Crate digest

This crate provides traits which describe functionality of cryptographic hash functions.

Traits in this repository can be separated into two levels:

• Low level traits: Input, BlockInput, Reset, FixedOutput, VariableOutput, ExtendableOutput. These traits atomically describe available functionality of hash function implementations.
• Convenience trait: Digest, DynDigest. They are wrappers around low level traits for most common hash-function use-cases.

Additionally hash functions implement traits from std: Default, Clone, Write. (the latter depends on enabled-by-default std crate feature)

The Digest trait is the most commonly used trait.

Traits

BlockInput	Trait to indicate that digest function processes data in blocks of size BlockSize.
Digest	The Digest trait specifies an interface common for digest functions.
DynDigest	The DynDigest trait is a modification of Digest trait suitable for trait objects.
ExtendableOutput	Trait which describes extendable-output functions (XOF).
FixedOutput	Trait for returning digest result with the fixed size
Input	Trait for processing input data
Reset	Trait for resetting hash instances
VariableOutput	Trait for returning digest result with the variable size
XofReader	Trait for describing readers which are used to extract extendable output from XOF (extendable-output function) result.
