Enum PublicKey 

#[non_exhaustive]
pub enum PublicKey {
    Ed25519(VerifyingKey),
}

Algorithm-agnostic public key for signature verification.

Wraps algorithm-specific verifying key types in a single enum, enabling crypto-agility while maintaining zero-cost dispatch for the common Ed25519 case.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ed25519(VerifyingKey)

Ed25519 public key (32 bytes)

Implementations

impl PublicKey

pub fn verify(&self, data: &[u8], signature: &[u8]) -> Result<(), AuthError>

Verify a signature over the given data.

Returns Ok(()) if the signature is valid, or Err if verification fails for any reason (malformed signature, wrong key, etc.).

pub fn to_prefixed_string(&self) -> String

Format the public key as a prefixed string (e.g. "ed25519:base64...").

pub fn from_prefixed_string(s: &str) -> Result<Self, AuthError>

Parse a public key from a prefixed string (e.g. "ed25519:base64...").

pub fn random() -> Self

Generate a random public key.

Creates a fresh Ed25519 keypair and returns only the public key, discarding the private key.

pub fn algorithm(&self) -> &'static str

Get the algorithm name for this 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<'de> Deserialize<'de> for PublicKey

Deserializes from the prefixed string format (e.g. "ed25519:base64...").

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

Deserialize this value from the given Serde deserializer.

impl Display for PublicKey

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

Formats the value using the given formatter.

impl From<&PublicKey> for PeerId

fn from(pk: &PublicKey) -> Self

Converts to this type from the input type.

impl From<PublicKey> for PeerId

fn from(pk: 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 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 Serialize for PublicKey

Serializes as the prefixed string format (e.g. "ed25519:base64...").

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

Serialize this value into the given Serde serializer.
