Poseidon

This repository contains:

• poseidon377: an instantiation of the Poseidon hash function for decaf377
• poseidon-paramgen: an independent implementation of Poseidon parameter generation
• poseidon-parameters: types that represent Poseidon parameters
• poseidon-permutation: an independent implementation of the Poseidon permutation
• poseidon-consistency: property-based tests for consistency between Poseidon implementations
• poseidon-tests: test vectors for poseidon-parameters and poseidon377

Audits

poseidon-paramgen was audited by NCC Group in Summer 2022. Note that the audit covered only the parameter generation described in the original Poseidon paper. The Poseidon2 parameter generation is not yet audited.
