Module crypto 

High-level utilities for cryptographic operations used in Starknet.

Structs

ExtendedSignature

Stark ECDSA signature with v, useful for recovering the public key.

HashFunction

A hash function that is used in Starknet.

Signature

Stark ECDSA signature.

StatefulHasher

A stateful hasher that can be updated with messages and finalized to produce a hash.

Enums

EcdsaSignError

Errors when performing ECDSA sign operations.

EcdsaVerifyError

Errors when performing ECDSA verify operations.

Functions

compute_hash_on_elements

Computes the Pedersen hash of a list of Felt.

ecdsa_sign

Signs a hash using deterministic ECDSA on the STARK curve. The signature returned can be used to recover the public key.

ecdsa_verify

Verified an ECDSA signature on the STARK curve.

pedersen_hash

Computes the Starkware version of the Pedersen hash of x and y. All inputs are little-endian.
