Features

• Smart Contract Security - Provides a security utility library for implementing digital signature verification in Ethereum contracts.
• Cryptographic Signature Verification - Validates cryptographic signatures within Solidity smart contracts to ensure authenticity.
• Hash-Based Signature Verifiers - Functions as a specialized tool for validating hash-based signatures to confirm data origin.
• WOTS+ Verifiers - Implements signature validation for Winternitz One-Time Signatures Plus.
• Digital Signature Libraries - Provides a library for verifying hash-based one-time signatures on the blockchain.
• Digital Signature Validators - Provides tools for validating cryptographic signatures within a virtual machine environment.
• One-Time Signature Validators - Implements validation for one-time signatures to ensure a message is only processed once.
• On-Chain Authentications - Enables proving sender identity within the EVM using hash-based digital signatures.
• One-Time Signature Verifiers - Confirms single-use hash-based signatures to prevent replay attacks.
• Hash-Chain Authentications - Provides identity verification through the validation of pre-calculated hash chains.
• Merkle Tree Utilities - Includes utilities for verifying leaf nodes via Merkle tree path proofs.
• Preimage Proofs - Verifies claimants by matching provided secret values against stored hashes.
• Key Usage Tracking - Tracks the usage of public keys in contract storage to eliminate replay attacks.
• Smart Contract Integrity Checks - Uses cryptographic checks to verify data integrity before it is processed by a contract.
