Struct PublicKey

#[repr(C)]
pub struct PublicKey(pub [u8; 32]);

The public half of a Keypair.

Tuple Fields

0: [u8; 32]

Implementations

impl PublicKey

pub const SIZE: usize = 32usize

Size of a public key, in bytes (== 32).

pub fn from_slice(s: &[u8]) -> Option<PublicKey>

Deserialize a public key from a byte slice. The slice length must be 32.

pub fn from_base64(s: &str) -> Option<PublicKey>

Deserialize from the base-64 representation. Ignores optional leading ‘@’ sigil and ‘.ed25519’ suffix.

Example

use ssb_crypto::PublicKey;
let author = "@H2qXeS5sOKUqaGNFgRJ6qR48+lAeP0C9lq9IVlQMotc=.ed25519";
let pk = PublicKey::from_base64(author).unwrap();

pub fn as_base64(&self) -> String

Does not include “.ed25519” suffix or a prefix sigil.

Example

let s = "H2qXeS5sOKUqaGNFgRJ6qR48+lAeP0C9lq9IVlQMotc=";
let pk = ssb_crypto::PublicKey::from_base64(s).unwrap();
assert_eq!(pk.as_base64(), s);

pub fn verify(&self, sig: &Signature, b: &[u8]) -> bool

Verify that a signature was generated by this key’s secret half for the given bytes.

Trait Implementations

impl AsBytes for PublicKey

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

Get the bytes of this value.

fn as_bytes_mut(&mut self) -> &mut [u8]

where Self: FromBytes,

Get the bytes of this value mutably.

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<(), Error>

Formats the value using the given formatter.

impl Hash for PublicKey

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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.
