How we scored this 95 out of 100
| Signal | Finding | Points |
|---|---|---|
| SHA-256 hash published | 1 of 1 installers ship a SHA-256 hashWithout a published hash there is no way to prove the file you downloaded is the file the publisher built. | 30 / 30 |
| Binary provenance | 1 on a recognised distribution platformThe strongest signal against a repackaged installer: the file should come from the publisher, not from a mirror nobody vouches for. | 29.8 / 35 |
| Served over HTTPS | 1 of 1 over HTTPSAn installer fetched over plain HTTP can be modified in transit. | 15 / 15 |
| Release recency | last release about 0 months agoSoftware that has not shipped in years accumulates unpatched vulnerabilities. | 15 / 15 |
