Struct Secp256k1PrivateKey 

pub struct Secp256k1PrivateKey { /* private fields */ }

Available on crate feature secp256k1 only.

A Secp256k1 ECDSA private key.

The private key is zeroized when dropped.

Implementations

impl Secp256k1PrivateKey

pub fn generate() -> Self

Generates a new random Secp256k1 private key.

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

Creates a private key from raw bytes.

Errors

Returns AptosError::InvalidPrivateKey if:

• The byte slice length is not exactly 32 bytes
• The bytes do not represent a valid Secp256k1 private key

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

Creates a private key from a hex string.

Errors

Returns AptosError::Hex if the hex string is invalid. Returns AptosError::InvalidPrivateKey if the decoded bytes are not exactly 32 bytes or do not represent a valid Secp256k1 private key.

pub fn from_aip80(s: &str) -> AptosResult<Self>

Creates a private key from AIP-80 format string.

AIP-80 format: secp256k1-priv-0x{hex_bytes}

Errors

Returns an error if the format is invalid or the key bytes are invalid.

pub fn to_bytes(&self) -> [u8; 32]

Returns the private key as bytes.

pub fn to_hex(&self) -> String

Returns the private key as a hex string.

pub fn to_aip80(&self) -> String

Returns the private key in AIP-80 format.

AIP-80 format: secp256k1-priv-0x{hex_bytes}

pub fn public_key(&self) -> Secp256k1PublicKey

Returns the corresponding public key.

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

Signs a message (pre-hashed with SHA256) and returns a low-S signature.

The k256 crate produces low-S signatures by default. An additional normalization step is included as defense-in-depth to guarantee Aptos on-chain compatibility.

pub fn sign_prehashed(&self, hash: &[u8; 32]) -> Secp256k1Signature

Signs a pre-hashed message directly and returns a low-S signature.

The k256 crate produces low-S signatures by default. An additional normalization step is included as defense-in-depth.

Trait Implementations

impl Clone for Secp256k1PrivateKey

fn clone(&self) -> Secp256k1PrivateKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Secp256k1PrivateKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Signer for Secp256k1PrivateKey

type Signature = Secp256k1Signature

The signature type produced by this signer.

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

Signs the given message and returns a signature.

fn public_key(&self) -> Secp256k1PublicKey

Returns the public key corresponding to this signer.

impl Zeroize for Secp256k1PrivateKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
