Struct orion::hazardous::mac::hmac::Tag

#[must_use]
pub struct Tag { /* fields omitted */ }

A type to represent the Tag that HMAC returns.

Exceptions:

An exception will be thrown if:

• slice is not 64 bytes.

Security:

• Avoid using unprotected_as_bytes() whenever possible, as it breaks all protections that the type implements.

Methods

impl Tag

#[must_use] pub fn from_slice(slice: &[u8]) -> Result<Tag, UnknownCryptoError>

Make an object from a given byte slice.

#[must_use] pub fn unprotected_as_bytes(&self) -> &[u8]

Return the object as byte slice. Warning: Should not be used unless strictly needed. This breaks protections that the type implements.

pub fn get_length(&self) -> usize

Return the length of the object.
