​
Parameters

  • jsonrpc — the JSON-RPC protocol version (always “2.0”)
  • method — the method name (always “web3_sha3”)
  • params — array containing method parameters
    • data — hex-encoded data to be hashed
  • id — request identifier (number or string)

​
Response

  • jsonrpc — the JSON-RPC protocol version (“2.0”)
  • id — the request identifier that matches the request
  • result — hex-encoded Keccak-256 hash of the input data

​
Use case

The jsonrpc web3_sha3 method is used for:
  • Computing Keccak-256 hashes for data verification and integrity checks
  • Generating hash values for smart contract function signatures and event topics through Web3 interfaces
  • Implementing cryptographic operations in dApps that require consistent hashing algorithms
  • Creating data fingerprints and merkle tree components for blockchain applications

Body

application/json

Response

200 - application/json

Keccak-256 hash of the input data

The response is of type object.
