Vether
Security · architecture

No magic promises. A public spec.

What you can rely on, and what we will never promise. Vether's security rests on explicit architectural choices.

01

Local-first, no exceptions

The binary runs entirely on your machine. No product telemetry, no phone-home, no user database on our servers. Our infrastructure only receives payment and license-validation requests — nothing else.

02

Authenticode-signed binaries

Every Windows release is signed with an OV code-signing certificate issued to our trade name. Windows verifies the signature before installation and at launch. SmartScreen recognizes the publisher without warnings after the first installs.

03

Published SHA-256 hashes

The SHA-256 hash of every Windows x64 release is published on the download page, in the changelog, and signed in the release manifest. You can verify the file's integrity before running it with Get-FileHash in PowerShell.

04

Anonymous Ed25519 license

Periodic license validation is Ed25519-signed and transmits no hardware identifier. Only an opaque license token travels, along with a random nonce. No fingerprint, no user SID, no HWID.

05

No server-side logs

Our servers keep no product-usage logs. Technical access logs (infrastructure security: intrusion attempts, anomalies) expire automatically within 30 days and are never correlated with customer accounts.

06

Responsible disclosure

Found a vulnerability? Write to us PGP-encrypted at [email protected]. First response within 72 h, coordinated fix. Acknowledgements program published in /security.txt at the site root.

Open stack

Built on foundations
proven over time.

Rather than reinventing cryptography, Vether orchestrates the open-source tools that have passed the test of time — and adds the interface, usage discipline and support they lack for a general audience.

Algorithms used
& what each is for.

No home-grown cryptography. Every algorithm is standard, published and widely audited. Vether's job is to invoke them correctly, with the right parameters, at the right moment.
