Struct Secp256r1Account 

pub struct Secp256r1Account { /* private fields */ }

👎Deprecated since 0.5.0:

Use WebAuthnAccount for on-chain transaction signing. Bare secp256r1 signatures are not accepted by Aptos validators (the on-chain AnySignature variant 2 is WebAuthn, not Secp256r1Ecdsa). This type is retained for off-chain use only.

Available on crate feature secp256r1 only.

A Secp256r1 (P-256) ECDSA account.

⚠️ Deprecated for on-chain transaction signing

On current Aptos networks the on-chain AnySignature variant at index 2 is WebAuthn, not bare secp256r1 ECDSA. Transactions signed by this account type are rejected by every Aptos validator. Use WebAuthnAccount instead – it reuses the same key material and produces the correct WebAuthn-envelope wire format.

This type is still useful for off-chain P-256 use (sign / verify of arbitrary bytes, key import/export, key-derivation testing) and for constructing MultiKeyAccount public-key material.

Example

use aptos_sdk::account::Secp256r1Account;

// For off-chain signing only -- this account cannot submit
// transactions to a live Aptos network. Use `WebAuthnAccount` for that.
let account = Secp256r1Account::generate();
println!("Address: {}", account.address());

Implementations

impl Secp256r1Account

pub fn generate() -> Self

Generates a new random Secp256r1 account.

pub fn from_private_key(private_key: Secp256r1PrivateKey) -> 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 Secp256r1 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 Secp256r1 private key

pub fn address(&self) -> AccountAddress

Returns the account address.

pub fn public_key(&self) -> &Secp256r1PublicKey

Returns the public key.

pub fn private_key(&self) -> &Secp256r1PrivateKey

Returns a reference to the private key.

pub fn sign_message(&self, message: &[u8]) -> Secp256r1Signature

Signs a message and returns the Secp256r1 signature.
