Struct PublicKey 

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

Public key for peer identity, key sharing, and update provenance

A thin wrapper around Iroh’s PublicKey, representing the public part of an Ed25519 keypair. This key serves multiple purposes:

• Peer Identity: Uniquely identifies a peer in the network (equivalent to Iroh’s NodeId)
• Key Sharing: Used in ECDH key exchange (after conversion to X25519)
• Access Control: Listed in bucket shares to grant access

Examples

let secret_key = SecretKey::generate();
let public_key = secret_key.public();

// Serialize to hex for storage/transmission
let hex = public_key.to_hex();
let recovered = PublicKey::from_hex(&hex)?;

Implementations

impl PublicKey

pub fn from_hex(hex: &str) -> Result<Self, KeyError>

Parse a public key from a hexadecimal string

Accepts both plain hex and “0x”-prefixed hex strings.

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

Convert public key to raw bytes

pub fn to_hex(&self) -> String

Convert public key to hexadecimal string

Methods from Deref<Target = PPublicKey>

pub const LENGTH: usize = 32usize

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

Get this public key as a byte array.

pub fn public(&self) -> VerifyingKey

Returns the VerifyingKey for this PublicKey.

pub fn verify(&self, message: &[u8], signature: &Signature) -> Result<(), Error>

Verify a signature on a message with this secret key’s public key.

Return

Returns Ok(()) if the signature is valid, and Err otherwise.

pub fn fmt_short(&self) -> impl Display + 'static

Convert to a hex string limited to the first 5 bytes for a friendly string representation of the key.

Trait Implementations

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 Deref for PublicKey

type Target = PublicKey

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

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

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 From<PublicKey> for PublicKey

fn from(key: PPublicKey) -> Self

Converts to this type from the input type.

impl From<PublicKey> for PublicKey

fn from(key: PublicKey) -> Self

Converts to this type from the input type.

impl Hash for PublicKey

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 Ord for PublicKey

fn cmp(&self, other: &PublicKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for PublicKey

fn partial_cmp(&self, other: &PublicKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PublicKey

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

type Error = KeyError

The type returned in the event of a conversion error.

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

Performs the conversion.
