Frequently asked questions
What is a SHA-256 hash useful for?
It helps verify that a file exactly matches the expected version and has not changed.
Do I have to enter an expected value?
No. You can simply display and copy the calculated hash.
Is there a fixed file-size limit?
No, there is no product file-size cap. The file is hashed locally in fixed small chunks; browser, filesystem, runtime and available memory can still impose practical limits.
