Hashing with Keccak256 Solidity Smart Contract Tutorial



Source link

The keccak256() function in Solidity computes the Keccak-256 hash of the input.

Some use cases are:
– Creating a deterministic unique ID from a input
– Commit-Reveal scheme
– Compact cryptographic signature (by signing the hash instead of a larger input)
