FAQ

What is a SHA-256 hash?

SHA-256 is a cryptographic hash function that produces a unique 256-bit (32-byte) signature for a file. It is commonly used to verify file integrity.

How do I verify a file's integrity?

Compute the file's SHA-256 hash using our tool and compare it with the checksum provided by the source. If they match, the file is intact.

Is this tool free?

Yes, Hash Check Shell Extension is completely free to use.

Does it work on all Windows versions?

It supports Windows 7, 8, 10, and 11.
