A hash is a short fingerprint of a file: the same input always gives the same value, and any change shows up immediately. Drop in a file to compute its MD5, SHA-1 or SHA-256, so you can verify a download or compare two files, all in your browser.

Common use cases
Verify a downloadCompare a file's hash against the one the source published.
Check two files matchConfirm two copies are byte-for-byte identical.
Spot a changeSee whether a file was altered since you last hashed it.
Get a checksum to shareProduce a hash others can use to verify what you sent.
Good to know
A hash is one-way, not encryptionYou cannot turn a hash back into the file. It is a fingerprint for checking, not a way to hide or recover data.
Match the algorithm to the sourceVerify with the same algorithm the publisher used. A SHA-256 hash will not match an MD5 one for the same file.
MD5 and SHA-1 are weak for securityThey are fine for spotting accidental corruption, but both are broken for tamper-proofing. Use SHA-256 where security matters.
One byte changes everythingEven a tiny edit produces a completely different hash. That is the point, and why a mismatch means the files are not identical.
