Hash anything, right here
Eight calculators, running entirely in this tab. Type or paste anything and every digest resolves as you type — nothing is uploaded, nothing is stored, and the page keeps working with the network switched off. These are the same eight algorithms Rocket Hash computes on your Mac, where they also run over files and whole folders.
64 hex characters, the digest almost everything asks for.
SHA-512512-bit128 hex characters from the 64-bit member of the SHA-2 family.
SHA-384384-bit96 hex characters — SHA-512 truncated, with a different start.
SHA3-256256-bitKeccak’s sponge, not a SHA-2 variant, at 256 bits.
SHA3-512512-bitKeccak at 512 bits — 128 hex characters.
MD5128-bit32 hex characters. Still everywhere, still fine for one job.
SHA-1160-bit40 hex characters. Broken for signatures, alive in Git.
CRC3232-bitEight hex characters of error detection, as used by ZIP and PNG.
Learn how to use them
What is a checksum, and when do you actually need one?
What the fingerprint actually proves, what it does not, and the four moments in a normal week when it earns its keep.
Which hash algorithm should I use?
A decision tree, not a ranking. Four questions and you have your answer.
How to verify a download on Mac
Paste the published checksum, drop the file, read the verdict. Plus where the real checksum lives.
Why do two tools give different hashes for the same thing?
Six causes, in the order they actually happen. The first one accounts for half of them.
