Expand description
Hasher capable of calculating a digest for the input byte stream.
This provides an abstract interface to the hash functions used in
OpenPGP. Digest
s can be are created using HashAlgorithm::context
.
Required methods
fn algo(&self) -> HashAlgorithm
fn algo(&self) -> HashAlgorithm
Returns the algorithm.
fn digest_size(&self) -> usize
fn digest_size(&self) -> usize
Size of the digest in bytes
Provided methods
Implementations on Foreign Types
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.
