This crate is part of the [Vitamin C](https://github.com/cipherstash/vitaminc) framework to make cryptography code healthy.

This crate provides traits for hashing and encryption algorithms.
These are very similar to the traits provided by the `digest` and other crates in the RustCrypto project
with some key differences:

* The `Update` trait takes a specific input type. This allows us to reason about the input type and its sensitivity.
* The `Output` traits are generic over the output type. This allows us to reason about the output type and its sensitivity.
* All types have a trait bound of [Controlled]
* `const` generics are used to specify the output size of the hash instead of GenericArray.

Async versions of some of these traits are provided in the `async-traits` crate.
