Struct Blake2s 

pub struct Blake2s { /* private fields */ }

Blake2s Context

Implementations

impl Blake2s

pub fn new(outlen: usize) -> Self

Create a new Blake2s context with a specific output size in bytes

the size need to be between 0 (non included) and 32 bytes (included)

pub fn new_keyed(outlen: usize, key: &[u8]) -> Self

Similar to new but also takes a variable size key to tweak the context initialization

pub fn reset(&mut self)

Reset the context to the state after calling new

pub fn reset_with_key(&mut self, key: &[u8])

Reset the blake2 context with a key

pub fn blake2s(out: &mut [u8], input: &[u8], key: &[u8])

Compute the blake2 function as one call

Trait Implementations

impl Clone for Blake2s

fn clone(&self) -> Blake2s

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Digest for Blake2s

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

Append message data in the digest state.

fn reset(&mut self)

Reset the digest. This method must be called after result() and before supplying more data.

fn result(&mut self, out: &mut [u8])

Retrieve the digest result. This method may be called multiple times.

fn output_bits(&self) -> usize

Get the output size in bits.

fn block_size(&self) -> usize

Get the block size in bytes.

fn output_bytes(&self) -> usize

Get the output size in bytes.

fn input_str(&mut self, input: &str)

Convenience function that feeds a string into a digest.

fn result_str(&mut self) -> String

Convenience function that retrieves the result of a digest as a String in hexadecimal format.

impl Mac for Blake2s

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

Process input data.

fn reset(&mut self)

Reset the Mac state to begin processing another input stream.

fn result(&mut self) -> MacResult

Obtain the result of a Mac computation as a MacResult.

fn raw_result(&mut self, output: &mut [u8])

Obtain the result of a Mac computation as u8. This method should be used very carefully since incorrect use of the Mac code could result in permitting a timing attack which defeats the security provided by a Mac function.

fn output_bytes(&self) -> usize

Get the size of the Mac code, in bytes.
