About this tool
Download pages publish checksums for a reason. This free file hash tool digests a file so you can verify SHA-256 (or similar) against the publisher’s value. Confirm installers and datasets against the publisher’s checksum.
How to use
- Select the file you downloaded.
- Choose the hash algorithm matching the publisher’s checksum.
- Compute the digest locally.
- Compare it character-for-character with the official hash.
