Struct crypto_mac::Output

source · [−]

pub struct Output<M: Mac> { /* private fields */ }

Expand description

Output is a thin wrapper around bytes array which provides a safe Eq implementation that runs in a fixed time.

Implementations

source

impl<M: Mac> Output<M>

source

pub fn new(bytes: GenericArray<u8, M::OutputSize>) -> Output<M>

Create a new MAC Output.

source

pub fn into_bytes(self) -> GenericArray<u8, M::OutputSize>

Get the MAC tag/code value as a byte array.

Be very careful using this method, since incorrect use of the tag value may permit timing attacks which defeat the security provided by the Mac trait.
