Web3Utilities
web3utilities crate is a library offering commonly used cryptographic and timestamp data structures common in Web3, asymmetric cryptography, symmetric cryptography and timestamps.
This crate has implementations for constant-time equality by default for all data structures that involve symmetric, timestamp and asymmetric cryptography. There are also fmt::Debug implementations using Base58 encoding for Ed25519 and SR25519 data structures and hex encoding for X25519 and hashing data structures.
Utilities struct is also provided for commonly methods for conversions.
