Common uses

  • Checking a downloaded file
  • Comparing content digests
  • Creating integrity records

Limitations

  • Hashing is one-way and is not encryption.
  • A checksum confirms matching bytes but not who produced a file.

FAQs

Is my file uploaded?

No. The browser reads it locally and passes the bytes to Web Crypto.

Which hash should I use?

SHA-256 is widely used for general integrity checks; use a specific algorithm when another system requires it.
