Hash Functions for Zero-Knowledge Applications Zoo

This repository contains several Rust implementations of different hash functions for zero-knowledge applications and will be extended frequently.

The repository already contains the following implementations:

• plain_impls contains a comparison of the plain performance of various hash functions.
• bounties contains toy instances and implementations of some hash functions used for the Cryptanalysis Bounties.
• bellman contains a comparison of different hash functions in zero-knowledge applications using the bellman_ce library.

Plain Performance Comparison of different Hash Functions for ZKP

This repository contains Rust implementations of different hash functions for Zero-Knowledge applications. For benchmarks we refer to [1] and [2].

Hash Functions

The following hash functions are already implemented:

• ReinforcedConcrete
• Monolith
• Poseidon
• Rescue
• Rescue-Prime
• Griffin
• Neptune
• Feistel-MiMC
• Pedersen-Hash, code extracted from Zcash
• Sinsemilla, code extracted from Orchard

We also benchmark against various classical hash algorithms implemented in RustCrypto.
