[][src]Struct sequoia_openpgp::crypto::hash::Context

pub struct Context { /* fields omitted */ }

State of a hash function.

Methods

impl Context[src]

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<D: AsRef<[u8]>>(&mut self, data: D)[src]

Writes data into the hash function.

pub fn digest<D: AsMut<[u8]>>(&mut self, digest: D)[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.
