- Identify trusted mirror sources

Select mirrors listed on the official project website that serve files over HTTPS. Secure protocols prevent tampering during transfer, and the project’s maintainers regularly audit those endpoints. When a mirror appears in the official download table, it already passed the initial verification step.

Check the SSL certificate chain of each mirror before adding it to your source list. Use tools such as openssl s_client or browser inspection to confirm that the certificate is issued by a recognized authority and has not expired. A valid certificate reduces the risk of man‑in‑the‑middle attacks.

Compare checksums provided by the upstream source with the files you receive from the mirror. Download the SHA256 hash from the project’s release page, run sha256sum on the downloaded archive, and match the values. Any discrepancy signals a compromised mirror.

Consult community feedback platforms–forums, issue trackers, and aviator game mailing lists–to see which mirrors receive regular positive reports. Mirrors that consistently rank high for speed and reliability while showing no recent security complaints are safe choices for long‑term use.

Steps to Verify Mirror Authenticity Before Logging In

Check the URL carefully; ensure it matches the official domain exactly, paying attention to case, subdomains, and hyphens.

Validate the TLS certificate chain by clicking the padlock icon, confirming the issuer is a recognized Certificate Authority, and that the certificate has not expired.

Download the published checksum file from the primary source, then run sha256sum (or the algorithm specified) on the mirror’s package and compare the values.

Obtain the PGP signature from the official site, import the maintainer’s public key, and run gpg --verify against the mirror’s files to confirm authenticity.

Query the DNS records for the mirror’s hostname, enable DNSSEC validation, and verify that the resolved IP matches the one listed on the authoritative server.

Consult a curated trust database such as the Open Source Mirror Trust List; cross‑reference the mirror’s fingerprint with entries that have been audited by the community.

Perform a read‑only operation–like fetching a small, non‑sensitive file–before entering any credentials, and inspect the response for anomalies.

Record each verification step in a personal log or team wiki; this documentation speeds up future checks and provides evidence if a mirror later shows unexpected behavior.
Check SSL certificates and domain age
Verify the SSL certificate chain before you trust a mirror. Run openssl s_client -connect example.com:443 -servername example.com and confirm that every intermediate certificate links back to a recognized root authority. If the chain breaks or includes self‑signed nodes, reject the source immediately.

Inspect expiration dates and revocation status with tools such as SSL Labs or Qualys. A certificate that expires within the next 30 days or appears on a CRL list should raise a red flag. Record the notBefore and notAfter timestamps; a short validity window often signals a hastily set‑up site.

Determine domain age through a WHOIS lookup. Domains older than 12 months typically carry more reputation weight, while those created within the last few weeks are worth scrutinizing. Cross‑reference the registration date with the creation date of the SSL certificate; mismatched timelines can indicate a recently acquired, potentially unsafe mirror.

Combine these checks into a quick checklist: (1) full certificate chain validation, (2) expiration > 90 days, (3) no revocation entries, (4) domain age > 1 year. Apply the list to every candidate, and you’ll keep the mirror pool both reliable and secure.
