Struct orion::hazardous::ecc::x25519::PublicKey

pub struct PublicKey { /* private fields */ }

A type that represents a PublicKey that X25519 uses.

This type holds a field element and is used internally as the u-coordinate. As the RFC mandates, the most significant bit of the last byte is masked.

Errors:

An error will be returned if:

• slice is not 32 bytes.

Implementations

impl PublicKey

pub fn from_slice(slice: &[u8]) -> Result<Self, UnknownCryptoError>

Construct from a given byte slice.

pub fn len(&self) -> usize

Return the length of the object.

pub fn is_empty(&self) -> bool

Return true if this object does not hold any data, false otherwise.

NOTE: This method should always return false, since there shouldn’t be a way to create an empty instance of this object.

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

Convert this PublicKey to its byte-representation.

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PublicKey

Available on crate feature serde only.

This type tries to deserialize as a Vec<u8> would. If it succeeds, the digest will be built using Self::from_slice.

Note that this allocates once to store the referenced bytes on the heap.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<[u8; 32]> for PublicKey

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

Converts to this type from the input type.

impl PartialEq<&[u8]> for PublicKey

fn eq(&self, other: &&[u8]) -> 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 PartialEq<PublicKey> for PublicKey

fn eq(&self, other: &PublicKey) -> 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 Serialize for PublicKey

Available on crate feature serde only.

This type tries to serialize as a &[u8] would. Note that the serialized type likely does not have the same protections that Orion provides, such as constant-time operations. A good rule of thumb is to only serialize these types for storage. Don’t operate on the serialized types.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for PublicKey

Delegates to from_slice implementation

type Error = UnknownCryptoError

The type returned in the event of a conversion error.

fn try_from(slice: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&PrivateKey> for PublicKey

type Error = UnknownCryptoError

The type returned in the event of a conversion error.

fn try_from(private_key: &PrivateKey) -> Result<Self, Self::Error>

Performs the conversion.
