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

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

    pub 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

`pub fn algo(&self) -> HashAlgorithm`[src]

Returns the algorithm.

`pub fn digest_size(&self) -> usize`[src]

Size of the digest in bytes

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

Writes data into the hash function.

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

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
