SHA-256

Input

About this tool

Not the same as Keccak. Use SHA-256 when a standard or off-chain system (Bitcoin, some IPFS tooling) specifies it.

All computation happens locally in your browser. No inputs are sent to a server.

Warning

Smart contracts almost always use keccak256, not SHA-256. Don’t mix them up when verifying Solidity preimages.
