Trait Implementations

impl<PARAMS: Clone + SHA2Params> Clone for SHA256Internal<PARAMS>

fn clone(&self) -> SHA256Internal<PARAMS>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<PARAMS: SHA2Params> Default for SHA256Internal<PARAMS>

fn default() -> Self

Returns the “default value” for a type.

impl<PARAMS: SHA2Params> Drop for SHA256Internal<PARAMS>

fn drop(&mut self)

Executes the destructor for this type.

impl<PARAMS: SHA2Params> Hash for SHA256Internal<PARAMS>

fn block_bitlen(&self) -> usize

As per FIPS 180-4 Figure 1

fn do_final_partial_bits( self, partial_byte: u8, num_partial_bits: usize, ) -> Result<Vec<u8>, HashError>

TODO: This is defined in FIPS 180-4 s. 5.1.2 TODO: https://pages.nist.gov/ACVP/draft-celi-acvp-sha.html TODO: Could implement if there is demand.

fn do_final_partial_bits_out( self, partial_byte: u8, num_partial_bits: usize, output: &mut [u8], ) -> Result<usize, HashError>

TODO: This is defined in FIPS 180-4 s. 5.1.2 TODO: https://pages.nist.gov/ACVP/draft-celi-acvp-sha.html TODO: Could implement if there is demand.

fn output_len(&self) -> usize

The size of the output in bytes.

fn hash(self, data: &[u8]) -> Vec<u8>

A static one-shot API that hashes the provided data. data can be of any length, including zero bytes.

fn hash_out(self, data: &[u8], output: &mut [u8]) -> usize

A static one-shot API that hashes the provided data into the provided output slice. data can be of any length, including zero bytes. The return value is the number of bytes written.

fn do_update(&mut self, block: &[u8])

Provide a chunk of data to be absorbed into the hashes. data can be of any length, including zero bytes. do_update() is intended to be used as part of a streaming interface, and so may by called multiple times.

fn do_final(self) -> Vec<u8>

Finish absorbing input and produce the hashes output. Consumes self, so this must be the final call to this object.

fn do_final_out(self, output: &mut [u8]) -> usize

Finish absorbing input and produce the hashes output. Consumes self, so this must be the final call to this object.

fn max_security_strength(&self) -> SecurityStrength

Returns the maximum security strength that this KDF is capable of supporting, based on the underlying primitives.
