Trait crypto::mac::Mac
[-] [+]
[src]
pub trait Mac { fn input(&mut self, data: &[u8]); fn reset(&mut self); fn result(&mut self) -> MacResult; fn raw_result(&mut self, output: &mut [u8]); fn output_bytes(&self) -> usize; }
The Mac trait defines methods for a Message Authentication function.
Required Methods
fn input(&mut self, data: &[u8])
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.
