Crate digest[−][src]
This crate provides traits which describe functionality of cryptographic hash functions.
Traits in this repository are organized into high-level convenience traits, mid-level traits which expose more fine-grained functionality, and low-level traits intended to only be used by algorithm implementations:
- High-level convenience traits:
Digest
,DynDigest
. They are wrappers around lower-level traits for most common hash-function use-cases. - Mid-level traits:
Update
,BlockInput
,Reset
,FixedOutput
,VariableOutput
,ExtendableOutput
. These traits atomically describe available functionality of hash function implementations. - Low-level traits:
FixedOutputDirty
,VariableOutputDirty
,ExtendableOutputDirty
. These traits are intended to be implemented by low-level algorithm providers only and simplify the amount of work implementers need to do and therefore shouldn’t 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.
The Digest
trait is the most commonly used trait.
