Struct Signer

pub struct Signer { /* private fields */ }

An object that can generate signatures

Examples

let mut rng = botan::RandomNumberGenerator::new_system().unwrap();
let rsa = botan::Privkey::create("RSA", "2048", &mut rng).unwrap();
let mut signer = botan::Signer::new(&rsa, "PKCS1v15(SHA-256)").unwrap();
signer.update(&[1,2,3]).unwrap();
let signature = signer.finish(&mut rng).unwrap();

Implementations

impl Signer

pub fn new(key: &Privkey, padding: &str) -> Result<Signer>

Create a new signature operator

pub fn update(&mut self, data: &[u8]) -> Result<()>

Add more bytes of the message that will be signed

pub fn finish(&mut self, rng: &mut RandomNumberGenerator) -> Result<Vec<u8>>

Complete and return the signature
