Struct cosmian_crypto_core::Curve25519Secret

pub struct Curve25519Secret(/* private fields */);

Secret from which the private keys are derived

Implementations

impl Curve25519Secret

Facades

Facades are used to hide the underlying types and provide a more user friendly interface to the user.

pub fn new<R: CryptoRngCore>(rng: &mut R) -> Self

Generate a random private key

This is a facade to RandomFixedSizeCBytes::new

pub fn as_bytes(&self) -> &[u8]

Get the underlying bytes slice of the private key

This is a facade to RandomFixedSizeCBytes::as_bytes

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

Serialize the PrivateKey as a non zero scalar

This is a facade to <Self as FixedSizeCBytes>::to_bytes

pub fn try_from_bytes(bytes: [u8; 32]) -> Result<Self, CryptoCoreError>

Deserialize the PrivateKey from a non zero scalar

This is a facade to <Self as FixedSizeCBytes<CURVE_25519_SECRET_LENGTH>>::try_from_bytes

impl Curve25519Secret

pub fn from_ed25519_private_key(sk: &Ed25519PrivateKey) -> Self

Convert the ED25519 private key to an X25519 private key

This method is useful when an Ed25519 public key has been converted to an X25519 public key. It will generate the private key that corresponds to the generated X25519 public key from the original private key.

See [X25519PublicKey::from_ed25519_public_key] for more details.

Trait Implementations

impl Clone for Curve25519Secret

fn drop(&mut self)

Executes the destructor for this type.

impl FixedSizeCBytes<{ CURVE_25519_SECRET_LENGTH }> for Curve25519Secret

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

Converts the given key into an array of LENGTH bytes.

fn try_from_bytes(bytes: [u8; 32]) -> Result<Self, CryptoCoreError>

Tries to create a key from the given array of bytes into a key.

const LENGTH: usize = LENGTH

Key length.

fn try_from_slice(slice: &[u8]) -> Result<Self, CryptoCoreError>

Tries to create a key from the given slice of bytes into a key.

impl From<&Curve25519Secret> for X25519PrivateKey

fn from(sk: &Ed25519PrivateKey) -> Self

Converts to this type from the input type.

impl From<&Curve25519Secret> for Ed25519PublicKey

fn from(sk: &Ed25519PrivateKey) -> Self

Converts to this type from the input type.

impl From<&Curve25519Secret> for X25519CurvePoint

fn from(sk: &X25519PrivateKey) -> Self

impl Hash for Curve25519Secret

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 Curve25519Secret

fn eq(&self, other: &Curve25519Secret) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl RandomFixedSizeCBytes<{ CURVE_25519_SECRET_LENGTH }> for Curve25519Secret

fn new<R: CryptoRngCore>(rng: &mut R) -> Self

Generates a new random array of LENGTH bytes

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

Key Serialization framework

type Error = CryptoCoreError

Error type returned by the serialization.

fn length(&self) -> usize

Retrieves the length of the serialized object if it can be known.

fn write(&self, ser: &mut Serializer) -> Result<usize, Self::Error>

Writes to the given Serializer.

fn read(de: &mut Deserializer<'_>) -> Result<Self, Self::Error>

Reads from the given Deserializer.

fn serialize(&self) -> Result<Zeroizing<Vec<u8>>, Self::Error>
