Struct fog_crypto::identity::Signature

pub struct Signature { /* private fields */ }

An annotated cryptographic signature.

Includes the version of hash that was signed, the Identity of the signer, and the signature itself. These are always encoded together to make it easier to verify signatures appended to a chunk of data.

A signature can be constructed in one of two ways: calling sign(...) on an IdentityKey, or by verifying an UnverifiedSignature.

The byte encoding is specifically:

1. The Hash version byte
2. The encoded signing Identity
3. The cryptographic signature’s raw bytes

Implementations

impl Signature

pub fn hash_version(&self) -> u8

The version of the Hash used in signature computation.

pub fn signer(&self) -> &Identity

The public Identity of the IdentityKey that created this signature.

pub fn encode_vec(&self, buf: &mut Vec<u8>)

Encode the signature onto a Vec<u8>. Adds the hash version, signing identity, and signature bytes.

pub fn size(&self) -> usize

The length of the signature, in bytes, when encoded.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl PartialEq<Signature> for Signature

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
