with the signer’s public key.

Returns

A new WalletSigner instance.

impl<D: Sync + Send + PrehashSigner<Signature>> WalletSigner<D>

pub fn sign_hash(&self, hash: H256) -> Result<Signature, WalletError>

Signs a given hash directly, without performing any additional hashing.

Arguments

• hash - A H256 hash to be signed.

Returns

A Result containing the p256::NistP256 of the hash, or a WalletError on failure.

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

Signs a given message, using the wallet’s private key. The message will be hashed using the Sha256 algorithm before being signed.

Arguments

• message - The message to be signed.

Returns

A Result containing the p256::NistP256 of the message, or a WalletError on failure.

pub fn signer(&self) -> &D

Returns a reference to the wallet’s signer.

Returns

A reference to the D, the signer.
