This crate provides traits which describe functionality of cryptographic hash functions and Message Authentication algorithms.
Traits in this repository are organized into the following levels:
- High-level convenience traits:
Mac. Wrappers around lower-level traits for most common use-cases. Users should usually prefer using these traits.
- Mid-level traits:
InnerInit. These traits atomically describe available functionality of an algorithm.
- Marker traits:
MacMarker. Used to distinguish different algorithm classes.
- Low-level traits defined in the
core_apimodule. These traits operate at a block-level and do not contain any built-in buffering. They are intended to be implemented by low-level algorithm providers only. Usually they should not be used in application-level code.
Additionally hash functions implement traits from the standard library:
Write. The latter is
std feature, which is usually enabled by default
by hash implementation crates.

Low-level traits operating on blocks and wrappers around them.
Define MAC test
Define resettable MAC test

Fixed size output value which provides a safe
Eq implementation that
runs in constant time.
Buffer length is not equal to hash output size.
The error type used in variable hash traits.
