Crate miden_stateful_hasher 

Stateful sponge-like hashers for cryptographic hashing.

This crate provides the StatefulHasher trait and implementations that maintain an evolving state during hashing. This interface is used by commitment schemes and Merkle trees to incrementally absorb data and squeeze out digests.

Implementations

• StatefulSponge: Wraps a permutation with proper sponge semantics
• SerializingStatefulSponge: Serializes field elements to binary before absorbing
• ChainingHasher: Uses chaining mode H(state || input) with a regular hasher
• TruncatingHasher: Wraps a hasher and returns a shorter fixed digest (prefix)

Structs

ChainingHasher

An adapter that chains state with new input, hashing state || encode(input).

SerializingStatefulSponge

An adapter that serializes field elements to binary and delegates to an inner StatefulHasher.

StatefulSponge

A stateful sponge wrapper around a cryptographic permutation.

TruncatingHasher

Hasher analogue of p3-symmetric’s TruncatedPermutation.

Traits

Alignable

Defines alignment for stateful hashers.
