[][src]Trait sequoia_openpgp::crypto::hash::Digest

pub trait Digest: DynClone + Write + Send + Sync {
    fn algo(&self) -> HashAlgorithm;
fn digest_size(&self) -> usize;
fn update(&mut self, data: &[u8]);
fn digest(&mut self, digest: &mut [u8]) -> Result<()>; fn into_digest(self) -> Result<Vec<u8>>
    where
        Self: Sized
, { ... } }

Hasher capable of calculating a digest for the input byte stream.

This provides an abstract interface to the hash functions used in OpenPGP. Digests can be are created using HashAlgorithm::context.

Required methods

fn algo(&self) -> HashAlgorithm

Returns the algorithm.

fn digest_size(&self) -> usize

Size of the digest in bytes

fn update(&mut self, data: &[u8])

Writes data into the hash function.

fn digest(&mut self, digest: &mut [u8]) -> Result<()>

Finalizes the hash function and writes the digest into the provided slice.

Resets the hash function contexts.

digest must be at least self.digest_size() bytes large, otherwise the digest will be truncated.

Provided methods

fn into_digest(self) -> Result<Vec<u8>> where
    Self: Sized

Finalizes the hash function and computes the digest.
