Crate digest

This crate provides traits for describing funcionality of cryptographic hash functions.

By default std functionality in this crate disabled. (e.g. method for hashing Readers) To enable it turn on std feature in your Cargo.toml for this crate.

Re-exports

pub extern crate generic_array;

Macros

impl_opaque_debug

Macro for defining opaque Debug implementation. It will use the following format: "HasherName { ... }". While it's convinient to have it (e.g. for including in other structs), it could be undesirable to leak internall state, which can happen for example through uncareful logging.

Structs

InvalidBufferLength	The error type for variable hasher result
InvalidLength	The error type for variable digest output
InvalidOutputSize	The error type for variable hasher initialization

Traits

BlockInput	Trait to indicate that digest function processes data in blocks of size BlockSize. Main usage of this trait is for implementing HMAC generically.
Digest	The Digest trait specifies an interface common for digest functions.
ExtendableOutput	Trait which describes extendable output (XOF) of hash functions. Using this trait you first need to get structure which implements XofReader, using which you can read extendable output.
FixedOutput	Trait for returning digest result with the fixed size
Input	Trait for processing input data
VariableOutput	Trait for returning digest result with the varaible size
XofReader	Trait for decribing readers which are used to extract extendable output from the resulting state of hash function.
