Module win_crypto_ng::asymmetric::signature

source ·
Expand description

Digital signature facilities.

A scheme to verify the authenticity of digital messages or documents using asymmetric cryptography.

Example

use win_crypto_ng::asymmetric::signature::{Signer, Verifier, SignaturePadding};
use win_crypto_ng::asymmetric::{AsymmetricKey, Rsa};
use win_crypto_ng::hash::HashAlgorithmId;

let key = AsymmetricKey::builder(Rsa).key_bits(1024).build().unwrap();

let data: Vec<u8> = (0..32).collect();
let padding = SignaturePadding::pkcs1(HashAlgorithmId::Sha256);
let signature = key.sign(&*data, Some(padding)).expect("Signing to succeed");

key.verify(&data, &signature, Some(padding)).expect("Signature to be valid");

key.verify(&[0xDE, 0xAD], &signature, Some(padding)).expect_err("Bad digest");
key.verify(&data, &[0xDE, 0xAD], Some(padding)).expect_err("Bad signature");

Structs
