lib.rs

1//! Low-level cryptography utilities for Starknet. Features include:
2//!
3//! - ECDSA operations
4//!   - [Signing hashes](fn.sign)
5//!   - [Verifying signatures](fn.verify)
6//!   - [Recovering public keys from signatures](fn.recover)
7//! - [Pedersen hash](fn.pedersen_hash)
8//! - Poseidon hash
9//! - [RFC-6979](fn.rfc6979_generate_k)
10//!
11//! # Warning
12//!
13//! You're advised to use high-level crypto utilities implemented by the `starknet-rust-core` crate if
14//! you're not familiar with cryptographic primitives. Using these low-level functions incorrectly
15//! could result in catastrophic consequences like leaking your private key.
