Crate digest 

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: [Digest], [DynDigest], [Mac]. Wrappers around lower-level traits for most common use-cases. Users should usually prefer using these traits.
• Mid-level traits: Update, FixedOutput, FixedOutputReset, ExtendableOutput, ExtendableOutputReset, XofReader, VariableOutput, Reset, KeyInit, and InnerInit. These traits atomically describe available functionality of an algorithm.
• Marker traits: [HashMarker], [MacMarker]. Used to distinguish different algorithm classes.
• Low-level traits defined in the core_api module. 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: Default, Clone, Write. The latter is feature-gated behind std feature, which is usually enabled by default by hash implementation crates.

Modules

consts

core_apicore-api

Low-level traits operating on blocks and wrappers around them.

Macros

impl_oid_carrier

Implement dummy type with hidden docs which is used to “carry” hasher OID for [CtVariableCoreWrapper].

Structs

InvalidBufferSize

Buffer length is not equal to hash output size.

InvalidLengthmac

The error type returned when key and/or IV used in the KeyInit, KeyIvInit, and InnerIvInit slice-based methods had an invalid length.

InvalidOutputSize

The error type used in variable hash traits.

Traits

ExtendableOutput

Trait for hash functions with extendable-output (XOF).

ExtendableOutputReset

Trait for hash functions with extendable-output (XOF) able to reset themselves.

FixedOutput

Trait for hash functions with fixed-size output.

FixedOutputReset

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

InnerInitmac

Types which can be initialized from another type (usually block ciphers).

KeyInitmac

Types which can be initialized from key.

OutputSizeUser

Types which return data with the given size.

Reset

Resettable types.

Update

Types which consume data with byte granularity.

VariableOutput

Trait for hash functions with variable-size output.

VariableOutputReset

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

XofReader

Trait for reader types which are used to extract extendable output from a XOF (extendable-output function) result.

Type Aliases

Keymac

Key used by KeySizeUser implementors.

Output

Output array of OutputSizeUser implementors.
