Struct blake2::Blake2b

pub struct Blake2b { /* fields omitted */ }

Hash function context.

Methods

impl Blake2b

fn new_keyed(k: &[u8]) -> Self

Creates a new hashing context with a key.

Trait Implementations

impl Copy for Blake2b

impl Clone for Blake2b

fn clone(&self) -> Blake2b

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Blake2b

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for Blake2b

fn default() -> Self

Returns the "default value" for a type.

impl BlockInput for Blake2b

type BlockSize = U64

impl Input for Blake2b

fn process(&mut self, input: &[u8])

Digest input data. This method can be called repeatedly for use with streaming messages.

impl FixedOutput for Blake2b

type OutputSize = U64

fn fixed_result(self) -> GenericArray<u8, U64>

Retrieve the digest result. This method consumes digest instance.

impl VariableOutput for Blake2b

fn variable_result(self, buf: &mut [u8]) -> Result<&[u8], InvalidLength>

Retrieve the digest result into provided buffer. Length of the output equals to the input buffer size. In case of invalid length Err(InvalidLength) will be returned. This method consumes digest instance.

impl Mac for Blake2b

type OutputSize = U64

fn new(key: &[u8]) -> Self

Create new MAC instance. DO NOT USE low-entropy keys (e.g. passwords)!

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

Process input data.

fn result(self) -> MacResult<Self::OutputSize>

Obtain the result of a Mac computation as a MacResult.

fn verify(self, code: &[u8]) -> bool

Check if code is correct for the processed input
