Struct Secp256k1Account 

pub struct Secp256k1Account { /* private fields */ }

Available on crate feature secp256k1 only.

A Secp256k1 ECDSA account for signing transactions.

This account type uses the same elliptic curve as Bitcoin and Ethereum.

Example

use aptos_sdk::account::Secp256k1Account;

let account = Secp256k1Account::generate();
println!("Address: {}", account.address());

Implementations

impl Secp256k1Account

pub fn generate() -> Self

Generates a new random Secp256k1 account.

pub fn from_private_key(private_key: Secp256k1PrivateKey) -> Self

Creates an account from a private key.

pub fn from_private_key_bytes(bytes: &[u8]) -> AptosResult<Self>

Creates an account from private key bytes.

Errors

Returns an error if the bytes are not a valid Secp256k1 private key (must be exactly 32 bytes and a valid curve point).

pub fn from_private_key_hex(hex_str: &str) -> AptosResult<Self>

Creates an account from a private key hex string.

Errors

This function will return an error if:

• The hex string is invalid or cannot be decoded
• The decoded bytes are not a valid Secp256k1 private key

pub fn address(&self) -> AccountAddress

Returns the account address.

pub fn public_key(&self) -> &Secp256k1PublicKey

Returns the public key.

pub fn private_key(&self) -> &Secp256k1PrivateKey

Returns a reference to the private key.

pub fn sign_message(&self, message: &[u8]) -> Secp256k1Signature

Signs a message and returns the Secp256k1 signature.
