Checksum Generator for Downloads
Generate a SHA-256 or MD5 checksum to publish next to a download. Hash the release file locally and copy the digest.
Part of the free Hash Generator. Runs in your browser — nothing is uploaded.
Checksum Generator for Downloads
When you ship a binary, publish its SHA-256 next to the link. Users can hash their copy and see that it matches. Generate the digest from the same file you uploaded.
Worked example: A published checksum line
Release note
SHA256 (hello.txt) = 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824
Digest to publish
2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824
Practical tip
Publish SHA-256. Offer MD5 only if an older pipeline still requires it, and label it as a corruption check, not a security check.
How to use this Hash Generator
- 1Use the live tool above — it runs entirely in your browser and never uploads your data.
- 2Paste the sample from the worked example, or use your own input.
- 3Copy the result, then adapt the same steps in your editor, script, or pipeline.
Checksum Generator for Downloads FAQs
Where should I put the checksum?
On the download page, in the GitHub release notes, or in a SHA256SUMS file in the same directory.
Should I sign the checksums?
Yes for software people install. A GPG-signed SHA256SUMS file stops an attacker who can change both the binary and the hash on the page.
