Yes. Every update SyncNow downloads is checked with SHA-256 before a single byte is applied.
SHA-256 is a cryptographic fingerprint. SyncNow knows the exact fingerprint of the official build published on www.syncnow.it. After it downloads the new version, it computes the fingerprint of what actually arrived and compares the two. If they match exactly, the update is trusted and applied. If they differ in any way, the download is rejected and discarded, and your current version keeps running untouched.
What this protects you from
- A file corrupted in transit over the network.
- A file that was tampered with and is not the build we shipped.
- A partial or interrupted download being applied by mistake.
You never have to verify anything by hand. SyncNow does it for you on every single download, which is what makes automatic updating safe to leave on.
