Crypto hash and ENS namehash calculator
Written by Agorean from what the endpoint says about itself
Computes keccak256, sha256, function selectors, event topics, or ENS namehashes.
Give it a string or hex input and an algorithm, and it computes the hash. It supports keccak256, sha256, a 4-byte function selector, an event topic0, or an ENS namehash or labelhash. It is for anyone who needs one of these standard crypto hashes without running the calculation themselves.
WHEN TO USE THIS
When: I need the keccak256 or sha256 hash of a string
For example: Set algo to keccak256 or sha256 and pass the string as input.
When: I need the 4-byte function selector for a Solidity function signature
For example: Set algo to selector and input to the function signature, like transfer(address,uint256).
When: I need the topic0 hash for an event to filter logs
For example: Set algo to event_topic and input to the event signature.
When: I need the ENS namehash or labelhash for a name
For example: Set algo to namehash or labelhash and input to the ENS name.
