About this page

Calculate a local SHA hash for a file without uploading it to SpeedVerge.

How to use it

  1. Select the required SHA algorithm before entering text or choosing a file.
  2. Use the exact original bytes, including the intended encoding and line endings.
  3. Generate the complete digest locally in the browser.
  4. Compare every character with a checksum obtained from an independent trusted source.

How to interpret the result

Identical content processed with the same algorithm produces the same digest. A different digest proves the inputs differ, but a match does not identify who created the content.

Privacy and limitations

A checksum is not a malware scan, digital signature or safe password-storage method. Plain fast hashes should not be used to store account passwords.

Recommended next step

Confirm the source of the reference checksum and use a digital signature or vendor verification process when authenticity matters.
