What Is the File Checksum Calculator?

The File Checksum Calculator reads a selected file locally and produces a cryptographic SHA digest. It can also hash entered text for quick comparisons.

How It Works

Choose an algorithm, select a file or enter text, then calculate and compare the hexadecimal digest with a trusted value.

When to Use It

Use it to detect download corruption or confirm that two byte-identical files match.

Frequently Asked Questions

Does A Matching Hash Prove A File Is Safe?
No. It proves byte equality with the compared digest; that digest must come from a trusted separate source.
