Struct ursa::bls::MultiSignature

pub struct MultiSignature { /* fields omitted */ }

BLS multi signature.

Implementations

impl MultiSignature

pub fn new(signatures: &[&Signature]) -> UrsaCryptoResult<MultiSignature>

Creates and returns multi signature for provided list of signatures.

Arguments

• signatures - List of signatures

Example

use ursa::bls::*;
let sign_key1 = SignKey::new(None).unwrap();
let sign_key2 = SignKey::new(None).unwrap();

let message = vec![1, 2, 3, 4, 5];

let signature1 = Bls::sign(&message, &sign_key1).unwrap();
let signature2 = Bls::sign(&message, &sign_key2).unwrap();

let signatures = vec![
   &signature1,
   &signature2
];

MultiSignature::new(&signatures).unwrap();

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

Returns BLS multi signature bytes representation.

Example

use ursa::bls::{SignKey, Bls, MultiSignature};
let message = vec![1, 2, 3, 4, 5];
let sign_key1 = SignKey::new(None).unwrap();
let sign_key2 = SignKey::new(None).unwrap();
let signature1 = Bls::sign(&message, &sign_key1).unwrap();
let signature2 = Bls::sign(&message, &sign_key2).unwrap();
let signatures = vec![&signature1, &signature2];
let multi_signature = MultiSignature::new(&signatures).unwrap();
let bytes = multi_signature.as_bytes();

pub fn from_bytes(bytes: &[u8]) -> UrsaCryptoResult<MultiSignature>

Creates and returns BLS multi signature from bytes representation.

Example

use ursa::bls::{SignKey, Bls, MultiSignature};
let message = vec![1, 2, 3, 4, 5];
let sign_key1 = SignKey::new(None).unwrap();
let sign_key2 = SignKey::new(None).unwrap();
let signature1 = Bls::sign(&message, &sign_key1).unwrap();
let signature2 = Bls::sign(&message, &sign_key2).unwrap();
let signatures = vec![&signature1, &signature2];
let multi_signature = MultiSignature::new(&signatures).unwrap();
let bytes = multi_signature.as_bytes();
let multi_signature2 = MultiSignature::from_bytes(bytes).unwrap();
