Tool guide

MD5 and SHA checksum calculator

Verify file integrity or compare digests before and after transfer.

  • AlgorithmsMD5, SHA-1, SHA-256, SHA-384, and SHA-512.
  • File or textDrop a file or paste a string; copy any digest.
  • Web CryptoSHA family uses the browser crypto API locally.

Checksums are computed on your device; files are not uploaded.

How it works

  1. Select algorithms Pick one or more hash chips before computing.
  2. Add input Upload a file or paste text to hash.
  3. Compare Copy digests and match against publisher checksums.

FAQ

Are files uploaded for hashing?

No. MD5 and SHA digests are computed locally with browser APIs.

Which algorithms are available?

MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Select one or more chips before computing.

Can I hash text instead of a file?

Yes. Paste a string and run the same algorithms without uploading a file.

Is MD5 secure for passwords?

No. MD5 is for checksums and legacy compatibility, not password storage.

How do I verify a download?

Compute the digest of the downloaded file and compare it to the publisher checksum.

Why do digests differ from another tool?

Ensure you hash the same bytes, line endings, and text encoding. Binary versus text input must match.
