# Struct crypto::ghash::Ghash [−] [src]

    pub struct Ghash { /* fields omitted */ }

A structure representing the state of a GHASH computation

## Methods

### `impl Ghash`
[src]

#### `fn new(h: &[u8]) -> Ghash`

Creates a new GHASH state, with `h` as the key

#### `fn input_a(self, a: &[u8]) -> Ghash`

Feeds data for GHASH's A input

#### `fn input_c(self, c: &[u8]) -> GhashWithC`

Feeds data for GHASH's C input

#### `fn result(self) -> [u8; 16]`

Retrieve the digest result

## Trait Implementations

### `impl Copy for Ghash`
[src]

### `impl Clone for Ghash`
[src]

#### `fn clone(&self) -> Ghash`

Returns a copy of the value. Read more

#### `fn clone_from(&mut self, source: &Self)`
1.0.0

Performs copy-assignment from `source`. Read more

### `impl Mac for Ghash`
[src]

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

Process input data. Read more

#### `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. Read more

#### `fn output_bytes(&self) -> usize`

Get the size of the Mac code, in bytes.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
