How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
hashsigs-solidity is a cryptographic signature library and security utility for Ethereum smart contracts. It functions as a hash-based signature verifier designed to confirm data origin and integrity within a virtual machine environment. The project focuses on on-chain cryptographic authentication, specifically the verification of one-time signatures to prevent replay attacks. It implements signature validation for Winternitz One-Time Signatures Plus to ensure that data has not been tampered with before it is processed by a contract. The library covers a broad range of cryptographic capabili
hashsigs-ts is a TypeScript cryptography library used to generate and verify digital signatures through one-time cryptographic schemes. It functions as a hash-based signature tool that creates secure signatures without relying on asymmetric encryption. The library provides tools for cryptographic identity verification and data integrity validation. It utilizes a one-time signature generation process to ensure that data remains unaltered and that the origin of a message can be proven. The implementation manages raw cryptographic data using typed arrays and employs pure functions to ensure con
hashsigs-py is a hash-based signature library for Python used to generate and verify one-time digital signatures. It employs hash chains and seed-based key derivation to authenticate data and ensure message integrity. The library includes a high-performance compiled cryptography backend to accelerate signature computation and processing. For compatibility, it maintains a pure Python fallback implementation to ensure functionality when the compiled backend is unavailable. The project provides tools for digital key pair management, allowing for the deterministic generation of public and privat
This library provides a collection of low-level mathematical primitives for Curve25519 and Ristretto group operations. It serves as a foundation for building secure cryptographic protocols, offering tools for elliptic curve arithmetic, key exchange, and digital signature generation. The implementation prioritizes side-channel resistance by utilizing constant-time arithmetic logic across all operations, ensuring that secret-dependent timing variations are prevented. It leverages the Rust type system to enforce state validity, making illegal group elements unrepresentable at compile time. To ma
