Project description

starknet_pathfinder_crypto

Python wrapper of the Rust implementations of Pedersen and Poseidon hash functions from pathfinder.

Installation

pip install starknet_pathfinder_crypto

Usage

The functions implemented by this module are drop-in replacements for the pure-Python implementations used in cairo-lang:

You can use them directly, or monkey-patch cairo-lang:

import starknet_pathfinder_crypto
import starkware.crypto.signature.fast_pedersen_hash
import starkware.cairo.common.poseidon_hash

starkware.crypto.signature.fast_pedersen_hash.pedersen_hash_func = (
    starknet_pathfinder_crypto.pedersen_hash_func
)
starkware.crypto.signature.fast_pedersen_hash.pedersen_hash = (
    starknet_pathfinder_crypto.pedersen_hash
)
starkware.cairo.common.poseidon_hash.poseidon_hash = starknet_pathfinder_crypto.poseidon_hash
starkware.cairo.common.poseidon_hash.poseidon_hash_func = (
    starknet_pathfinder_crypto.poseidon_hash_func
)
starkware.cairo.common.poseidon_hash.poseidon_hash_many = (
    starknet_pathfinder_crypto.poseidon_hash_many
)
starkware.cairo.common.poseidon_hash.poseidon_perm = starknet_pathfinder_crypto.poseidon_perm
