Verify before you install

Every release is code-signed and published with a SHA-256 checksum. Don't install any build that doesn't match both values here.

Current release:
ViolaSetup-1.0.0.exe · ~586 MB
SHA-256:
f3db3c21584010ab845a640e196c33aad9ecfdcbf3c931c407f276922737dff4
Authenticode signer:
CN=Jihad Shkoukani, O=Jihad Shkoukani, L=Milwaukee, S=Wisconsin, C=US
Signing certificate SHA-1 thumbprint:

Signing infrastructure:
Azure Code Signing · account ViolaSigning, profile ViolaRelease

How to verify on Windows (PowerShell):

# 1. Check the Authenticode signature and thumbprint
Get-AuthenticodeSignature .\ViolaSetup-1.0.0.exe

# 2. Check the SHA-256
Get-FileHash .\ViolaSetup-1.0.0.exe -Algorithm SHA256

The Thumbprint field of the SignerCertificate must match the value above. The Hash from Get-FileHash must match the SHA-256. If either differs, do not install; instead email [email protected].

Note on cert lifecycle: Authenticode signatures remain valid after the signing certificate's own expiry date, provided the signature was produced while the cert was active (PKIX § 4.1). A future release will carry a fresh certificate; that release's values will appear here. Historical values are preserved in network-flows release notes when they change.
