Struct fog_pack::crypto::Signature

pub struct Signature { /* fields omitted */ }

Signatures are used to authenticate a piece of data based on its hash.

One can be generated for a given Hash using a the sign function on a Vault. The versions of the underlying key and hash are stored, along with the identifying information of the key used.

It can be verified by providing the hash of the data. The signing identity can be determined from checking against the Identity returned by signed_by.

Implementations

impl Signature

pub fn get_hash_version(&self) -> u8

Version of the Hash used in signature computation.

pub fn signed_by(&self) -> &Identity

Retrieve the Identity of the signer.

pub fn verify(&self, hash: &Hash) -> bool

Verify the signature is authentic.

pub fn len(&self) -> usize

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

Write the signature data out to a byte stream.

pub fn decode(buf: &mut &[u8]) -> Result<Signature, CryptoError>

Read the signature data out of a byte stream.

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: &Signature) -> bool

This method tests for !=.
