Struct ssri::IntegrityOpts

pub struct IntegrityOpts { /* fields omitted */ }

Builds a new Integrity, allowing multiple algorithms and incremental input.

Examples

use ssri::{Algorithm, IntegrityOpts};
let contents = b"hello world";
let sri = IntegrityOpts::new()
    .algorithm(Algorithm::Sha512)
    .algorithm(Algorithm::Sha1)
    .chain(&contents)
    .result();

Methods

impl IntegrityOpts

pub fn new() -> IntegrityOpts

Creates a new hashing IntegrityOpts.

pub fn algorithm(self, algo: Algorithm) -> Self

Generate a hash for this algorithm. Can be called multiple times to generate an Integrity string with multiple entries.

pub fn input<B: AsRef<[u8]>>(&mut self, input: B)

Add some data to this IntegrityOpts. All internal hashers will be updated for all configured Algorithms.

pub fn chain<B: AsRef<[u8]>>(self, input: B) -> Self

Same as IntegrityOpts::input, but allows chaining.

pub fn reset(&mut self)

Resets internal state for this IntegrityOpts.

pub fn result(self) -> Integrity

Generate a new Integrity from the inputted data and configured algorithms.
