How it works
- Text or file?
Paste a string, or drop a file to hash its full contents.
- Pick the algorithms
All four SHA variants are produced at once. SHA-256 is the one you want 99% of the time.
- Compare or copy
Paste the 'official' hash next to it and compare visually — or hex by hex.
Questions people actually ask
Why no MD5?
Browsers no longer expose it for good reason — it's broken for security use. If you need MD5 to match an old checksum, say so via the contact page.
Is a hash the same as encryption?
No — hashing is one-way by design. You can't get the file back from its hash; you can only check that another copy matches.
