downloads tips

✅

Paste the SHA-256 from the download page; a green ✓ confirms the file is intact and authentic.

⚠️

A red ✗ means the file differs — it may be corrupted in transit or tampered with. Re-download from a trusted source.

💿

Especially important for OS images, installers, and security tools.

🔒

The file is hashed locally — no need to upload a big installer anywhere.
