Struct PublicKey 

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

A public key (safe to share, serialize, etc.).

Implementations

impl PublicKey

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

Create from raw bytes.

pub fn try_from_slice(slice: &[u8]) -> CryptoResult<Self>

Try to create from a slice.

Errors

Returns CryptoError::InvalidKeyLength if the slice is not exactly 32 bytes.

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

Get the raw bytes.

pub fn key_id(&self) -> [u8; 8]

Get a short key ID (first 8 bytes).

pub fn key_id_hex(&self) -> String

Get the key ID as a hex string.

pub fn to_hex(&self) -> String

Encode as hex string.

pub fn from_hex(s: &str) -> CryptoResult<Self>

Decode from hex string.

Errors

Returns an error if the string is not valid hex or not 32 bytes.

pub fn to_base64(&self) -> String

Encode as base64 string.

pub fn from_base64(s: &str) -> CryptoResult<Self>

Decode from base64 string.

Errors

Returns an error if the string is not valid base64 or not 32 bytes.

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

Verify a signature against this public key.

Errors

Returns CryptoError::SignatureVerificationFailed if verification fails.

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<'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 Display for PublicKey

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

Formats the value using the given formatter.

impl From<[u8; 32]> for PublicKey

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

Converts to this type from the input type.

impl From<PublicKey> for [u8; 32]

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PublicKey

impl Eq for PublicKey
