Implementations

impl ECPrivateKey

pub fn new() -> Self

Creates a new random ECDSA private key using the given random number generator.

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

Returns the ECDSA private key as an array of bytes.

pub const fn from_data(data: [u8; 32]) -> Self

Restores an ECDSA private key from an array of bytes.

pub fn from_data_ref(data: impl AsRef<[u8]>) -> Result<Self>

Restores an ECDSA private key from a reference to an array of bytes.

pub fn derive_from_key_material(key_material: impl AsRef<[u8]>) -> Self

impl ECPrivateKey

pub fn schnorr_public_key(&self) -> SchnorrPublicKey

Derives the Schnorr public key from this ECDSA private key.

pub fn ecdsa_sign(&self, message: impl AsRef<[u8]>) -> [u8; 64]

ECDSA signs the given message using this ECDSA private key.

pub fn schnorr_sign_using( &self, message: impl AsRef<[u8]>, rng: &mut dyn RandomNumberGenerator, ) -> [u8; 64]

Schnorr signs the given message using this ECDSA private key, the given tag, and the given random number generator.

Trait Implementations

impl AsRef<[u8]> for ECPrivateKey

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl CBORTagged for ECPrivateKey

fn cbor_tags() -> Vec<Tag>

The CBOR tags assocated with this type. If more than one tag is present, they are considered equivalent for reading, but only the first one is used for writing.

impl CBORTaggedEncodable for ECPrivateKey

fn untagged_cbor(&self) -> CBOR

Returns the untagged CBOR encoding of this instance.

fn tagged_cbor(&self) -> CBOR

Returns the tagged CBOR encoding of this instance.

fn tagged_cbor_data(&self) -> Vec<u8>

Returns the tagged value in CBOR binary representation.

impl Clone for ECPrivateKey

fn clone(&self) -> ECPrivateKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ECPrivateKey

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

Formats the value using the given formatter.

impl Default for ECPrivateKey

fn default() -> Self

Returns the “default value” for a type.

impl Display for ECPrivateKey

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

Formats the value using the given formatter.

impl ECKey for ECPrivateKey

fn public_key(&self) -> ECPublicKey

impl ECKeyBase for ECPrivateKey

const KEY_SIZE: usize = 32usize

fn from_data_ref(data: impl AsRef<[u8]>) -> Result<Self>

where Self: Sized,

fn data(&self) -> &[u8]

fn hex(&self) -> String

fn from_hex(hex: impl AsRef<str>) -> Result<Self>

impl<'a> From<&'a ECPrivateKey> for &'a [u8]

fn from(value: &'a ECPrivateKey) -> Self

Converts to this type from the input type.

impl<'a> From<&'a ECPrivateKey> for &'a [u8; 32]

fn from(value: &'a ECPrivateKey) -> Self

Converts to this type from the input type.

impl From<[u8; 32]> for ECPrivateKey

fn from(data: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<ECPrivateKey> for CBOR

fn from(value: ECPrivateKey) -> Self

Converts to this type from the input type.

impl Hash for ECPrivateKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ECPrivateKey

fn eq(&self, other: &ECPrivateKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
