Frequently Asked Questions
When should I pick Keccak-512?
Choose it when documentation or test vectors specify the 512-bit Keccak width. For Ethereum-style 256-bit hashes, use Keccak-256 instead.
Does uppercase hex change the hash?
No. Letter case is only a display preference; the underlying digest bytes are identical.
Are binary files supported?
This page hashes the text you paste. For file checksums, use a dedicated file hash tool that reads bytes directly.
