Keccak hash

Hash text exactly as Solidity does onchain.

Solidity 0.8.36REPL mode

Why use this example

Use this pattern when you need to check the exact bytes, selector, hash, or decoded values that Solidity will produce. The entry isolates keccak hash so its input, result, and state changes stay easy to compare.

Solidity to run

string memory greeting = "hello"
keccak256(bytes(greeting))

What to expect

The UTF-8 bytes for “hello” are hashed and the resulting bytes32 value is displayed directly beneath the entry.

Continue the investigation

Change a value, add another expression, or open Inspect after the run. Accepted entries remain available to the next entry, and the clean replay keeps the complete result reproducible.
