Struct PublicKey 

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

A public key for asymmetric encryption using X25519

This key is used for encrypting messages and can be shared publicly. It is derived from the corresponding secret key using the X25519 elliptic curve.

Properties

• Size: 32 bytes (256 bits)
• Based on the X25519 elliptic curve
• Can be safely shared with anyone
• Used to encrypt messages that can only be decrypted with the corresponding secret key

Implementations

impl PublicKey

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

Generate a new public key from bytes

Arguments

• bytes - Byte slice of exactly PUBLICKEYBYTES length

Returns

• Result<Self> - A new public key or an error if the input is invalid

pub const fn from_bytes_exact(bytes: [u8; 32]) -> Self

Create a public key from a fixed-size bytes

Arguments

• bytes - Byte array of exactly PUBLICKEYBYTES length

Returns

• Self - A new public key

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

Get a reference to the underlying bytes

Returns

• &[u8; PUBLICKEYBYTES] - Reference to the public key bytes

Trait Implementations

impl AsRef<[u8]> for PublicKey

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

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

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a duplicate 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 Display for PublicKey

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

Formats the value using the given formatter.

impl Eq for PublicKey

impl From<PublicKey> for [u8; 32]

fn from(key: PublicKey) -> [u8; 32]

Converts to this type from the input type.

impl From<[u8; 32]> for PublicKey

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

Converts to this type from the input type.

impl PartialEq for PublicKey

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

impl StructuralPartialEq for PublicKey

impl TryFrom<&[u8]> for PublicKey

type Error = SodiumError

The type returned in the event of a conversion error.

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

Performs the conversion.
