Struct ssb_crypto::PublicKey

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

The public half of a Keypair.

Implementations

impl PublicKey

pub const SIZE: usize

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

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

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

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

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.

impl Ord for PublicKey

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<PublicKey> for PublicKey

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

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &PublicKey) -> bool

This method tests for !=.

impl PartialOrd<PublicKey> for PublicKey

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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