Vitamin C Traits

This crate is part of the Vitamin C 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.

Traits

FixedOutput

Trait for hash functions with fixed-size output.

FixedOutputReset

Trait for hash functions with fixed-size output able to reset themselves.

KeyInit

KeySize

OutputSize

Defines the size of the output of a hash function.

Update

Trait for updating a hash with input data with a specific input type. This differs from the Update trait in digest in that it takes a specific input type. This allows us to reason about the input type and its sensitivity.
